Public Maps & Data

Please note the Indicators of Broadband Need application and the Community Reports have been archived and are no longer available. Both applications are based on the FCC Form 477 for broadband availability. The FCC discontinued Form 477 on Dec. 31, 2022, and transitioned to the new Broadband Data Collection which identifies broadband availability based on broadband serviceable locations (BSLs). NTIA has retired the FCC Form 477 based applications. New NTIA mapping applications based on the broadband data sources currently available from the FCC and other sources can be found on

NTIA Public GIS Data

The National Telecommunications and Information Administration (NTIA) has developed a public data site to help our partners and the public to discover geospatial data published by NTIA. Data is available through the National Broadband Availability Map (NBAM) and includes data, web maps, and applications covering grant awards from NTIA.

The NTIA Public Data site includes dashboards and geospatial data for the following programs: Broadband Infrastructure Program, Tribal Broadband Connectivity Program, and Connecting Minority Communities Pilot Program. NTIA will add additional programs and respective data as awards are made and as the programs evolve.

National Broadband Availability Map

The National Telecommunications and Information Administration (NTIA) received funding from Congress in 2018 to update the National Broadband Availability Map (NBAM) in coordination with the Federal Communications Commission (FCC). Congress directed NTIA to acquire and utilize data from available third-party datasets that would create a platform to better understand broadband availability, adoption, and use. In the development and execution of the NBAM, NTIA built upon existing partnerships to identify and incorporate data from federal, state, local and tribal governments, broadband network owners and operators, educational institutions, nonprofits, and cooperatives to create the map.

The NBAM is a GIS platform used to visualize and analyze federal, state, and commercial broadband data sets. This includes data from the Appalachian Regional Commission (ARC), the Bureau of Indian Affairs (BIA), the Economic Development Administration (EDA), the Minority Business Development Agency (MBDA), U.S. Census Bureau, Federal Communications Commission (FCC), U.S. Department of Agriculture (USDA), U.S. Department of the Treasury, Ookla, Measurement Lab, BroadbandNow, White Star and the state governments. Users, including administrators from 50 participating states, five territories, and seven federal agencies, access the NBAM mapping platform and use these data resources to better inform broadband projects and funding decisions in their states.

NTIA’s National Broadband Availability Map (NBAM) includes 50 state participants, and five territory participants: Alabama, Alaska, American Samoa, Arizona, Arkansas, California, Colorado, Commonwealth of the Northern Mariana Islands, Connecticut, Delaware, Florida, Georgia, Guam, Hawaii, Idaho, Illinois, Indiana, Iowa, Kansas, Kentucky, Louisiana, Maine, Maryland, Massachusetts, Michigan, Minnesota, Mississippi, Missouri, Montana, Nebraska, Nevada, New Hampshire, New Jersey, New Mexico, New York, North Carolina, North Dakota, Ohio, Oklahoma, Oregon, Pennsylvania, Puerto Rico, Rhode Island, South Carolina, South Dakota, Tennessee, Texas, Utah, US Virgin Islands, Vermont, Virginia, Washington, West Virginia, Wisconsin, and Wyoming.

The NBAM has public data which is available on the NTIA Public Data site. To access non-public data, you will need to login to the NBAM as a state, Federal, or Tribal partner here:

Q: What is the National Broadband Availability Map (NBAM)?

A: The NBAM is a secure GIS (geographic information system) platform and data analytics tool for the visualization and comparison of federal, state, and commercially available data sets. The NBAM will help identify regions with insufficient service, compare multiple datasets to identify discrepancies in broadband availability (e.g., served vs. underserved or unserved), and can produce reports and analyses to support broadband policy, planning, and investment decision-making.

Q: Will the platform be available to the public?

A: The platform includes both publicly available and non-public data.  Non-public data may be business sensitive or have licensing restrictions that prevent public disclosure. Therefore, the NBAM is only available to state, tribal, and federal partners that have signed Joint Project Agreements or Memorandum of Understanding with NTIA for access to the NBAM.

Q: How does NTIA's National Broadband Availability map differ from the FCC National Broadband map?

A: The FCC National Broadband map includes information collected from the FCC’s Broadband Data Collection and determines broadband serviceable locations (BSL) for the country. NTIA's National Broadband Availability map includes the FCC data and other federal and non-federal datasets that can be compared to inform broadband planning and policy-making.  As the program moves forward, NTIA plans to add additional data from additional partner states, federal agencies, industry, and accessible commercial datasets.

Q: Whom should I contact for more information?

A: NBAM users should direct all inquiries, questions, suggestions and feedback to NTIA at Media and press inquiries should be directed to NTIA’s Office of Public Affairs at
