How to Use the FCC Broadband Map
The FCC's National Broadband Map (broadbandmap.fcc.gov) is the most comprehensive public tool for checking broadband availability across the United States. Launched in 2022 with updated data collection requirements, it offers address-level coverage information for every ISP that has reported service to the FCC.
Here's how to use it effectively.
### Step 1: Navigate to the Map
Go to **broadbandmap.fcc.gov**. You'll see a map of the United States with color coding showing coverage levels. You can pan and zoom this map, but for specific addresses, use the search function.
### Step 2: Enter Your Address
In the search bar at the top of the map, type your full street address including the city and state. Be as specific as possible — include apartment or unit numbers for multi-family buildings.
The map will zoom to your location and display a marker at your address.
### Step 3: View Provider Results
After searching your address, the map will display a panel (usually on the left side of the screen) listing:
- **Available providers** at your location - **Technology type** for each provider (fiber, cable, DSL, fixed wireless, licensed fixed wireless, unlicensed fixed wireless, satellite) - **Maximum advertised download and upload speeds** for each provider/technology
Check What's Available at Your Address
See which fiber, cable, and wireless providers serve your location — independent and 100% free for consumers.
Check My Address### Understanding Technology Type Codes
The FCC uses specific technology type codes: - **Fiber** (Technology Code 50): Fiber-to-the-home or fiber-to-the-building - **Cable** (Technology Code 40/42): HFC coaxial cable - **DSL** (Technology Code 10/11/12): Digital Subscriber Line over copper phone lines - **Licensed Fixed Wireless** (Technology Code 70): Point-to-point or point-to-multipoint radio - **Unlicensed Fixed Wireless** (Technology Code 71): Wi-Fi based fixed wireless - **Satellite** (Technology Code 60/61): Geostationary (HughesNet, Viasat) or LEO (Starlink) - **Terrestrial Fixed Wireless** (multiple codes): Various wireless technologies
Technology type matters because a satellite provider can show as "serving" nearly every US address — but satellite is fundamentally different from wired broadband. Look specifically for fiber, cable, or fixed wireless options before concluding satellite is your only choice.
### Step 4: Download Speeds Tab
The map has a "Download Speeds" view that color-codes areas by the fastest available download speed, regardless of technology or provider. This is useful for a quick visual assessment of coverage quality in a region.
### Step 5: Filing a Challenge
If the map shows your address as "served" but you know that service isn't actually available:
1. Look for the "Challenge" button near your address result 2. Select the provider whose coverage claim you're disputing 3. Choose the reason for the challenge (e.g., service not available, speeds are lower than reported) 4. Provide supporting documentation if possible (ISP response denying service, etc.) 5. Submit the challenge
Approved challenges update the map and can affect whether your address qualifies for federal funding programs like BEAD.
### Step 6: Check the "Availability by Location Fabric" Tab
The map provides more granular data in its underlying fabric. Each address in the US has been assigned to the FCC's "location fabric" — a comprehensive database of all broadband-serviceable locations. Searching your address accesses this underlying data.
### Limitations to Know
The map reflects ISP self-reported data, which may be inaccurate. ISPs sometimes claim coverage at addresses they don't actually serve. Always verify claimed availability directly with the ISP before making decisions.
Satellite providers (Starlink, HughesNet) show as available at virtually every US address, which can make underserved areas appear better-served than they are for wired broadband purposes.
### Using the Map for Advocacy
If you're working to bring better broadband to your community, the FCC map provides data you can use with your state broadband office, county officials, and potential providers to document coverage gaps and demonstrate need.
