  • Redwood City – High-speed, high-quality internet service is essential for participation in modern life. The Federal Communications Commission has a map showing where internet service is – and is not – available across the country, including in San Mateo County.

    The FCC requires internet service providers to report where they make internet services available. The FCC reviews the data and then publishes it on the National Broadband Map.

    You can easily dispute, or challenge, information shown on the map that you believe is inaccurate.

    An accurate map will help identify the unserved and underserved communities most in need of funding for high-speed internet infrastructure investments.

    What You Can Do:


    Find Out What Internet Services Are Available in Your Area
    Search for your address on the map. If you don’t have an address, you can enter a town name and state, or select “Location” underneath the search bar on the home page. The map allows you to pan and zoom to find a particular location.

    Help Improve the Map:
    If you think the map is incorrect or incomplete, you can submit a challenge to the FCC to correct it.

    If the information about the internet services available at your home, small business or other location is incorrect, you can dispute it by clicking on the Availability Challenge link on the right side of the map and submitting the form.

    Availability Challenges can correct the information on the map about the services reported by ISPs as being available.

    Location Challenges can add a missing location, correct an address or other details and correct the geographic placement of your location.

    Challenging Mobile Broadband Coverage
    If you believe the information on mobile coverage submitted by your provider is incorrect, you can dispute that information by taking outdoor (or in-vehicle) speed tests on your mobile phone with the FCC’s Speed Test App.

    The FCC Speed Test App is available in the Google Play Store for Android devices, and in the Apple App Store for iOS devices. Search for "FCC Speed Test" to find and download the App.
