The underlying information was acquired from carriers holding numbering resources and was analyzed as part of our ongoing assessment of the efficacy of numbering resource optimization measures prescribed by the Commission’s Numbering Resource Optimization (NRO) Orders. 2 Findings As of June 30, 2009: • Overall, 48.5% of all telephone numbers were assigned to end users. • The overall utilization rate for Incumbent Local Exchange Carriers (LECs) was 48.7%, down from 49.6% six months earlier. • The overall utilization rate for Cellular/PCS carriers was 66.1%, up from 65.6% six months earlier. • The overall utilization rate for Competitive LECs was 34.3%, up from 31.1% six months earlier. • Thousands-block pooling has made it unnecessary to distribute about 449 million telephone numbers. 1 The previous edition of this report, with data as of December 31, 2008, was released in September 2009. 2 See Numbering Resource Optimization, CC Docket No. 99-200, Report and Order and Further Notice of Proposed Rulemaking, 15 FCC Rcd 7574 (2000) (First NRO Order); Numbering Resource Optimization, CC Docket Nos. 99-200, 96-98, Second Report and Order, Order on Reconsideration in CC Docket No. 96-98 and CC Docket No. 99-200, and Second Further Notice of Proposed Rulemaking in CC Docket No. 99-200, 16 FCC Rcd 306 (2000) (Second NRO Order); Numbering Resource Optimization, CC Docket Nos. 99-200, 96-98, 95-116, Third Report and Order and Second Order on Reconsideration in CC Docket No. 96-98 and CC Docket No. 99-200, 17 FCC Rcd 252 (2001) (Third NRO Order); Numbering Resource Optimization, CC Docket Nos. 99-200, 96-98, 95-116, Fourth Report and Order in CC Docket No. 99-200 and CC Docket No. 95-116, and Fourth Further Notice of Proposed Rulemaking in CC Docket No. 99-200, 18 FCC Rcd 12472 (2003) (Fourth NRO Order). 3 • In the second quarter of 2009, carriers returned 1.15 million telephone numbers to the NANPA. • In the third quarter of 2009, carriers returned 0.82 million telephone numbers to the NANPA. Background The United States uses ten-digit telephone numbers, which are organized in accordance with the North American Numbering Plan (NANP). 3 The NANP divides the country into separate geographic areas called numbering plan areas (NPAs), more commonly called area codes. Calls between these areas are generally dialed using the three-digit area code, followed by a seven-digit local telephone number. When the NANP was established in 1947, only 78 area codes were assigned to carriers in the United States. Only 36 new codes were added through 1989. But the rate of activation increased dramatically. In the 1990s, 109 new area codes were activated in the United States. 4 Because the remaining supply of unassigned area codes is diminishing, and because a premature exhaust of area codes imposes significant costs on consumers, the Commission in 1999 initiated a proceeding to ensure that the limited numbering resources are used efficiently and thereby slow telephone number exhaust. In 2000 it issued its first NRO Order, in which, among other things, the Commission established the requirement that carriers submit data on numbering resource utilization and forecasts twice a year. The information is submitted using FCC Form 502, which is known as the Numbering Resource Utilization/Forecast (NRUF) form. 5 Carriers controlling numbering resources for the purpose of providing services to their customers are required to file their NRUF forms with the North American Numbering Plan Administrator (NANPA) 6 by February 1 and August 1 of each year. 7 The administrator compiles the information submitted into a database and provides that database to the Commission. 8 The NRUF-based information in this report presents number 3 The North American Numbering Plan is used in the United States and its territories, and in Canada, Bermuda, and many Caribbean nations, including Anguilla, Antigua and Barbuda, the Bahamas, Barbados, British Virgin Islands, Cayman Islands, Dominica, Dominican Republic, Grenada, Jamaica, Montserrat, St. Kitts and Nevis, St. Lucia, St. Vincent and the Grenadines, Trinidad and Tobago, and the Turks and Caicos Islands. The data contained in this report are all limited to the United States and its overseas territories. 4 NeuStar, Inc. publishes a database containing information about each area code on its website: http://www.nanpa.com/npa/allnpas.zip. 5 See Numbering Resource Optimization, CC Docket No. 99-200, Order, 15 FCC Rcd 17005, 17006, n. 9 (2000) (July 2000 NRO Order). FCC Form 502 and most other FCC forms can be downloaded via www.fcc.gov/formpage.html. 6 The current NANPA is NeuStar, Inc. 7 First NRO Order, 15 FCC Rcd at 7603, para. 67. 8 The NANPA’s database is continually updated because not all carriers file by the prescribed date, and because carriers sometimes file updated information throughout the year. 4 utilization as of June 30, 2009. It reflects all corrections and submissions that the NANPA received through November 1, 2009. 9 Historically, local telephone companies received geographic numbers in blocks of 10,000. These blocks of 10,000 numbers are often called NXXs, or central office codes, and are identifiable as the first three digits of a seven-digit telephone number. 10 One of the efforts to improve the efficiency with which numbers are used is “thousands-block number pooling,” where an NXX is broken into ten sequential blocks of 1,000 numbers. Carriers may then be required to donate unused or underutilized blocks to a pooling administrator, which then assigns those thousands-blocks to other carriers in need of numbers. 11 This effectively allows the assignment of numbers in blocks of 1,000 rather than 10,000. Most carriers are required to report their telephone number usage at the thousands-block level so that the Commission can evaluate the efficacy of telephone number pooling. Carriers that meet the statutory definition of “rural telephone company” 12 and operate in non-pooling areas are required to submit their number usage at the NXX level. In this report, we present utilization data for four types of carriers: 13 • Incumbent LECs • Competitive LECs • Cellular/PCS Carriers • Paging Carriers Carriers report on numbering resources in the following six categories: • assigned • intermediate • reserved • aging • administrative • available 9 Not all carriers filed their NRUF forms by the August 1, 2009 deadline. 10 A ten-thousands block is the block of 10,000 telephone numbers that have the same area code and the same NXX. 11 The current pooling administrator is NeuStar, Inc., which is also the NANPA. 12 47 U.S.C. § 153(37). 13 Carriers classified themselves in a variety of ways on their NRUF forms. With one exception, each carrier type was aggregated into one of these four categories for the purposes of this report. The exception involves carriers calling themselves interexchange carriers. These carriers reported data for area codes 500 and 900, which are summarized in Table 10 of this report. Therefore, there was no need to classify interexchange carriers as one of the four carrier types listed above. Also, carriers may provide multiple types of services, and may be doing so under a single operating company number. Where this occurs, this may cause a problem because carriers must indicate only their primary line of business on FCC Form 502. Thus, for example, there is some potential that some numbers are classified as cellular but are really used for paging. Only small carriers seem to do this, so the effects of this misclassification should be minor. 5 An assigned number is one that is in use by an end-user customer. Intermediate numbers are those that one carrier has made available for use by another carrier (or to a non-carrier) so that the numbers may then be assigned to an end user. Reserved numbers are those that are being held by the service provider at the request of an end user for future use. Aging numbers are those that are being held out of use by the carrier for a period of time after the end user that last used them discontinues service. Administrative numbers include test numbers and other numbers used for network purposes. Available numbers are numbers that are generally available for assignment to customers. 14 Some carriers receive telephone numbers from other carriers. When this occurs, the carrier that received its numbers from another carrier (as opposed to directly from the NANPA) is required to report utilization data for those numbers, and to mark those numbers as having been received from other carriers. 15 The vast majority of numbering resources reported were part of geographic area codes. That is, the numbers were part of area codes that are associated with specific regions of the United States or another country. For instance, area code 406 is associated with Montana, and area code 506 is associated with New Brunswick, Canada. Carriers are also required to report on utilization of some non-geographic area codes, such as 500 numbers and 900 numbers (which are described later in this report). Carriers use other types of non-geographic numbering resources as well: millions of numbers are used to provide toll-free services using non-geographic area codes such as 800, 888, 877 and 866. These numbering resources are managed separately. Analysis and Results Table 1 shows the total quantity of telephone numbers reported by the carriers and the number of 10,000 blocks (or NXXs) that were reported. Table 1 also shows the quantity of telephone numbers that carriers reported for each of the six categories described above. The percentages for each of the six categories are provided as well. Carriers reported usage data on 140,260 NXXs. This is up from the 140,189 NXXs from the previous filing (data for December 31, 2008). As the NANPA calculates that about 143,000 NXXs have been assigned to United States carriers, 16 this round of submissions (data for June 30, 2009) appears to have garnered usable information on 98% of the numbering resources 14 For precise definitions of these categories, see 47 C.F.R. § 52.15. 15 This means that sometimes more than one carrier can report utilization data for the same thousands-block (or ten-thousands block). Carriers receiving numbers from another carrier are required to report utilization data for those numbers on a different page (of FCC Form 502) than the page that carriers use to report numbers received directly from the NANPA. Not all carriers that received numbers from other carriers filed on the correct page, however, so within the database it can appear that more than one carrier has reported data for the same block of numbers. Carriers that receive numbers from other carriers are also required to report on any telephone numbers received from the NANPA. 16 The NANPA lists the codes that have been issued on their web site: http://www.nanpa.com/reports/reports_cocodes_assign.html. 6 assigned to carriers in the United States. Although the reporting level is high, many carriers still had not provided usable utilization data by November 2, 2009, the cut-off date for inclusion in this report. Carriers filing FCC Forms 502 reported that about 673 million telephone numbers were assigned to end users, and that 629 million were available for assignment. These 629 million available numbers do not include any telephone numbers in NXXs that had not yet been assigned to a carrier. As more NXXs are assigned to carriers by the NANPA, and more area codes are opened, more numbers will become available. Intermediate, reserved, aging and administrative categories collectively account for another 87 million telephone numbers of the NXXs assigned to carriers. The quantity of incumbent LEC assigned numbers is down slightly, reflecting the decreasing number of incumbent LEC lines. 17 The quantity of cellular/PCS assigned numbers is up, reflecting that sector’s growth. The quantity of CLEC assigned numbers continues to rise, in part, because of telephone service provided through voice over Internet protocol (VoIP). Table 2 presents utilization statistics for carriers reporting at the thousands-block level (carriers that do not meet the statutory definition of a rural carrier are required to report at the thousands- block level). Table 3 presents statistics for rural carriers, which are required to report only at the 10,000 block level. 18 As might be expected, overall utilization rates are lower in rural areas (about 15% of telephone numbers are assigned to end users) than in more urban areas (about 51% of telephone numbers are assigned to end users). Table 4 shows utilization statistics on a state-by-state basis. As might be expected, states that are relatively rural and have low population densities have a lower percentage of numbers that have been assigned to end-user customers than in more urban, populous states. Again, carriers report for only those numbers that have been assigned to them, so the quantity of available numbers does not include any of the NXXs that had not yet been assigned to a carrier. Table 5 shows the number of carriers reporting telephone number utilization data for each state. Carriers are required to report their NRUF data at the operating company number (OCN) level. 19 Carriers typically obtain one or more OCNs per state in which they operate. The number of carriers in each state is determined by counting the number of OCNs reported in each state. Table 6 shows utilization statistics on an area code-by-area code basis. The table also shows the total number of OCNs reported in each area code. Again, carriers report for only those numbers that have been assigned to them, so the quantity of available numbers does not include any of the NXXs in the state that had not yet been assigned to a carrier. 17 See Table 1 of the most recent Local Telephone Competition report at http://www.fcc.gov/wcb/iatd/comp.html. 18 See First NRO Order, 15 FCC Rcd at 7604-05, para. 71. A small number of rural carriers may operate in areas with pooling. As all carriers in pooling areas are required to report at the thousands-block level, rural carriers in pooling areas, if any, should be included in Table 2 rather than Table 3. 19 See First NRO Order, 15 FCC Rcd at 7594, para. 41. Carriers obtain OCNs from the National Exchange Carrier Association. 7 Table 7 shows actual quantities of assigned, aging and available numbers for wireline carriers (incumbent LECs and CLECs), and for cellular/PCS carriers (wireless carriers). This information is presented on an area code-by-area code basis. The information in Table 7 is useful for at least two reasons. First, while there is no information on the number of working telephone lines in each area code, Table 7 provides at least some indication of what these numbers are. For several reasons, however, the number of working lines per area code cannot be perfectly divined from this information. Although cellular/PCS carriers typically assign one geographic telephone number to each subscriber, wireline carriers sometimes do not. Some wireline customers want multiple telephone numbers associated with a smaller number of lines. This is common when the customer has a PBX. Other customers, especially those expecting many inbound calls, such as from a help line, want a single telephone number that serves many lines. Thus, the quantity of telephone numbers in an area code provides only a rough guide to the number of lines served in each area code. Second, the information in Table 7 provides the only information available for examining churn. 20 After a customer disconnects from a carrier’s network and chooses not to port the number to another carrier, that carrier will hold that number out of circulation (“age” the number) for up to ninety days if the customer was a residential subscriber, and up to one year if the customer was a business subscriber. Therefore, the quantity of aging numbers gives some indication of the number of customers that have disconnected from the carrier’s network in the previous three months to a year. For several reasons, aging numbers, however, do not give a perfect indication of churn. Aside from not measuring numbers ported to another carrier, not all carriers age their numbers for the full time allowed. In particular, where carriers cannot immediately obtain new numbers from the NANPA or the pooling administrator because of area code rationing, and the carriers have no other available numbers to assign to end users, carriers may assign end users telephone numbers that have not been aged for the full time that the states have prescribed. (Thousands-block pooling alleviates this problem by making more numbering resources available.) Moreover, as mentioned in the previous paragraph, wireline carriers do not always issue one telephone number per line. Thus, as with line counts, churn rates can only be roughly estimated from the data in Table 7. Table 8 focuses on telephone number pooling. A thousands-block is potentially poolable when 90% or more of the numbers are classified as available for assignment. Pooling is required in the top 100 MSAs. 21 Pooling also is occurring in other areas where a state commission has exercised delegated authority to require pooling. 22 Carriers also have voluntarily implemented pooling in certain areas. The Commission established an initial roll-out schedule for 20 Churn is the rate at which customers change carriers or disconnect service. 21 The composition of MSAs may change over time. If a rate center is part of a top 100 MSA at any time after 1990, then the FCC generally requires number pooling. See Fourth NRO Order, 18 FCC Rcd at 12473, para. 2. 22 Most recently, the Commission granted authority to the Idaho, Alabama and Wisconsin commissions to expand pooling to areas outside of the top 100 MSAs. See Numbering Resource Optimization; Implementation of the Local Competition Provisions of the Telecommunications Act of 1996, WC Docket 07-118, CC Docket Nos. 99-200, 96-98, Order, 22 FCC Rcd 16081 (2007). The Commission also has sought comment on whether it should delegate authority to all states to implement mandatory pooling at their discretion. See Numbering Resource Optimization, CC Docket No. 99-200, Order and Fifth Notice of Proposed Rulemaking, 21 FCC Rcd 1833 (2006). 8 thousands-block number pooling for wireline carriers, which was completed in December 2003. 23 Table 8 shows the number of thousands-blocks that carriers have received from the Pooling Administrator. Table 8 also shows the total number of thousands-blocks in rate centers where pooling exists, and shows the percentage of those thousands blocks that are pooled. Wireless carriers are listed separately from CLECs and incumbent LECs because wireless carriers started porting on November 24, 2003. Table 9 examines the efficacy of thousands-block pooling by showing the utilization of the thousands-blocks that were distributed by the Pooling Administrator and the utilization rate that would have resulted had whole NXXs been issued. 24 Overall, if whole NXXs had been issued instead of individual thousands-blocks, utilization within those blocks would have been 22%. With pooling, however, utilization was 65%, nearly a three-fold increase. Another way of measuring the benefit of pooling is examining the quantity of telephone numbers saved through pooling. With pooling, 231 million telephone numbers were distributed to carriers in pooling areas. Had there been no pooling, over 681 million telephone numbers would have been distributed to the carriers. Thus, about 449 million telephone numbers have been saved through thousands-block pooling. Table 10 shows utilization data for two specialized nongeographic area codes: 500 and 900. Area code 500 is used for “follow me” service, which, among other things, can be used to route an incoming call to different phone numbers, depending on the time of day. Area code 900 is used for information services where the caller is not charged the normal long distance rates set by the caller’s long distance carrier, but usually is charged much higher prices that are preset by the call’s recipient. Figures 1 through 4 focus on utilization rates as a function of the number of thousands-blocks that the carriers hold within a local geographic area. 25 We used rate centers as our measure of local geographic area because thousands blocks are assigned to carriers on a rate-center basis. 26 Carriers serving densely populated areas may need more than one thousands block (each thousands block contains one thousand numbers) to provide service. In these densely populated areas, carriers should generally be able to achieve higher utilization rates than 23 See The Common Carrier Bureau Announces The First Quarter Schedule For National Thousands-Block Number Pooling, CC Docket No. 99-200, Public Notice, 17 FCC Rcd 103 (2001). See also Numbering Resource Optimization, CC Docket No. 99-200, Order, 17 FCC Rcd 7347 (2002). 24 Calculating the utilization rate had whole NXXs been issued was a 4-step process: 1) the number of thousands-blocks that a carrier held in a rate center was determined; 2) that number was rounded up to the next ten, which is the number of thousands-blocks the carrier would have received if it had received whole NXXs; 3) the number in step 2 was multiplied by 1,000 to calculate the total quantity of telephone numbers the carrier would have had in the rate center; 4) the number of telephone numbers that the carrier actually has in that rate center is then subtracted from the quantity calculated in step 3. 25 For the purposes of these figures, the utilization rate is defined as the number of telephone numbers assigned to end- user customers divided by 1,000 (the number of telephone numbers in the thousands block). 26 A rate center is a geographic area used to determine distances and prices for local and long distance calls. 9 carriers serving less densely populated areas, where one thousands block (or in many rural areas, a whole NXX) may be used to serve just a few customers. Figure 1 shows average incumbent LEC utilization rates as a function of the number of thousands-blocks in a rate center held by a carrier. The points in the figures were calculated using a three-step process. First, thousands-blocks were grouped depending on the number of thousands-blocks held by a carrier within a rate center. Second, the number of thousands- blocks held in a rate center was rounded to the nearest ten, to help protect the confidentiality of the data. Third, the average utilization rates were calculated for each of the groups (i.e., from the group of 10 thousands-blocks per rate center through the group of 1,000 thousands-blocks per rate center). 27 For example, for all instances where a carrier reported from 5 to 14 (which round to 10) thousands-blocks in a rate center, the average utilization rate was calculated. A similar average utilization rate was calculated for all instances where, for a carrier in a rate center, the number of thousands-blocks in a rate center was rounded to 20, 30, and so on through 1,000. To preserve carrier confidentiality, some data points have been collapsed into a single data point. For example, if there were only two companies with 350 thousands-blocks in a rate center, and another two companies with 360 thousands-blocks in a rate center, those data points were collapsed. This way, no carrier-specific data are released. Figures 2 through 4 show the same information for Cellular/PCS carriers, CLECs, and paging carriers. Table 11 focuses on NPA-NXX assignment information. There are three different databases that contain sources of NPA-NXX assignment information: NANPA’s NRUF database, NANPA’s NANP Administration System (NAS) database of NPA-NXX assignments, and the Local Exchange Routing Guide (LERG). 28 For a variety of reasons, the databases are not identical. Timing is a large factor in the differences. For instance, during an area code split, a carrier will maintain both the old and new NPA-NXXs in its systems during the phase called permissive dialing. 29 After permissive dialing ends, the carrier should remove the old NPA- NXXs from its systems. During permissive dialing, some carriers report utilization data for both the old and the new NPA-NXXs. Further, some carriers may not remove the old NPA- NXXs from their systems promptly after permissive dialing ends, and may therefore report utilization data on both the old and the new NPA-NXXs. Also, carriers sometimes delay updating the LERG after an NPA-NXX has been removed from their switch or when the carrier has given the NPA-NXX back to the NANPA. Thus, the NRUF database, the LERG and the NANPA assignment database may not be identical. Table 11 shows the number of NPA-NXXs that appear in the three databases. Table 12 shows the percentage of numbers that have been assigned to end users over time. The utilization rate for incumbent local exchange carriers is slowly declining and cellular/PCS and 27 In order to prevent disclosure of proprietary information, we have grouped some individual data points into clusters so that the specific utilization data for individual carriers cannot be divined by comparing the individual plot points with other data sources. 28 The NANPA’s assignment information can be found online: http://www.nanpa.com/reports/reports_cocodes_assign.html. The analysis in Table 11 examines only those codes that NANPA marked “assigned” (i.e., this study does not examine those codes marked “protected”, “reserved”, “unassignable”, or “vacant”). The LERG is published monthly by Telcordia Technologies. 29 During permissive dialing, a phone number may be called by using either the old or the new NPA. 10 CLEC utilization rates are generally increasing. The utilization rate for paging continues to drop because the paging market is shrinking. Table 13 shows, on a quarterly basis, the number of NXX assignments made by the NANPA, the number of NXXs that have been returned to the NANPA, and the number of net NXX assignments to carriers. The table shows that fewer NXXs generally are being issued each quarter, and that carriers continue to return unneeded NPA-NXXs to the NANPA for reassignment. Tables 14 through 16 display information on telephone number porting. All telephone number porting information in this report is derived from the local number portability database, which was designed solely for the purpose of routing calls. 30 There are several reasons that the quantity of ported numbers in the database at any given time does not equal the sum of numbers ported in prior months. When consumers who have already ported their telephone numbers do so again, the porting database retains only the most recent porting activity for those numbers. Consumers can also port their numbers back to the original carrier. 31 When this happens, it is counted as a port even though the number drops out of the porting database. 32 Also, carriers sometimes port blocks of numbers to other carriers before reassigning them in the LERG. Once the numbers are reassigned, they can be dropped from the porting database. Table 14 shows, on a monthly basis, the quantities of telephone numbers that have been ported since wireless porting started on November 24, 2003. The table shows that most porting activity is intramodal, that is between two landline carriers or between two mobile carriers. Table 15 shows the quantity of telephone numbers in the porting database at the end of each quarter. Table 16 is based on ports in the database as of September 30, 2009, and shows the quarter in which the numbers were ported. Table 17 shows the number of ports in the database on a state-by-state basis, and Table 18 shows the number of carriers involved in porting on a state-by-state basis. Table 19 shows the percentage of assigned numbers that were ported. 33 Tables 20 through 24 show information about toll-free numbers in the North American Numbering Plan. AT&T introduced toll-free service in 1967. The Commission changed procedures for routing toll-free calls on May 1, 1993 to make toll-free numbers "portable." This change enabled customers to switch service providers yet still retain their toll-free numbers. Table 20 shows that, between 1993 and 2000, the quantity of assigned toll-free numbers grew rapidly: growing from 3.9 million in 1993 to 24.2 million in 2000. New toll-free 30 NeuStar, Inc. is the portability administrator. NeuStar operates seven different porting databases. Commission staff combines information from these databases into a single database. 31 When a customer who is using a ported number discontinues service entirely, the ported number also goes back to the original carrier. 32 Area code splits can cause a number that was at one time ported from Carrier A to Carrier B to appear to be reported from Carrier A to Carrier B, as the database record must be updated to reflect the new area code. When this happens, the old porting record also disappears from the database. 33 Paging carriers are not required to port numbers. 11 calling codes were opened to meet the demand. In March 1996, calling code 888 was placed into service. The third toll-free calling code (877) went into effect April 4, 1998, and the fourth toll-free calling code (866) went into effect July 29, 2000. As of September 30, 2009, there were about 26 million toll-free numbers assigned. Tables 21 through 24 show the growth of each individual toll-free code: 800, 888, 877, and 866, respectively. In the event that another toll-free code is needed, the 855 code would be opened. Database Service Management, Inc./Team DSMI, a subsidiary of Telcordia Technologies, Inc., maintains the Toll-Free Service Management System for the United States and Canada. Table 25 shows the current list of area codes, the state or territory they serve, and the month the code was opened. Table 26 shows area code assignments since January 1999, along with the month the code was added, and the code that served the area previously. Table 27 shows how dialing patterns differ from state to state. For instance, in some states, callers making local calls within an area code are required to dial only the 7-digit phone number. In other states, callers making local calls must dial the ten-digit phone number (area code plus the phone number). Finally, in some states, local callers must dial a “1” before dialing the area code plus the phone number. Each state’s public utilities commission (or public service commission) determines the calling pattern for each area code in their state. 34 For both local and domestic toll calls, there are two basic types of calls: those within an area code and those between area codes. Table 27 shows the dialing patterns for all four types of calls. The last column of Table 27 indicates whether all toll calls in that state require callers to dial a “1” before the telephone number. Additional Information Additional information too lengthy to include in this report is contained on the Commission’s website. 35 The first set of additional information lists the more than 3,000 filers. The list includes the service provider’s name, its parent name, and its OCN. The second set of information shows, by carrier type and by rate center, the number of assigned telephone numbers and the number of thousands blocks reported in that rate center. Some information has been redacted (asterisked out), to prevent the potential release of non-public data. The information also includes the Metropolitan Statistical Area/Primary Metropolitan Statistical Area in which the rate center resides. 36 34 The dialing patterns for area codes are listed in the area code database, which can be found at http://www.nanpa.com/area_codes/index.html. 35 This report and additional numbering information can be found at http://www.fcc.gov/wcb/iatd/number.html. All of the Industry Analysis & Technology Division’s reports are available on the web, and are conveniently categorized. See http://www.fcc.gov/wcb/stats. 36 The rate center’s V&H coordinates from the LERG were used to determine in which MSA/PMSA the rate center resided. If the rate center is not in an MSA/PMSA, then the MSA/PMSA variable is left blank. 12 The pooling information submitted by NeuStar is also available, and includes the NPA, NXX, X (block number), recipient carrier, date of assignment for the block and other information about the block. NeuStar submitted pooling data as of October 13, 2009. For consistency, only blocks with effective dates through June 30, 2009 were used in creating the tables for this report. Technical Details The following material provides technical details on the data and procedures used in this analysis. With respect to Tables 1 through 3, the reader should note that the number of unique NXXs for each carrier type does not add up to the total number of unique NXXs. 37 This occurs when multiple carriers report data for the same numbering resource. In addition, some carriers reported at the thousands-block level and other carriers reported at the NXX level for the same NXX. In the past, when numbers were transferred from an incumbent LEC to another carrier, these numbers were classified as “assigned” because those numbers could not be used elsewhere in the incumbent LEC’s own system. According to the Commission’s standardized definitions, however, these numbers are classified as “intermediate” numbers. It appears that some large carriers have not reported these numbers as intermediate numbers. Because, in many instances, we were unable to match submissions that report intermediate numbers with submissions that report numbers as being received from another carrier, we had to create filters to ensure that numbers were not double counted. Where a Regional Bell Operating Company (RBOC) has acquired a carrier with CLEC services in the RBOC's operating region, the numbering resources of the acquired CLEC that are in the RBOC's operating region are counted as incumbent LEC resources. Where the acquired CLEC provides services outside of the acquirer's operating region, the numbering resources are treated as CLEC resources. For ease of comparison, Figures 1 through 4 plot utilization rates only when there were 1,000 or fewer thousands-blocks in a rate center. Some incumbent LECs reported more than 1,000 unique thousands-blocks in a single rate center. The average utilization rates in these instances (where the carrier has more than 1,000 thousands blocks in a rate center) were the same as the instances where the carrier has just fewer than 1,000 thousands blocks in a rate center. Therefore, the figures show only the data where the carriers reported up to 1,000 thousands- blocks within a rate center. This allows a linear scale to be used. In some instances, we observed that some CLECs had a large number of thousands-blocks in a single rate center. Although most CLECs do not have enough end-user lines in a rate center to warrant having so many thousands-blocks in that rate center, there are at least two reasons that a CLEC would do so. First, some CLECs provide service to unified messaging services, such 37 In some instances, more than one carrier reported numbering utilization data for the same NPA-NXX. Tables 1-3 report on the number of unique NPA-NXXs that were reported by each carrier type and by the industry as a whole. 13 as e-fax. 38 These services use large quantities of numbers. 39 Also, VoIP providers generally obtain NANP telephone numbers for their customers by partnering with a local exchange carrier, such as a CLEC, through a commercial arrangement rather than obtaining them directly from a numbering administrator. * * * * We invite users of this information to provide suggestions for improved data collection and analysis by using the attached customer response form, e-mailing comments to craig.stroup@fcc.gov, john.vu@fcc.gov, or calling the Industry Analysis and Technology Division at (202) 418-0940 (for TTY, call (202) 418-0484). 38 Unified messaging services allow end users to receive multiple types of messages (such as voice mail and faxes) at one phone number. Typically, these messages are then digitized and e-mailed to the end user. Because the end user does not need to answer the call personally, the messages can be sent to any phone number in the United States. Thus, unified messaging service providers can operate efficiently by obtaining a large number of thousands blocks in a single rate center. 39 Carriers assigning numbers to unified messaging services are instructed to report numbers as “intermediate” until the numbers are assigned by the unified messaging service providers to end users. Some carriers have assigned large quantities of numbers to unified messaging services but may not have received information back from the unified messaging company as to whether those numbers had been assigned to end users. This may explain why some carriers reported dozens of NXXs in a single rate center, yet classified all those numbers as intermediate rather than assigned.

Carriers typically obtain at least one OCN per state in which they do business. Thus, carriers with multiple OCNs are counted multiple times. An exception was made for those RBOCs that have acquired a company with CLEC operations within their operating areas. Although the acquired CLEC's numbers have been treated as Incumbent LEC numbers throughout this report, the acquired CLEC's OCN was not counted as an Incumbent LEC OCN in-region. Where the acquired CLEC operates outside of the acquiring RBOC's operating area, the CLEC's OCN was counted as a CLEC. 2 Carriers occasionally misclassify the type of service that they provide. For instance, the CLEC operations of incumbent LECs are occasionally classified as incumbent LEC operations. 16 Table 6 Telephone Number Utilization by Area Code as of June 30, 2009 Area Code

Source: Raw data from Local Number Portability Administrator (NeuStar, Inc.).

These figures include all ports during the month of November, which for ports from or to a wireless carrier, includes a small number of test ports that happened prior to November 24. 4 Due to a data problem, figure does not include numbers that were ported back to the original carrier, or where the subscriber with the ported number terminated service. 2 Excludes significant porting activity between Cingular and AT&T Wireless following the closing of their merger in October 2004. 5 In late 2007, some wireline carriers completed plans to transfer groups of numbers to the wireless carriers that were providing service to end users using those numbers. In many cases, the whole block could not be reassigned in the LERG so number porting was used to effectuate the transfer. 35 Table 15 Telephone Numbers Remaining in the Porting Database at the End of Each Quarter 1 Wireline to Wireline to Wireless to Wireless to Total Year Quarter Wireline Wireless Wireless 2 Wireline (In Thousands) (In Thousands) 1999 Second 1,840 * * * 1,840 Third 2,658 * * * 2,658 Fourth 3,854 * * * 3,854 2000 First 5,029 * * * 5,029 Second 5,781 * * * 5,781 Third 7,595 * * * 7,595 Fourth 9,146 * * * 9,146 2001 First 10,567 * * * 10,567 Second 12,310 * * * 12,310 Third 14,610 * * * 14,610 Fourth 15,519 * * * 15,519 2002 First 16,810 * * * 16,810 Second 18,210 * * * 18,210 Third 19,862 * * * 19,862 Fourth 21,449 * * * 21,449 2003 First 22,781 * * * 22,781 Second 23,723 * * * 23,723 Third 24,796 * * * 24,796 Fourth 25,869 16 795 2 26,682 2004 First 28,462 173 2,686 3 31,324 Second 28,371 406 4,635 4 33,417 Third 29,396 667 6,874 9 36,945 Fourth 30,607 832 9,041 11 41,491 2005 First 32,399 1,001 10,860 16 44,276 Second 34,169 1,092 12,956 19 48,236 Third 36,013 1,201 14,804 23 52,041 Fourth 37,608 1,246 16,101 29 54,983 2006 First 40,194 1,272 17,577 34 59,077 Second 42,130 1,333 19,032 42 62,538 Third 43,743 1,407 20,509 46 65,705 Fourth 45,149 1,480 21,920 50 68,600 2007 First 46,761 1,541 23,518 50 71,870 Second 48,396 1,659 25,399 54 75,508 Third 3 50,222 2,057 27,068 116 79,463 Fourth 53,168 2,031 29,065 120 84,384 2008 First 55,095 2,075 30,605 127 87,902 Second 56,114 2,067 32,024 153 90,359 Third 57,217 2,175 34,089 156 93,637 Fourth 58,924 2,255 35,851 171 97,202 2009 First 60,609 2,353 37,663 177 100,801 Second 62,508 2,433 39,221 182 104,344 Third 64,333 2,539 40,522 181 107,576 2 Excludes significant porting activity between Cingular and AT&T Wireless following the closing of their merger.

All ports before then are considered to be wireline to wireline ports, even though some of those ports appear to involve wireless companies. A small but unknown number of wireless test ports were conducted before November 24, 2003. The remaining wireless-related ports appear to be artifacts of divining the carrier type through the use of the carrier's operating company number. 1 Numbers ported because customer changed carriers. The database contains the date when the telephone number record was last updated. For most telephone numbers, this was the most recent port. For those telephone numbers affected by area code changes, however, the date refers to when the record was updated to reflect the new area code See the text for a fuller discussion. 3 Starting with the July 2007 data, the method of determining whether a port came from a wireline or wireless carrier changed. For numbers that have been ported multiple times, the original carrier is now used to determine the porting carrier's type. Previously, the porting carrier's type was based on the most recent port. 36 Table 16 Numbers in the Porting Database by Quarter in Which They Were Most Recently Ported 1 September 30, 2009 2 Ported During Wireline to Wireline to Wireless to Wireless to Year Quarter Wireline Wireless Wireless Wireline (In Thousands) (In Thousands) 1998 First 0 3 * * * Second 3 * * * Third 36 * * * Fourth 106 * * * 1999 First 186 * * * Second 292 * * * Third 300 * * * Fourth 386 * * * 2000 First 410 * * * Second 468 * * * Third 581 * * * Fourth 650 * * * 2001 First 566 * * * Second 709 * * * Third 730 * * * Fourth 897 * * * 2002 First 753 * * * Second 855 * * * Third 1,011 * * * Fourth 846 * * * 2003 First 762 * * * Second 934 * * * Third 919 * * * Fourth 911 8 297 2 2004 First 1,251 107 656 2 Second 1,231 76 760 8 Third 1,268 156 911 7 Fourth 1,209 97 928 4 2005 First 1,471 75 917 4 Second 1,563 65 1,001 3 Third 1,782 86 1,163 4 Fourth 1,589 57 1,197 12 2006 First 2,312 47 1,183 4 Second 1,858 59 1,232 4 Third 1,660 105 1,430 5 Fourth 1,675 86 1,472 5 2007 First 1,809 83 1,479 5 Second 2,040 122 1,564 4 Third 2,549 223 1,947 22 Fourth 4,093 203 2,338 9 2008 First 2,815 66 4 2,225 8 Second 2,870 72 2,205 7 Third 3,012 121 2,977 7 Fourth 3,033 132 2,969 6 2009 First 3,052 127 2,974 8 Second 3,335 127 3,052 7 Third 3,572 236 3,645 9 1 The vast majority of these numbers are ported because customer changed carriers. 3 Number is between 0 and 499. Source: Raw data from Local Number Portability Administrator (NeuStar, Inc.). Rollups performed by the Industry Analysis and Technology Division staff, Wireline Competition Bureau. 2 The local number portability database was designed solely for the purpose of routing calls. As such, it retains only the most recent porting activity for any given number. So if a consumer ports a number from Carrier A to Carrier B, and later the consumer then ports the number from Carrier B to Carrier C, the database will not reflect the original port from Carrier A to Carrier B. Also, numbers that revert back to the original carrier (either because the customer ports the number back to the original carrier or because the customer discontinues service with that number) are dropped from the database. Lastly, area code splits can make a number appear to be ported later than it actually was. Starting with the previous edition of this report, the methodology for determining whether a number was ported away from a wireline or a wireless carrier changed. Rather than relying on the carrier type of the most recent port, the numbers now reflect the original carrier type, based on the carrier that is assigned the thousands block of the donated number. * Wireless portability started November 24, 2003.

Previously, the porting carrier's type was based on the most recent port. 39 Table 19 Percentage of Numbers Ported, as of June 30, 2009 1 Wireline Wireline Wireless Wireless Total Total Wireline Assigned Percent Wireless Assigned Percent Total Assigned Percent Ports Numbers Ported Ports Numbers Ported Ports Numbers Ported State (thousands) (%) (thousands) (%) (thousands) (%) Alabama 547 4,751 11.5 391 4,913 8.0 938 9,664 9.7 Alaska 162 907 17.9 241 636 37.9 403 1,544 26.1 American Samoa 0 0 NA 0 26 0.0 0 26 0.0 Arizona 1,450 8,052 18.0 780 5,295 14.7 2,230 13,348 16.7 Arkansas 356 2,664 13.4 117 2,424 4.8 473 5,087 9.3 California 8,927 47,802 18.7 4,616 33,997 13.6 13,543 81,799 16.6 Colorado 1,047 7,570 13.8 708 4,675 15.1 1,755 12,246 14.3 Connecticut 799 4,700 17.0 415 3,177 13.0 1,214 7,877 15.4 Delaware 331 1,810 18.3 87 841 10.3 417 2,652 15.7 District of Columbia 430 3,142 13.7 161 1,179 13.7 592 4,321 13.7 Florida 3,321 21,813 15.2 2,597 17,385 14.9 5,917 39,198 15.1 Georgia 1,695 10,895 15.6 1,060 8,548 12.4 2,755 19,443 14.2 Guam 1 90 1.6 6 129 4.8 8 219 3.5 Hawaii 219 1,588 13.8 185 1,245 14.9 405 2,832 14.3 Idaho 129 1,775 7.2 190 1,167 16.2 318 2,942 10.8 Illinois 2,658 17,505 15.2 1,646 11,716 14.0 4,303 29,221 14.7 Indiana 795 6,318 12.6 544 5,298 10.3 1,339 11,616 11.5 Iowa 309 4,644 6.7 244 2,451 10.0 553 7,095 7.8 Kansas 688 3,052 22.6 268 2,425 11.0 956 5,477 17.5 Kentucky 462 4,536 10.2 375 3,709 10.1 836 8,245 10.1 Louisiana 525 4,777 11.0 388 4,275 9.1 913 9,053 10.1 Maine 333 1,543 21.5 107 1,057 10.2 440 2,601 16.9 Maryland 1,052 9,357 11.2 772 5,529 14.0 1,824 14,886 12.3 Massachusetts 2,421 13,915 17.4 929 6,275 14.8 3,350 20,191 16.6 Michigan 2,194 10,806 20.3 1,484 9,848 15.1 3,678 20,653 17.8 Minnesota 1,354 7,404 18.3 791 4,568 17.3 2,145 11,972 17.9 Mississippi 182 2,545 7.2 168 2,462 6.8 350 5,007 7.0 Missouri 835 6,324 13.2 589 5,217 11.3 1,424 11,542 12.3 Montana 82 929 8.8 59 750 7.8 141 1,679 8.4 Nebraska 302 2,118 14.3 152 1,512 10.0 454 3,630 12.5 Nevada 577 3,259 17.7 285 2,464 11.6 863 5,723 15.1 New Hampshire 331 2,212 15.0 144 1,130 12.7 475 3,342 14.2 New Jersey 1,754 13,261 13.2 1,052 8,516 12.4 2,807 21,777 12.9 New Mexico 174 2,021 8.6 157 1,720 9.1 331 3,741 8.9 New York 5,181 26,578 19.5 2,653 19,179 13.8 7,834 45,758 17.1 North Carolina 1,391 10,555 13.2 890 6,776 13.1 2,281 17,331 13.2 North Dakota 78 643 12.1 44 553 8.0 122 1,197 10.2 Northern Mariana Is * 0 NA * 54 0.1 0 54 0.2 Ohio 1,893 13,131 14.4 1,334 10,250 13.0 3,227 23,380 13.8 Oklahoma 478 3,421 14.0 410 3,085 13.3 888 6,506 13.6 Oregon 713 4,527 15.7 479 3,182 15.0 1,192 7,710 15.5 Pennsylvania 2,678 17,010 15.7 1,520 11,241 13.5 4,198 28,251 14.9 Puerto Rico 81 1,561 5.2 345 2,106 16.4 426 3,667 11.6 Rhode Island 274 2,147 12.8 136 935 14.6 410 3,081 13.3 South Carolina 619 4,718 13.1 371 3,957 9.4 990 8,676 11.4 South Dakota 116 770 15.0 48 630 7.6 164 1,400 11.7 Tennessee 1,010 6,718 15.0 616 6,197 9.9 1,625 12,915 12.6 Texas 4,193 27,459 15.3 2,510 22,955 10.9 6,703 50,414 13.3 Utah 799 4,007 20.0 350 2,222 15.8 1,149 6,229 18.5 Vermont 118 1,881 6.3 31 465 6.7 149 2,346 6.3 Virgin Islands * 57 0.0 * 113 0.0 0 170 0.0 Virginia 1,526 11,176 13.7 954 7,430 12.8 2,480 18,606 13.3 Washington 2,364 9,851 24.0 834 5,917 14.1 3,198 15,768 20.3 West Virginia 185 1,493 12.4 190 1,239 15.3 374 2,732 13.7 Wisconsin 949 6,001 15.8 630 4,604 13.7 1,578 10,606 14.9 Wyoming 33 568 5.8 27 503 5.5 60 1,071 5.6 Total 61,121 388,358 0.2 36,081 280,156 0.1 97,202 668,514 14.5 1 Because the latest available NRUF data are as of December 31, 2008, porting data of the same vintage are used.

On May 1, 1993, procedures for routing toll- free calls were changed and 800 numbers were made "portable" so customers who switched service providers could retain their numbers. Due to the growth in demand for toll-free numbers, a new toll-free calling code, 888, was added in March 1996, which made it possible to assign about 8 million new toll- free numbers.
