How to Use the FCC’s National Broadband Map

The National Broadband Map displays where internet services are available across the United States, as reported by Internet Service Providers (ISPs) in the FCC’s ongoing Broadband Data Collection. The map allows consumers and other stakeholders to easily dispute, or challenge, information shown on the map that they believe is inaccurate.

To view the map, visit BroadbandMap.FCC.gov

From the home page, you can…

  • Enter an address into the Search by Address window to zoom to that location on the map. You can see a list of ISPs that can serve that location and other information including the types of technologies and speeds offered.
  • Pan, zoom, and explore the full map by clicking Location.
  • See where particular ISPs make broadband internet service available by clicking Providers.
  • Check out internet service availability and characteristics in your state, county, congressional district, census place (town), Tribal area, or CBSA (metro area) by clicking Area,
  • Save the data to your device by clicking Download.

Find an Address

Start by entering a street address into the Search by Address bar.  As you type, a list of addresses will begin to display below the search bar.  If the address you enter is included in the FCC’s database of locations, then the address will appear in CAPITAL LETTERS below the search bar.

If you don’t have a street address, you can enter a town name and state, or select “Location” underneath the search bar on the home page.  You can then zoom on the map to find a particular location.

What Are the Location Points?

When you zoom in on the map, you will see individual location points.  These points identify buildings or structures – such as a home, apartment or condo building, or small business building – where internet service is, or could be, available. 

  • Green locations have internet services available to them, based on information reported by an ISP.
  • Red locations have no reported internet services available.
  • Gray locations represent buildings or structures that are not likely to use the broadband internet access services typically sold to homes and small businesses (they typically use special commercial-grade broadband services).
  • Purple locations indicate that you are viewing the mobile coverage map.

How to Help Improve the Map

You can help the FCC improve the data on the map by submitting a challenge or requesting a correction, in one of the following ways:

  • Availability Challenges: If the information about the internet services available at your home or other location is incorrect, you can dispute it by clicking on the Availability Challenge link on the righthand side of the map and submitting the form.
  • Mobile Availability Challenges: If you are not receiving the mobile coverage shown for your provider on the map, you can dispute that information by taking outdoor or in-vehicle speed tests on your mobile device with the FCC’s Speed Test App, available for both Android and iOS. Make sure to select the app’s Challenge speed test option and to take the tests while either outdoors or in a vehicle; do not take the tests indoors.
  • Location Challenges: If the information on the map about the location point of your home or small business seems to be is incorrect or missing, you can submit a Location Challenge to correct or add the location. The link to do this is to the right of the address on the map.

Fixed and Mobile Maps

The map displays, by default, information on the “fixed” broadband services – these are the services offered to homes, small businesses, and certain other locations using wired, fixed wireless, and satellite technologies.  If you want to view a map showing “mobile” or cellular broadband coverage select the Mobile Broadband tab on the upper right-hand side of the page.

  • The Fixed Broadband Map shows the fiber, cable, DSL, satellite, or fixed wireless internet services available at each home or small business on the map. When you select a location, you can see which providers report offering broadband service at that location, and the types of service and the maximum advertised download and upload speeds they each offer.  Services with download speeds below 25 Mbps are not shown on the default map, but can be found by using the filtering function described below.
  • The Mobile Broadband Map shows the 3G, 4G, and 5G coverage of each mobile provider for the area displayed. The coverage areas reflect where consumers should be able to connect to the mobile network when outdoors or in a moving vehicle; they do not show indoor coverage. The map also allows you to compare mobile wireless coverage reported by wireless different mobile providers.

Filtering

You can filter the information displayed on the map by clicking on Settings blobid1.pngon the right side of the page.  To access Settingsblobid1.pngyou may need to expand the right sidebar by clicking the black arrow in the upper righthand corner of the map.

  • On the Fixed Broadband Map, you can choose from a list of technologies (DSL, cable, fiber, fixed wireless, and satellite) and a list of maximum advertised download/upload speed You can also select to display only business or only residential locations.
  • On the Mobile Broadband Map, you can choose to view 3G, 4G, and two levels of 5G coverage (35/3 Mbps or above and 7/1 Mbps or above). You can also choose to view outdoor stationary or in-vehicle mobile coverage.

You can also view different layers on the map to change the base map view or to view locations that have been challenged.  To do this, click on Toggle Layerson the left side of the page.    You can then select a different base map to display (Streets (Dark), Streets (Light), or Satellite) and/or select whether to view challenged locations (Location Challenge – blue circle around the point, Missing Location – purple circle around the point, or Availability Challenge – yellow circle around the point.
