How to prepare for BDC & HUBB filings

Below is a quick breakdown of the key filing deadlines, requirements, and other critical information to help you prepare your filings for the FCC’s Broadband Data Collection (BDC) and USAC’s HUBB portal. Save time fulfilling your reporting obligations and mitigate audit risk.

FCC Broadband Data Collection & USAC HUBB Reporting Obligations

FCC’s Broadband Data Collection

The Broadband Data Collection (BDC) program will supply the FCC, communications industry, state, local and Tribal government entities, and consumers the tools they need to improve the accuracy of existing broadband maps. All facilities-based broadband providers are required to file data with the FCC twice a year. The FCC released the official requirements for filings submitted into the Broadband Data Collection (BDC). Below is a breakdown of the new BDC filing requirements:

USAC’s HUBB portal

Providers participating in modernized funds must file deployment data with the High Cost Universal Broadband portal (HUBB), showing where they are building out mass-market, high-speed Internet service using CAF & RDOF support. Below is a breakdown of the HUBB filing requirements:

Broadband Data Collection filing requirements:

Who has to file?

  • Providers of fixed and mobile broadband Internet access who have one or more end users in service on June 30, 2022.
  • If you are required to file FCC Form 477 you must also submit data into the BDC

See more details for BDC filers.

Who else can file? 

  • Federal agencies, state, local, and Tribal governmental entities in charge of mapping or tracking broadband internet access service coverage in their areas, can submit verified availability data as of June 30, 2022.
  • Third parties who want to submit verified broadband availability data as of June 30, 2022.
    • These parties can also submit data as part of the BDC challenge and crowdsource processes.

What do I need to file? 

  • Your BDC filing should include information about the filer, broadband availability data (including supporting data), and – for broadband providers – Form 477 broadband subscription data.

  • Fixed wireline and satellite broadband service providers must submit either polygon shapefiles or a list of locations that fall in the provider’s service area.
  • Fixed wireless service providers need to submit either propagation maps and propagation model details or a list of locations that are in the provider’s service area.

  • Mobile broadband service providers must submit propagation maps and propagation model details for each network technology and for both outdoor stationary and in-vehicle mobile network coverage. They also need to:
    • Submit signal strength heat map data
    • File BDC mobile voice availability data

See BDC Availability Data Specifications for more filing details.

How do I file?

  • You will either submit data in the BDC system via file upload and/or web form or submit data using an Application Programming Interface (API).
  • A system user guide, instructions on how to use the optional API (application programming interface), and other technical assistance resources to assist filers will be provided soon.

Important information for Form 477 filers

Important info:

Currently, providers of broadband internet access service must file both the FCC Form 477 and the data required for the Broadband Data Collection.

Until the Commission announces a closing date for Form 477, fixed and mobile service providers that file in Form 477 are required to file deployment data in both the new BDC and the existing Form 477 filing systems.

Service providers that offer only fixed voice service need to submit fixed voice subscribership data only in the Form 477 filing system. When Form 477 closes, this data should be submitted into the BDC system.

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

HUBB filing requirements:

1. File deployment data into the HUBB – Submit geocoded locations from previous deployment year

2. Certify data by filing Form 481

3. Submit 54.314 certification

4. Submit performance measure testing

Keep in mind:


View USAC’s Annual Requirements for more details on filing requirements.

See guidelines for submitting data into USAC’s HUBB Portal.

HUBB filing deadline:

March 1, 2022

Participants in the following funding programs have until March 1, 2022 to file data for all locations deployed with CAF support in 2021 or certify that they have “no locations to upload.”

View USAC guidelines for more information about HUBB requirements.
