Find Someone Arrested or Held in Chicago

A Chicago jail inmate search can mean two different things. If the person has been transferred into the Cook County Jail system, use the Cook County Sheriff’s Individual in Custody Locator. If you are looking for an adult arrest made by the Chicago Police Department, use CPD’s separate Arrest Record Search.

For someone arrested only a few hours ago, check both systems rather than assuming a blank result means the person was released. A person can still be going through police processing, court processing or jail intake.

If the Chicago Jail Search Shows No Result

A blank result does not automatically mean there was no arrest or that the person has been released. Work through these possibilities in order.

Possible reasonWhat to do next
Arrest happened very recentlyAllow time for police processing, court movement and Cook County intake. Recheck the locator later.
Name is entered differentlyRetry the full legal name, alternate spelling, maiden name, hyphenated surname or suffix.

Federal case or custodyUse a federal inmate or detainee search instead of the county locator.

Free legal help for someone still at a police station

The Cook County Public Defender operates an Arrest Hotline at 844-817-4448, 24 hours a day, 365 days a year. The arrested person, a family member or a friend can call.

How Cook County Jail Visitation Works

Do not travel to the jail simply because the locator shows a housing division. Cook County requires a visitor process before an in-person visit.

  1. Find the person in the Individual in Custody Locator.
  2. Write down the Booking ID and current housing division.
  3. Complete the required visitor application.
  4. Wait for approval and follow the current scheduling instructions.
  5. Confirm the visit date, division and identification requirements before leaving home.

Adult visitors are subject to a background check and current CCDOC visitor-eligibility rules. Minors age 17 or younger do not complete their own application, but they must be accompanied by an approved parent or guardian. High-school-age minors may be required to show a current school or state photo ID.

Cook County also provides family video visitation through Microsoft Teams under its current procedures. The visitor needs an active Teams account connected to an email address.

Mail, Money and Phone Calls After You Find the Inmate

Sending mail

Cook County instructs senders to include the person’s name and Booking ID.

Individual in Custody Name
Booking #
2700 S. California Ave.
Chicago, IL 60608

Mail sprayed or saturated with perfume, cologne or another foreign substance can be treated as contraband. Packages containing prohibited material can be rejected, so check the current CCDOC mail rules before sending anything beyond ordinary correspondence.

Adding money to a trust account

You will need the person’s exact jail name and Booking Number as shown in the official locator.

Deposit methodCurrent Cook County detail
Western UnionCity Code: CCDOC or COOK COUNTY DEPT CORRECTION; State: Illinois.

Electronic deposits may take 1–2 business days to post. Mailed money orders and cashier’s checks may take up to 5 business days after receipt. Verify current instructions on the official trust-account page before sending funds.

Phone calls and messages

Cook County currently uses ViaPath/GTL services for individual-in-custody communications. Friends and family can create prepaid accounts to receive calls.

  • Local, intrastate and interstate calls are currently published at $0.05 per minute.
  • Calls to Mexico and Canada are currently published at $0.08 per minute.
  • Other international calls are currently published at $0.13 per minute.
  • Text messages sent to an individual in custody are currently listed at $0.06 per message.
  • Communications can be monitored and should not be used for confidential attorney-client discussions.

Because providers and rates can change, check the Sheriff’s current phone-account instructions before adding money.

Bond, Pretrial Release and Cook County Court Information

Illinois changed its pretrial system on September 18, 2023. New criminal cases no longer use cash bail as the standard method for obtaining pretrial release. Courts decide whether a person should be released, released with conditions or detained under Illinois’ current pretrial framework.

Older cases filed before September 18, 2023 can still involve a cash-bond requirement. That is why the Cook County Sheriff continues to publish bonding procedures.

If an older case still has a payable bond

  • Division 5 bonding location: 2700 S. California Ave., Chicago.
  • Current published jail bonding hours: 10 a.m.–6 p.m., 365 days a year.
  • Published methods include cash, certified check and credit card where applicable.
  • Money orders are not accepted for bond.
  • After an applicable bond is posted, the Sheriff says discharge can take approximately 2–3 hours, with longer processing possible for holds, paperwork or GPS monitoring.

Check the current Cook County bonding page before traveling or paying anything.

How to check charges, hearings and court dates

The jail locator is a custody system, not the official criminal court docket. After identifying the person, use the Clerk of the Circuit Court of Cook County case lookup for available court-case information.

  1. Open the Clerk’s case lookup.
  2. Search using the defendant or case information available to you.
  3. Confirm that the result belongs to the same person found in the jail or arrest record.
  4. Review available case status, hearings and docket events.
  5. Use the Clerk or court directly if an official or certified record is required.
Do not treat charges as convictions. An arrest, jail booking, criminal charge, mugshot or custody listing does not establish guilt. Court disposition records are the better source for determining what ultimately happened in a criminal case.

If the Person Left Cook County Jail

A person can disappear from the Cook County locator because of release, transfer, sentencing or movement into another correctional system.

Illinois state prison

If the person received a state sentence and was transferred from Cook County, use the Illinois Department of Corrections Individual in Custody Search. IDOC supports searches using a last name, IDOC number or birth date.

Federal custody

A federal arrest or sentence uses a different custody system. Our Federal jail inmate search and booking guide explains when to use the Federal Bureau of Prisons locator and why recently arrested federal defendants may not immediately appear there.

Simple rule:
  • Just arrested by Chicago Police → check CPD arrest information.
  • Booked into Cook County Jail → use the Cook County IIC Locator.
  • Need the criminal case → use the Cook County Clerk.
  • Transferred to Illinois prison → use IDOC.
  • Federal prosecution or prison → use the federal custody system.

Chicago Jail Inmate Search FAQs

1. What is the official Chicago jail inmate search?

For someone currently held in Cook County Jail, use the Cook County Sheriff’s Individual in Custody Locator at iic.ccsheriff.org. For an adult arrest made by Chicago Police, use CPD’s separate Arrest Record Search.

2. Is the Chicago Police arrest search the same as the Cook County Jail locator?

No. The Chicago Police search provides public records for qualifying adult CPD arrests. The Cook County Sheriff’s locator is used for people booked into the Cook County Department of Corrections. One is primarily an arrest-record system; the other is a jail-custody system.

3. How long does it take for a newly arrested person to appear in Cook County Jail search?

The Cook County Sheriff says locator information is typically published about 4–6 hours after the person has been booked and processed. Police, court and transportation processing can occur before jail booking, so the total time from arrest can be longer.

4. Can I search Cook County Jail by booking number?

Yes. The official locator accepts a Cook County Booking ID. Enter the Booking ID without the hyphen. You can also search using the person’s full first and last name.

5. Why can’t I find someone who was arrested in Chicago?

The arrest may be too recent, the person may still be in a police facility, the booking name may be different, the person may have been released, or another law-enforcement agency may have made the arrest. They may also have moved into state or federal custody.

6. Can I find Chicago arrest mugshots online?

The official Chicago Police Arrest Record Search can display a mugshot when one is available for a qualifying CPD adult arrest. Cook County’s custody locator may also provide a booking photograph for a processed jail record when available.

7. What is the Cook County Jail address and inmate information number?

The main Cook County Department of Corrections address is 2700 South California Avenue, Chicago, IL 60608. The automated individual-in-custody information line is 773-674-5245, and Corrections Customer Service is 773-674-1945.

8. How do I visit someone in Cook County Jail?

First locate the person and confirm the current housing division. Adult visitors must complete the Cook County visitor-application process and receive approval. Follow the current scheduling instructions before traveling to the jail.

9. Does Cook County still require cash bail?

Illinois ended cash bail for new pretrial cases beginning September 18, 2023. Courts now decide pretrial release or detention under the state’s current framework. Some older cases filed before that date can still have a cash-bond requirement.

10. How do I find a Chicago inmate’s charges and next court date?

Use the jail or arrest search first to identify the correct person, then use the Clerk of the Circuit Court of Cook County for available criminal case and hearing information. If the person has been transferred to Illinois state prison, use the IDOC search instead.

Fastest Way to Complete a Chicago Inmate Lookup

Start with the Cook County Sheriff’s locator if you believe the person is already in jail. Use the Chicago Police search when you need a CPD arrest or booking record. Save the person’s Booking ID, confirm the housing division, then use the court system separately for charges and hearing information.

If the arrest happened only hours ago and no record appears, do not assume the person has been released. Processing delays are normal, and someone may still be in police custody before a Cook County jail record becomes available.
