Find an Illinois Inmate: County Jail, IDOC Prison, Court and Release Lookup
An Illinois inmate search can fail even when the person really is in custody because county jails and Illinois state prisons use different systems. A person arrested today may be in a sheriff’s jail, while a sentenced person transferred to state custody is searched through the Illinois Department of Corrections.
This guide helps you choose the right database first, verify the correct person, understand the custody record, locate court information, troubleshoot a missing result, and handle visits, calls, money, mail, release and victim notifications without bouncing between dozens of unexplained links.
Usually the first search for a recent local arrest.
Use the statewide locator after commitment or transfer to state corrections.
Illinois eliminated monetary bail for new pretrial decisions in 2023.
Current Illinois information checked August 2026.
Which Illinois inmate database should you search?
Start with the sheriff or detention center in the county where the arrest occurred.
Use the IDOC Individual in Custody Search and identify the current correctional facility.
Use the county Circuit Clerk to research the criminal case rather than relying on a jail roster.
Use the Federal Bureau of Prisons locator instead of IDOC. Federal prisons in Illinois are outside IDOC jurisdiction.
How to use the Illinois Department of Corrections inmate search
IDOC calls its public locator the Individual in Custody Search. Use this path when the person has entered Illinois Department of Corrections custody rather than when someone is merely being held in a county jail awaiting a local court proceeding.
How to find someone in an Illinois county jail
Illinois county jails are local detention facilities. The Illinois Department of Corrections inspects county jails for compliance with state standards, but IDOC does not operate one universal public county-jail roster.

How to read an Illinois inmate or jail search result
| Field | What it tells you | What to do with it |
|---|---|---|
| IDOC number | Illinois Department of Corrections identifier for an individual in state custody. | Save it for mail, deposits, facility verification and communication questions. |
| Booking number | A county-jail identifier assigned to a particular booking. | Use the exact local number when setting up deposits, mail or services at that jail. |
| Custody facility | Where the person is presently assigned according to the database. | Check that facility’s current rules before visiting, mailing or sending property. |
| Admission / booking date | When the person entered the applicable custody system or booking. | Use it to distinguish a current detention from an older record. |
| Charge | An alleged offense, conviction or custody-related offense description depending on the system. | Check the Circuit Clerk for the actual court docket and disposition. |
| Case number | Court identifier associated with a criminal prosecution. | Use the case number for court-date and docket research. |
| Release / projected date | A date generated under the applicable sentence or release framework. | Do not treat a projected date as an unconditional pickup time; custody status and legal holds may change. |
| Housing location | The unit, division or facility assignment used by the jail or prison. | Use it for visitation routing when the local agency requires housing information. |
| Hold / detainer | Another legal authority may have an interest in custody after the current matter. | Ask which agency issued the hold and whether transfer is expected. |
No Illinois inmate found? Diagnose the missing record
Booking, fingerprinting, medical screening and database entry may still be underway. Search the local county again and call the facility.
A person awaiting trial in county custody usually will not be found simply by searching the state-prison locator.
Try surname only, maiden name, hyphenated spelling, omitted suffix or another legal-name variation.
A newly arrested person may initially remain with a municipal police agency before transfer to the county detention facility.
If the local roster disappears after sentencing, immediately try the IDOC locator.
A newly committed IDOC individual can move through a reception center before receiving a permanent facility assignment.
Federal facilities—including federal institutions located in Illinois—do not fall under IDOC jurisdiction.
Juvenile records and placements have different confidentiality rules. Do not expect an adult county or IDOC search to function as a juvenile locator.
The person’s criminal court case may continue even after the active jail entry disappears.
A warrant or transfer can place someone in a county different from where the incident happened or where the person lives.
Illinois arrest-to-custody journey: where the inmate record moves
Illinois pretrial release: why old “cash bond” advice can be wrong
Illinois changed its pretrial system when the Pretrial Fairness Act provisions took effect on September 18, 2023. For new cases under the current system, monetary bail is no longer the mechanism used to decide whether a person remains detained before trial.
Illinois law establishes a general pretrial-release framework with conditions a court may impose when appropriate.
Pretrial detention may be ordered in statutorily authorized circumstances after the required court process.
When a person remains jailed, the court docket—not an old cash-bail explainer—is the place to investigate the detention order and next hearing.
Find the Illinois criminal court case and next hearing
Jail custody and court records answer different questions. A jail search answers where someone is being held. The Circuit Clerk record tells you about the criminal prosecution, court assignments, filings, future settings and case disposition.
County jail to IDOC transfer: what families should expect
One of the most confusing search periods occurs after a person leaves the county jail but before family members understand the new state-prison location.
Do not assume release. A sentenced person may have transferred to IDOC.
New state commitments may spend time in reception/classification before permanent assignment.
Do not mail or plan a long-distance visit until the IDOC facility is confirmed.
Important Illinois reception examples
| Facility | Role | Useful information |
|---|---|---|
| Northern Reception & Classification Center | Major adult male intake and processing unit. | IDOC says there is no fixed processing time; movement depends on the individual. Facility phone: 815-727-3607. |
| Graham Reception & Classification Center | Processes adult male commitments from certain counties. | IDOC describes a typical stay of about three weeks to two months, although medical holds, court writs, bed availability or other issues can make it longer. |
| Menard Reception & Classification Center | Reception/classification unit at Menard. | Regular visits are generally not allowed while housed in Menard Reception & Classification, except qualifying legal visits. |
How Illinois IDOC in-person visitation works
Facility hours differ, but IDOC publishes a statewide process that visitors should complete before traveling.
Items IDOC does not allow in the visiting room
Illinois IDOC video visitation rules in one place
IDOC has moved video visitation at its correctional facilities, except Adult Transition Centers, to ICSolutions.
| Rule | Current IDOC requirement | Why it matters |
|---|---|---|
| Approved visitor | Non-government/non-legal visitors must be on the individual’s approved visiting list. | Creating an ICSolutions account alone does not guarantee approval. |
| Advance booking | Schedule at least 7 days in advance. | A last-minute request will not satisfy the published rule. |
| Maximum advance window | Visits may be scheduled up to 30 days ahead. | Plan within the active booking window. |
| Daily limit | Individual in custody may receive 1 video visit per day. | Another scheduled visit can make your preferred date unavailable. |
| Weekly limit | Up to 2 video visits per week. | The weekly allowance includes applicable restrictive-housing visits. |
| Visitor count | Up to 3 approved visitors for general-population or protective-custody video visits under the statewide rule. | Only scheduled participants may appear. |
| Count period | No video visits are scheduled from 2:30 p.m. to 4:30 p.m. | This period is reserved for institutional count procedures. |
| Recording | Video visits are monitored live and recorded. | Do not treat ordinary family video visitation as confidential attorney communication. |
How to send money to an Illinois IDOC individual in custody
Do not use county-jail deposit instructions for a person who has already transferred to IDOC. State corrections currently lists specific electronic and lockbox options.
| Method | Limit / processing detail | Information required |
|---|---|---|
| JPay | Electronic funds may be sent up to the IDOC-published electronic limit. | Correct IDOC number and incarcerated last name. |
| Western Union Send2Corrections | IDOC says transfers through JPay and Western Union are generally anticipated within 24–48 business hours. | IDOC number and last name. |
| MoneyGram | Maximum listed MoneyGram transaction is $3,000; receiving code 7364. IDOC lists an anticipated 72–96 business-hour posting period. | IDOC number and last name. |
| Money order | Maximum $999.99. Must be sent to the lockbox with the required deposit slip—not to the prison. | Individual’s name, IDOC number, sender name and sender address. |
P.O. Box 260250
Hollywood, FL 33026
Include the completed IDOC deposit slip and make the money order payable to JPay.
Illinois IDOC phone calls and electronic messaging
Phone calls
IDOC currently uses ICSolutions as its telephone provider. Individuals in custody cannot receive ordinary incoming calls; they place outgoing calls to people on their approved calling list.
The outside contact can create and fund an ICSolutions prepaid account for calls.
Family or friends may fund the person’s trust account and the individual can purchase telephone minutes through commissary.
Use this number for issues receiving IDOC telephone calls or setting up applicable prepaid service.
Why a legitimate prison call may not ring
- Spam filtering may send the call to voicemail.
- The number may need an active prepaid arrangement.
- The person may not have you on the approved calling list.
- The facility may have operational or disciplinary restrictions.
- The caller-ID number may differ by correctional facility.
Electronic messages
IDOC uses the ICSolutions CorrLinks electronic messaging system at correctional facilities other than ATCs. Messages are screened and monitored, and IDOC applies a delay to incoming and outgoing electronic messages as part of its review process.
Illinois IDOC mail: address format, scanning and prohibited items
The safest workflow is to search the person first, note the IDOC number and current facility, then use the individual-in-custody mailing address listed for that specific prison.
What happens to ordinary non-privileged mail?
IDOC’s current procedure says incoming non-privileged correspondence—including ordinary letters, greeting cards and photographs—is generally processed by either:
The envelope and enclosed items can be scanned in color and distributed digitally to the person or printed for physical delivery.
Mailroom staff may color-photocopy the envelope and contents and distribute the copies.
Practical correspondence tips
Items IDOC lists as unauthorized or problematic
No stapled or paper-clipped pages, glued-together pages or oversized paper.
Do not place cash, coins, personal checks or money orders inside ordinary correspondence.
Unused stationery, envelopes, postcards, greeting cards, postage stamps and stamped envelopes are not ordinary approved enclosures.
Glue, glitter, paint, crayon, ribbon, cloth, string and similar materials can interfere with processing.
Oversized photos and photographs with prohibited content can be rejected. IDOC lists photographs larger than 8 × 10 as unauthorized.
Medication, clothing, electronic devices, jewelry, glasses, craft materials and many other tangible items cannot simply be enclosed in correspondence.
Publications
IDOC allows qualifying new or used publications—including books, magazines, newsletters and newspapers—when sent directly by an eligible publisher or distributor and when the material complies with correctional standards.
Privileged mail
Privileged correspondence follows a different process. IDOC opens privileged mail in the incarcerated person’s presence to inspect for contraband, verify sender identity and ensure that only qualifying legal or official matter is enclosed.
County-jail services are not the same as IDOC services
A major mistake is finding a county detainee and then following Illinois state-prison instructions. The deposit vendor, phone provider, mail address, visit schedule and housing rules can all be different.
| Task | County jail | IDOC state prison |
|---|---|---|
| Custody search | County sheriff/corrections locator. | IDOC Individual in Custody Search. |
| Identifier | Local booking or detainee number. | IDOC number. |
| Mailing address | County-specific mail process. | Current IDOC facility’s individual-in-custody mail address. |
| Money vendor | Varies by county. | Current IDOC deposit options include JPay, MoneyGram and Western Union. |
| Phone provider | Varies locally. | ICSolutions. |
| Video visits | Varies by jail and vendor. | ICSolutions at IDOC facilities except ATCs. |
| Court information | County Circuit Clerk. | Original committing court remains relevant; custody locator is not the court docket. |
Cook County Jail: quick Illinois inmate-search example
Many statewide searches are actually Chicago/Cook County custody searches. Cook County Department of Corrections operates separately from IDOC.
Chicago, IL 60608
Current published hours: 7 days a week, 8 a.m.–8 p.m.
Search/housing, visitation, trust-account and other automated assistance.
Cook County money example
Cook County accepts multiple local trust-account methods, including Western Union, MoneyGram, JailATM and on-site kiosks. These are Cook County rules, not the IDOC statewide deposit instructions.
Cook County medical/mental-health concern
773-674-2273 / 773-674-CARE
The line is intended for family/friend concerns involving immediate medical or mental-health needs of Cook County individuals in custody.
Illinois victim notification and release alerts
A victim or concerned family member should not rely on manually refreshing a jail roster as the only release-notification plan.
IDOC victim notification
Illinois Prisoner Review Board victim-notification services can notify registered crime victims about specified IDOC events, including:
How to use the Illinois IDOC facility directory
After locating a state prisoner, the facility page is where you should verify the physical/business address, individual-in-custody mailing address, telephone number and institution-specific visitation details.
Many IDOC facilities publish one address for business mail and another address for individual-in-custody correspondence.
Statewide visitation rules do not mean every institution has identical visiting days and times.
IDOC recommends contacting the institution directly when the question involves local facility policy.
Examples of why you must check the facility
| Facility | Published example | Lesson |
|---|---|---|
| Northern Reception & Classification Center | Current facility page lists in-person visitation 8 a.m.–2:30 p.m. daily, subject to facility conditions. | Reception rules and status can differ from a permanent prison. |
| Menard Reception & Classification Center | Regular visitation is not available for reception individuals except qualifying legal visits. | Never infer one IDOC institution’s visiting rules from another. |
| Lawrence Correctional Center | The published schedule varies by population and day, including different periods for general population, administrative detention and protective custody. | Custody status can affect the available visiting window. |

Common Illinois inmate-search mistakes that waste time
Recent pretrial custody is commonly local. Start with the county.
The person may have transferred to IDOC or another jurisdiction.
Illinois’ current pretrial system does not use monetary bail for new pretrial release decisions.
First identify which correctional system actually holds the person.
Run the IDOC search again before mailing because facility assignments change.
An online reservation does not replace the requirement to be on the individual’s approved visitor list.
IDOC says staff cannot confirm a prospective visitor’s list status by phone. Ask the person in custody.
Use the county Circuit Clerk to determine the actual court result.

Illinois jail inmate search FAQs
How do I search for an inmate in Illinois?
Determine the custody type first. Search the county sheriff’s jail roster for a recent local arrest. Search the official IDOC Individual in Custody Search when the person has entered Illinois state-prison custody.
Is there one Illinois county jail inmate search for the entire state?
No. Illinois county jails are locally operated and do not appear in one universal state jail roster. Each participating county uses its own sheriff or corrections search system.
How do I use the Illinois IDOC inmate lookup?
Open the official IDOC Individual in Custody Search, locate the person using the identifying information available to you, verify the match, save the IDOC number and note the current correctional facility.
Why can’t I find someone in the Illinois IDOC search?
A recently arrested person may still be in county or municipal custody. Other explanations include name variations, release, transfer, federal custody, juvenile custody or a local case that never resulted in an IDOC prison commitment.
Does Illinois still use cash bail?
Illinois’ current pretrial system abolished monetary bail beginning September 18, 2023. Courts decide release conditions or detention under the statutory pretrial process. Older cases can still contain legacy monetary-bond information.
How do I visit someone in an Illinois state prison?
Confirm the current IDOC institution, make sure you are on the individual’s approved visitation list, schedule the visit through the current IDOC process, check the institution’s hours/restrictions and bring two forms of ID, including one state-issued photo ID.
How does Illinois IDOC video visitation work?
IDOC currently uses ICSolutions at its correctional facilities except ATCs. Visits must generally be booked at least seven days ahead and no more than 30 days ahead. The statewide limit is one video visit per day and up to two per week for the individual in custody.
How can I send money to an Illinois state prisoner?
IDOC currently lists JPay, MoneyGram and Western Union Send2Corrections for electronic deposits. Use the correct IDOC number and incarcerated last name. Money orders up to $999.99 go to the JPay lockbox with the required deposit slip rather than directly to the prison.
How do I send mail to an Illinois IDOC inmate?
Use the IDOC locator to confirm the current prison and IDOC number. Address mail to the individual-in-custody mailing address published for that facility. Most ordinary incoming correspondence is now scanned or color-photocopied before delivery.
How do I find the Illinois court case after locating an inmate?
Identify the county where the prosecution was filed and use that county’s Circuit Clerk record system. Copy the case number from the custody record whenever possible because the jail roster and court docket are separate records.
