Is Reverse Phone Lookup Legal in Illinois?

Yes. Illinois has no comprehensive consumer data privacy law. The state does have the Biometric Information Privacy Act (BIPA), but that law covers fingerprint and facial recognition data only - it has no bearing on general phone lookup services or your right to opt out of them. Federal FCRA rules apply statewide: using lookup results to screen job candidates, evaluate rental applicants, or make credit and insurance decisions is prohibited regardless of Illinois's lack of a general privacy statute.
