About Illinois Criminal History

Illinois criminal records are divided among statewide and local systems. The Illinois State Police Bureau of Identification maintains the central repository, the Illinois Department of Corrections tracks people in state custody, and the Illinois State Police Sex Offender Registry publishes qualifying registration data. Circuit clerks and other local agencies hold the source records created in Illinois counties. Illinois Criminal History organizes routes to those systems so readers can start with the office that is most likely to hold the record they need.

Why This Site Exists

Public access in Illinois depends on the record and the agency that created it. The Illinois State Police, Division of Justice Services, Bureau of Identification collects reportable criminal-history information and provides official state products. The Illinois Department of Corrections maintains custody records. The Illinois State Police Sex Offender Registry is a separate statewide source. Trial-court files, bookings, jail records, and many police records remain local. This private reference site brings those routes into one organized statewide starting point. Readers looking for the source record can then use the Illinois county directory to reach the relevant local system.

What We Cannot Do

Illinois Criminal History is a privately operated reference resource. It has no affiliation with an Illinois court, police department, sheriff's office, or state agency. Those limits affect the help available here:

  • We cannot issue a certified court document, rap sheet, or other official record
  • We cannot conduct an official criminal-history check for a visitor
  • We cannot file an expungement, sealing request, records request, or court form
  • We cannot correct information held by the Illinois State Police or a local agency
  • We cannot provide legal advice about a charge, case, or person's rights

An official copy must come from the Illinois agency or court that created or maintains the record.

Search Partners

Some pages contain search boxes supplied by third-party providers. Those providers operate their own services, choose their prices, and control their results. A paid signup reached through one of those tools may generate a referral fee that supports this free reference resource. Illinois Criminal History does not set a partner's fees or decide what appears in a partner's response.
