Cook County Sheriff and Booking Records

The Cook County Sheriff's Office runs the jail and holds all booking release records for the county. Every person brought into Cook County Jail gets a booking ID number. Staff log the charge, bond amount, and court assignment at that time. The jail sits on a 96-acre campus that spans eight city blocks at 2700 South California Avenue in Chicago. On any given day, roughly 5,750 people are held there. That makes it one of the busiest booking and release operations in the whole country.

Cook County Booking Release FOIA Requests

For records that go beyond what the online tool shows, you can file a Freedom of Information Act request. Illinois law under 5 ILCS 140 gives the public the right to ask for government records, and that includes booking release files held by the Cook County Sheriff. The office must respond within five business days of getting your request. Responses may come faster for simple lookups, but large or complex requests can take longer if the office needs more time to gather files.

The Cook County FOIA page for the Sheriff's Office provides the submission form and guidelines for records requests.

This page walks you through the steps to submit your request and tells you what to include so the office can find your records faster.

FOIA fees in Cook County are quite low. The first 50 pages of any response are free. After that, the office can charge up to $0.15 per page. Certified copies cost up to $1.00 per record. You should include the person's full name and any booking or ID numbers you have. The more details you give, the faster the staff can pull the right Cook County booking release records. Under 5 ILCS 140/2.15, arrest reports must be made available within 72 hours of the arrest taking place. That provision can be useful if you need very recent booking data from Cook County.

Illinois Laws on Booking Release Access

Several state laws shape how booking releases work in Cook County and across Illinois. The Illinois Freedom of Information Act (5 ILCS 140) is the main law that gives the public the right to see government records. It covers arrest logs, booking data, and release records held by any public body, including the Cook County Sheriff. The law sets deadlines for responses and caps what agencies can charge for copies. It also lists narrow exemptions for things like ongoing investigations or personal safety concerns.

The Criminal Identification Act (20 ILCS 2630) adds another layer of rules. This law controls who can see criminal history records and under what conditions. Arrest records and booking data fall under its scope. Certain records may be sealed or expunged under this act if a court orders it. When that happens, the Cook County booking release file for that person gets removed from public view. Still, most booking and release records in Cook County remain open to anyone who asks for them, as long as no court order says otherwise.

Note: Sealed or expunged records will not appear in the online inmate locator or through standard FOIA requests in Cook County.
