Do Not Call protection in Illinois

Illinois formally adopted the FTC's National Do Not Call Registry as its own state list rather than running a separate one, so a single free registration at donotcall.gov covers you. State authorities can still enforce against telemarketers who ignore it, in addition to any federal penalty.

Whatever your state does, the federal National Do Not Call Registry applies, and the Telephone Consumer Protection Act gives you a private right of action against certain unlawful calls. Report unwanted calls at the FCC complaint centre and fraud at ReportFraud.ftc.gov. In Illinois, the Illinois Attorney General also takes consumer complaints about scam calls.
