Lake County Contacts

This is a private reference site, not a government office. We cannot confirm custody, release anyone, post bond, or retrieve an official booking record. Contact the responsible agency directly.

Choose the Record Holder

Directing the question to the right custodian saves time because arrest, custody, and court records are maintained separately.

  • Use the home page for official booking-record, photo, roster, warrant, and records-request routes.
  • Use the Lake County Sheriff’s current inmate portal or Adult Corrections phone line for present county custody.
  • Request a municipal arrest file from the police department that made the arrest.
  • Ask the Lake County Circuit Clerk about a filed case, hearing, order, or disposition.
  • Use the Illinois Department of Corrections search for state prison or parole status.
  • Use the federal Bureau of Prisons or ICE locator for those distinct custody systems.

Adult Corrections FOIA

Written booking-record requests may be sent through the Adult Corrections FOIA route and county portal, mailed to the address below, faxed to 847-984-5817, or delivered by hand. The public research did not state office hours, so verify hours before visiting.

Lake County Sheriff’s Office, Adult Corrections Facility
Attn: FOIA
20 South County Street
Waukegan, IL 60085

Hand-delivery instructions identify 29 South Martin Luther King Jr. Avenue in Waukegan. Name the record and arrest or booking date range as precisely as possible.

Court and State Records

The Lake County Circuit Clerk’s public eCourt portal is the official route for public case information and available documents. Its Criminal and Traffic line is 847-377-3250. For someone serving an Illinois state sentence or on parole, consult the Illinois Department of Corrections offender search instead of treating the county jail roster as a state-prison index.
