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. NTIA built upon existing partnerships to identify data from federal, state, local and tribal governments, owners and operators of broadband networks, 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 FCC, U.S. Census Bureau, Universal Service Administrative Company, U.S. Department of Agriculture, Ookla, Measurement Lab, and the state governments. Users, including administrators from 22 participating states, access the NBAM mapping platform and use these data resources to better inform broadband projects and funding decisions in their states. 

Updated Information on Participating States:

On July 23, 2020, NTIA announced the addition of two states to its National Broadband Availability Map (NBAM) program. Indiana and Georgia join 20 other states who are partnering on this critical broadband data platform. These states include California, Colorado, Illinois, Maine, Massachusetts, Michigan, Minnesota, Missouri, Nebraska, New Hampshire, New Mexico, North Carolina, Oregon, Tennessee, Utah, Virginia, Washington, West Virginia, Wisconsin, and Wyoming.  With this addition, the NBAM is another step closer to creating a national platform that can help inform policymakers and expand Internet coverage across the United States.
