Check your address
- 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, with technology and top advertised speeds.
- 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.
- 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.
