Federal Communications Commission DA 25-1081 DA 25-1081 Released: December 18, 2025 INTERIM REQUIRED LOCATIONS LISTS POSTED FOR THE RURAL DIGITAL OPPORTUNITY FUND AND FINAL LOCATION LISTS POSTED FOR THE BRINGING PUERTO RICO TOGETHER FUND AND THE CONNECT USVI FUND WC Docket Nos. 10-90, 18-143, 19-126, 20-34 The Wireline Competition Bureau (Bureau) announces that the interim required locations lists for the Rural Digital Opportunity Fund (RDOF) and the final required location lists for the Bringing Puerto Rico Together (PR) Fund and the Connect USVI Fund are available here, https://www.fcc.gov/wireline-competition/HUBB-Transition. Carriers receiving support from these programs must transition to reporting Universal Service Fund High Cost program supported broadband deployment using Broadband Serviceable Location (BSL) Fabric IDs in the High Cost Universal Broadband (HUBB) portal. To learn more about the Fabric visit: https://help.bdc.fcc.gov/hc/en-us/articles/5375384069659-What-is-the-Location-Fabric More information about the transition is available here, https://www.fcc.gov/wireline-competition/HUBB-Transition. See Wireline Competition Bureau Provides Guidance to Rural Digital Opportunity Fund, Bringing Puerto Rico Together Fund, and Connect USVI Fund Carriers on the Transition to Reporting Fabric Location IDs in the High Cost Universal Broadband Portal, WC Docket Nos. 20-34, et al., Public Notice, 40 FCC Rcd 2881 (WCB 2025). If an RDOF carrier defaulted early on a census block group (CBG), the Location Fabric IDs for the BSLs within the defaulted CBGs will not be included in the RDOF carrier’s interim list. However, the RDOF carrier will still be subject to support recovery for the BSLs within the defaulted CBGs pursuant to section 54.806(c) of the Commission’s rules. 47 CFR § 54.806(c). The Universal Service Administrative Company will notify carriers when the updated lists are available in the HUBB for reporting. Support totals and location obligations for PR Fund and Connect USVI recipients will be adjusted to reflect the data in their final required location lists, which were created using the December 2025 Fabric dataset. Connect America Fund et al., WC Docket No. 10-90 et al., Order, 40 FCC Rcd 281, 305-07, paras. 57-62 (WCB 2025) (High-Cost Fabric Order). In the High-Cost Fabric Order, the Bureau adopted a process for implementing these support and location obligations adjustments for PR Fund and Connect USVI recipients based on the Fabric. Id. Specifically, PR Fund and Connect USVI recipients will be required to certify that they have reviewed the Fabric and identify whether there are more or fewer locations identified in the December 2025 Fabric than their original estimated location total. Id. at 305, para. 57. The Bureau expects to open a filing window for this process early next year. A future public notice will provide additional information about the process. We remind RDOF carriers that their final obligations will be determined using the December 2026 Fabric dataset. Id. at 291-92, para. 25. The December 2026 Fabric (Version 10) dataset will also be used for filing availability data as of December 31, 2026 in the FCC’s Broadband Data Collection. RDOF carriers should review their interim location lists and submit Fabric challenges to address any inaccuracies. For additional information on how to submit Fabric challenges visit: https://help.bdc.fcc.gov/hc/en-us/sections/8772050917659-Fabric-Challenges. Challenges filed by September 1, 2026 have the best opportunity to be reviewed and incorporated into the December 2026 Fabric. We highly encourage RDOF carriers to file Fabric challenges as soon as possible to have the best chance of having their challenges resolved in time. Outstanding or pending challenges that were filed but not incorporated in the December 2026 Fabric will not be considered for determining final RDOF carrier deployment obligations. High-Cost Fabric Order, 40 FCC Rcd at 291-92, para. 25. The Commission is working on additional support resources that will be made available through the Broadband Data Collection (BDC) Help Center. Please visit https://help.bdc.fcc.gov/hc/en-us regularly for updates and new support resources. Providers who are already licensees of the Fabric will receive an email later this month from CostQuest, the FCC’s Fabric contractor, providing them with links to access the December 2025 Fabric data. Providers that have not yet entered into a license agreement with CostQuest for Fabric data may do so by following the instructions for obtaining access to the Fabric in the BDC Help Center.
