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 Illinois. They do not confirm that any provider serves a particular address, and providers' reports can overstate coverage. Two ways to check your own address:

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.
