What people report Illinois calls as
Reports over the last 6 months
Reports are self-submitted to the FTC and FCC and are not independently verified. Phone numbers are frequently reassigned and can be ported across the country, so an area code doesn't necessarily reflect where a caller is today. Read our privacy policy for more.

Illinois doesn't run its own Do Not Call registry — residents are covered by the National Do Not Call Registry. See our guide to what it actually stops and file a complaint directly with the FTC or FCC if you get an unwanted call.
