Federal Communications Commission DA 25-1080 DA 25-1080 Released: December 18, 2025 BROADBAND DATA TASK FORCE ANNOUNCES OPENING OF EIGHTH BROADBAND DATA COLLECTION FILING WINDOW AND FABRIC CHALLENGE DEADLINE WC Docket Nos. 11-10, 19-195 By this Public Notice, the Broadband Data Task Force (Task Force) announces that the eighth Broadband Data Collection (BDC) filing window for submitting broadband availability and other data as of December 31, 2025, will open on January 2, 2026. The Task Force also announces that the deadline for Fabric challenges to be considered for inclusion in the June 2026 update of the Fabric is March 2, 2026. Beginning on January 2, 2026, facilities-based broadband service providers may begin to submit data into the BDC system at https://bdc.fcc.gov/, specifying where they made mass-market broadband Internet access service available as of December 31, 2025. Establishing the Digital Opportunity Data Collection; Modernizing the FCC Form 477 Data Program, WC Docket Nos. 19-195, 11-10, Third Report and Order, 36 FCC Rcd 1126, 1130-31, 33-34, paras. 10-11 & n.42, 16-17 (2021). Facilities-based broadband providers must have one or more end-user connections in service. The Broadband DATA Act requires the Commission to collect broadband Internet access service data from each “provider of fixed or mobile broadband Internet access service.” Broadband Deployment Accuracy and Technological Availability Act, Pub. L. No. 116-130, 134 Stat. 228 (2020) (codified at 47 U.S.C. §§ 641-646), § 641(11). See Broadband Data Task Force and Office of Economics and Analytics Announce Inaugural Broadband Data Collection Filing Dates, Public Notice, DA 22-182 (BDTF/OEA Feb. 22, 2022). Such entities, as well as providers of fixed and mobile voice services, must also submit their December 31, 2025, subscription data required as part of Form 477 into the BDC system at https://bdc.fcc.gov/. While broadband providers are no longer required to file broadband deployment information using FCC Form 477, we remind them that they must also continue to file Form 477 subscribership and voice service availability data in the BDC system at https://bdc.fcc.gov/. All availability and subscription data must be submitted no later than March 2, 2026. Providers are required to submit broadband availability data for all locations where, as of December 31, 2025, they have a subscriber or can otherwise provide fixed broadband service within 10 days at a standard installation charge, or, in the case of mobile service providers, maps depicting their mobile broadband coverage area(s) as of that date. These availability data must include locations or areas that were previously removed through the challenge, verification, or audit processes if the provider claims that broadband service was available at such locations or areas as of December 31, 2025. We note, however, that data demonstrating the availability of service to support restoring such locations or areas to the National Broadband Map will not be collected during the upcoming filing window. As stated in the Commission’s Fourth Report & Order, Declaratory Ruling, and Further Notice of Proposed Rulemaking, the Broadband Data Task Force, together with the relevant Bureaus and Offices, will conduct a notice and comment process seeking input on what types of technology-specific data would support restoring a location or area that was previously removed from the Map.

A recorded webinar demonstrating how to use the BDC system is available at the “Education” tab at https://www.fcc.gov/BroadbandData/resources. More information on how to log in, navigate the BDC system, and submit data can be found in the BDC System User Guide. Related video tutorials and help articles are available in the BDC Help Center at https://www.fcc.gov/BroadbandData/Help. Information about the categories of broadband providers that must file availability data, the types of entities that may submit verified availability data, and what data must be filed can be found at https://www.fcc.gov/BroadbandData/filers. The Fabric serves as the foundation for the collection of fixed broadband availability data in the BDC. The updated Fabric is being made available to Fabric licensees and must be used by filers of fixed broadband availability for reporting their availability data as of December 31, 2025. Providers who are already licensees of the Fabric and all other Fabric licensees (including state, local, and Tribal government and other third-party entities) will receive an email from CostQuest, the FCC’s Fabric contractor, providing them with links to access the December 2025 Fabric data. Entities that have not yet entered into a license agreement with CostQuest for Fabric data (including broadband service providers, state, local, or Tribal governmental entities, or other entities wishing to use the Fabric data for purposes of participating in the BDC or non-commercial academic/public policy broadband research) may do so by following the instructions for obtaining access to the Fabric in the BDC Help Center. Information about the Fabric and how broadband service providers, governmental entities, and third parties can access it may be found in the BDC Help Center at https://www.fcc.gov/broadbanddata/fabrichelp. The new version of the Fabric incorporates data from updated data sources and other improvement efforts conducted by the FCC and CostQuest, as well as the results of Fabric challenges submitted by state, local, and Tribal governments, broadband service providers, and the public through the National Broadband Map. Changes from previous versions of the Fabric include additional Broadband Serviceable Locations and corrections to addresses, unit counts, building types, land use, and geographic coordinates. Information about the Fabric and methodology can be found at https://www.fcc.gov/BroadbandData/resources by clicking on “key reference documents.” In order to be reviewed ahead of the next update of the Fabric in June 2026, fabric challenges must be submitted no later than March 2, 2026. We encourage filers to submit their availability data as of December 31, 2025, as early as possible in the filing window. This will give filers an opportunity to address any problems with their data identified by the BDC system with time to make any necessary corrections in advance of the March 2, 2026, deadline. Failure to timely file required data in the new BDC system may lead to enforcement action and/or penalties as set forth in the Communications Act and other applicable laws.
