Parole and Probation in Illinois

If someone you love is on supervision in Illinois, or if you have just gotten out and are trying to understand what is expected of you, this guide is written for both of you. Illinois uses terminology that confuses people constantly: what most people call parole, Illinois calls Mandatory Supervised Release, or MSR. Traditional discretionary parole, where a board votes on whether to release someone, was abolished in Illinois in 1978. Almost everyone released from prison today goes out on MSR, not parole, and the timing is set by formula, not a board vote. Understanding this distinction is the key to everything else.

The terminology: MSR vs. parole vs. probation

Three forms of supervision in Illinois, and the names matter.

Mandatory Supervised Release is the post-prison supervision period that follows a determinate (fixed) prison sentence. Illinois abolished discretionary parole in 1978, so for people sentenced after that date, release to MSR is automatic. The Illinois Department of Corrections calculates the release date based on the sentence and earned good conduct credit. No board votes on whether to release someone to MSR. The Illinois Prisoner Review Board sets the MSR conditions and handles violations, but it does not decide the release date.

Traditional parole still exists in Illinois in two narrow situations. The first is for C-numbers, people convicted before the 1978 reforms who received indeterminate sentences like ten to thirty years. Fewer than 40 of these individuals remain in the system. They appear before the PRB every one to five years for a parole vote. The second is youthful parole, a newer mechanism for people who were under age 21 at the time of their offense. Starting January 1, 2026, people who qualify can request a parole review up to three years before they become eligible.

Probation is a sentence served in the community instead of prison, imposed by a court at sentencing. Illinois courts impose probation; IDOC parole agents supervise probationers in the field under the same structure as MSR.

How to find someone in Illinois

The Illinois Department of Corrections runs a public Individual in Custody Search on its website, searchable by name or IDOC number. The IDOC number is the identification number assigned to each person in state custody. The search shows current facility, sentence information, and projected release date.

For people on MSR or parole in the community, they are no longer shown as currently incarcerated but remain under IDOC supervision. Contact IDOC's parole services or the district parole office for the area where your person lives to confirm supervision status and find the assigned agent.

For people on probation, their supervision is also through IDOC's parole agent structure. Contact the relevant district office or the sentencing court.

Cook County, which covers Chicago, runs its own county jail inmate search through the Cook County Sheriff's Office for people in county custody rather than IDOC.

How MSR works in Illinois

When someone is sentenced to prison in Illinois for a determinate offense (virtually everyone sentenced after 1978), MSR is built into the sentence. The length of the MSR term is set by statute based on the offense class. For most Class 1 and Class 2 felonies it is two years; for Class X felonies it is three years; for murder it is three years; for sex offenses it can be significantly longer, up to natural life in some cases.

IDOC calculates the MSR release date. The Illinois Prisoner Review Board, which is independent from IDOC, sets the conditions of MSR before the person is released. Standard conditions include regular reporting to a parole agent, remaining in Illinois without permission to travel, no new criminal conduct, drug and alcohol testing, maintaining approved housing, and compliance with any special conditions the PRB imposes based on the individual case.

Once on MSR, the person is supervised by an IDOC parole agent. Until final discharge, they remain under the legal custody of IDOC and can be returned to custody for violations.

If a violation is alleged, the PRB holds a revocation hearing. For a technical violation, the PRB can impose a range of sanctions. A new criminal charge triggers both a new case and a revocation proceeding.

MSR can be terminated early. The PRB conducts Early Discharge Reviews for people on MSR who are seeking early termination.

Youthful parole in Illinois

Illinois enacted a youthful parole law that applies to people who were under age 21 at the time of their offense. For most crimes, parole consideration is available after ten years of incarceration, with additional reviews at fifteen and twenty years if initially denied. As of January 1, 2026, people who qualify can request a parole review up to three years before they become eligible, rather than waiting until the exact eligibility date.

This is a meaningful change for families of people sentenced as young adults in Illinois. If your person was under 21 at the time of their offense, consult an attorney to determine whether they qualify and when to file.

Cash bail abolished: what it means

Illinois made national history on September 18, 2023, becoming the first state in the country to completely eliminate cash bail under the Pretrial Fairness Act, which is part of the broader SAFE-T Act. Cash bail no longer plays a role in whether someone is held before trial. Judges now make pretrial detention decisions based on public safety assessments, not financial ability.

This matters for families navigating the system because it means that someone arrested in Illinois is not sitting in jail simply because they cannot afford bail. The question at a detention hearing is whether the person poses a public safety risk or a flight risk, not how much money they can come up with. Cook County's jail population dropped measurably after the law took effect.

How probation works in Illinois

Probation in Illinois is imposed by the circuit court at sentencing. Courts determine whether probation is appropriate based on the offense and the individual's history. Probationers are supervised by IDOC parole agents in the field, organized through IDOC's district structure.

Conditions are set by the court and spelled out in the probation order. Standard conditions include regular reporting, remaining in Illinois, no new criminal conduct, drug and alcohol testing, and payment of fines, fees, and restitution. Special conditions are added based on the case.

Probation violations are brought back to the sentencing court. The judge can modify conditions, continue probation, or revoke and impose a prison sentence.

Reporting and your supervision officer

This section is for the person on supervision. Whether you are on MSR, parole, or probation, your IDOC parole agent is the central person in your supervision. Know their name, their office, and how to reach them.

Know your conditions. Read the PRB release conditions or probation order and keep a copy. Know your reporting schedule. Ask before you miss anything.

Contact before you act. Travel, address changes, job changes, anything that touches your conditions requires approval first. For MSR and parole, housing must be approved by IDOC. You cannot simply move and inform them later.

For families: contact the IDOC district parole office for the area where your person lives to find the assigned agent. IDOC has district offices throughout the state; Cook County and the Chicago area have multiple offices given the population concentration.

Violations: what families should know

For MSR violations, the Prisoner Review Board holds the revocation hearing. The PRB is an independent body conducting hearings via video. A violation can result in return to IDOC custody for some or all of the remaining MSR term.

For probation violations, the sentencing court holds the revocation hearing. The burden of proof is lower than at a criminal trial. The judge has broad discretion.

In both cases: get an attorney involved immediately. Document mitigating circumstances. For PRB hearings, the board also awards Certificates of Relief from Disabilities and Certificates of Good Conduct, which attorneys can help pursue alongside the revocation defense.

Early termination and getting off supervision

For MSR, the PRB conducts Early Discharge Reviews. A person on MSR can request early termination if they have complied with conditions and circumstances support discharge.

For probation, a person can petition the sentencing court for early termination.

Illinois also has an expungement and sealing process for certain offenses. Getting off supervision is not expungement; they are separate proceedings. A criminal defense attorney is the right resource.
