Where this comes fromFCC filings and how to check one address
Check service at your address
The figures on this page summarize what providers reported to the FCC for all homes in Atherton. They do not confirm that any provider serves a particular address, and providers' reports can overstate coverage. Two ways to check your own address:
- Search your address on the FCC National Broadband Map.
- Call (815) 934-8169 and we will look up the providers and plans available at your address. We are an independent service, not your provider.
Sources
Provider availability comes from the FCC National Broadband Map (provider filings as of December 30, 2025): a provider is "available" where its filing covers most homes and "available in some areas" where it covers part of them. Household counts come from the Census Bureau's American Community Survey (ACS 5-year 2020-2024), which are estimates with margins of error.
