 PUBLIC  NOTICE  Federal  Communications  Commission  445  12th  St.,  S.  W.  Washington,  D.  C.  20554 
 DA  01-  1409 
 Released:  June  11,  2001 


 COMMON  CARRIER  BUREAU  CLARIFIES  THAT 
 FUTURE  FILINGS  OF  NUMBERING  UTILIZATION  AND 
 FORECAST  REPORTS  MUST  INCLUDE  NUMBERING 
 RESOURCES  IN  THE  500  AND  900  NPAs 


 CC  Docket  99-  200 
 On  March  31,  2000,  the  Commission  released  a  Report  and  Order  and  Further  Notice  of 
 Proposed  Rulemaking  that,  among  other  things,  required  carriers  to  report  semiannually  on  their 
 actual  and  forecasted  number  usage.  1  Carriers  are  required  to  file  reports  twice  each  calendar  year 
 on  or  before  February  1  for  the  six-  month  period  ending  December  31  and  on  or  before  August  1 
 for  the  six-  month  period  ending  June  30.  2 


 Carriers  that  receive  central  office  codes  or  NXX  codes  (i.  e.,  code  holders)  from  the 
 North  American  Numbering  Administrator  (NANPA),  or  that  receive  thousands-  blocks  (i.  e., 
 block  holders)  from  a  Pooling  Administrator,  must  report  utilization  and  forecast  data  for  all 
 numbering  resources  in  their  inventory  or  “assigned  to  them”,  including  numbering  resources  in 
 the  500  and  900  area  codes  or  numbering  plan  areas  (NPAs).  In  previous  numbering  utilization 
 and  forecast  reports,  carriers  have  not  included  information  on  the  500  and  900  NPAs.  Because 
 the  NANPA  has  reported  that  the  500  and  900  NPAs  are  nearing  exhaust,  it  is  necessary  to  more 
 closely  track  the  use  of  500  and  900  numbering  resources  and  more  closely  monitor  their 
 projected  exhaust.  Moreover,  the  NRO  Order  mandated  that  “all  carriers  that  receive  numbering 
 resources  from  the  NANPA  (i.  e.,  code  holders),  or  that  receive  numbering  resources  from  a 
 Pooling  Administrator  in  thousands  blocks  (i.  e.,  block  holders),  report  forecast  and  utilization 
 data  to  the  NANPA.”  3  Clearly  500  and  900  NPA’s  are  covered  by  this  mandate. 


 The  Bureau  has  instructed  the  NANPA,  in  accordance  with  47  C.  F.  R.  §  52.15  (g)(  3)(  4), 
 to  withhold  numbering  resources  from  carriers  that  fail  to  comply  with  these  reporting 
 requirements.  Carriers  are  encouraged  to  report  numbering  resources  in  the  500  and  900  NPAs

 separately  from  those  in  the  geographic  NPAs.  The  NANPA  will  provide  further  guidance  to 
 carriers  completing  utilization  and  forecast  data  for  500  and  900  numbering  resources  on  its  web 
 site,  www.  nanpa.  com.
