How do I file?

  • Filers will submit data in the BDC system either via file upload or web form.

Important information for filers of FCC Form 477

The Commission has announced the sunset of the block-level broadband deployment data required on FCC Form 477. All remaining information required for Form 477, and all information required for the Broadband Data Collection, must be filed in the BDC system going forward. See “What do I need to file?” above for information on the filing requirements by provider type.

Service providers that offer only fixed voice service (and do not also offer broadband service) must similarly submit their fixed voice subscribership data in the BDC system. The Form 477 filing interface will not accept data as of December 31, 2022.

See the BDC Availability Data Specifications for information on the data required by the BDC system. For information on revising previously submitted Form 477 data, see the FCC’s Form 477 Resources page.
