Check providers at your San Marcos address

Town-wide coverage tells you who is around. Whether a provider can connect your home is decided street by street, so finish with an address check.

  1. Step 1

    Look up the exact address

    Type your street address on the FCC National Broadband Map. It lists each provider that reports service at that home in San Marcos, with technology and top advertised speeds.

  2. Step 2

    Confirm with the provider

    Put the same address into each provider’s availability checker. New fiber builds can be missing from FCC data, and some listed coverage turns out not to be installable.

  3. Step 3

    Compare the broadband labels

    Providers must publish a standard “broadband facts” label for every plan, showing the monthly price, fees and typical speeds. Compare those, not the headline offer.
