Guide
Official Illinois Sex Offender Registry
Operated by Illinois State Police
Illinois maintains a public, searchable registry where you can look up registered sex offenders by name, address, ZIP code, county, or city. Information is provided by the responsible state agency and is the most authoritative source available.
Guide
What You Can Search
The Illinois registry typically lets the public search by:
- Offender name: First, last, or partial name match.
- Address or ZIP code: View registered offenders within a specified radius of an address.
- City or county: Browse the list of registered offenders in a specific area.
- Map view: Many states offer interactive maps showing offender locations.
- Email or text alerts: Subscribe to notifications when an offender registers near you.
Display rules vary by tier and jurisdiction. Some offenders may not appear publicly under state law. Always verify current status directly with the official registry or local law enforcement.
Guide
Using This Information Responsibly
Sex offender registry information is provided to help the public protect themselves and their families. It must not be used to harass, threaten, intimidate, or discriminate against any individual. Misuse may be a criminal offense under state and federal law.
If you have specific safety concerns or believe a registered offender is in violation, contact your local law enforcement agency or the Illinois State Police directly.
