How to Find an Inmate in Michigan
If someone you love was just arrested or sent to prison in Michigan, the first thing you need is also the hardest to get: a straight answer about where they are. Michigan does not have one single database that lists everyone in custody. The person you are looking for could be in a county jail, a state prison, a federal facility, or immigration detention, and each of those is searched a different way. Michigan does have one real advantage: its state offender search, known as OTIS, is one of the more thorough public systems in the country, and it covers more than just people currently locked up. This guide walks you through all of it.
Start here: figure out which system is holding them
Before you search anything, answer one question, because it tells you which tool to use.
How long ago were they taken into custody, and what happened? Someone arrested in the last few days is almost always in the county jail for the county where the arrest happened. They stay there through booking, first appearance, and often through their whole case if it is a local charge. People do not go to "state prison" when they are arrested. They go to state prison only after they have been sentenced and transferred into the custody of the Michigan Department of Corrections, which can take weeks after sentencing.
So the rule of thumb is simple. Recently arrested, case still pending, or a short sentence: look in the county jail. Sentenced to state prison time and transferred: look in the Michigan Department of Corrections. Federal charge: look in the federal system. Immigration hold: look in ICE custody. Most families searching for someone newly arrested waste time on the state prison site when their person is sitting in a county jail.
Searching the Michigan state system (MDOC and OTIS)
The Michigan Department of Corrections, or MDOC, holds everyone serving a state prison sentence, and Michigan makes this easy to search. Its public system is called OTIS, the Offender Tracking Information System, and it is one of the more complete public corrections searches in the country.
What makes OTIS useful is its breadth. It does not only show people currently in prison. It also includes people on parole, people on probation supervised by the state, and people who were discharged from the system within recent years. So if your person is in state prison, was recently released to parole, or finished a sentence not long ago, OTIS can usually still show their record and status. You look a person up by name or by their MDOC number. To search you generally need the person's first and last name.
What OTIS will not tell you is anything about a county case. If your person was arrested recently and has not been sentenced and transferred to MDOC, they will not be in OTIS yet. That is normal. It means they are still in the county system.
Searching county jails in Michigan (recently arrested)
Michigan has 83 counties, and each one runs its own jail and inmate roster through the county sheriff's office. There is no single statewide county jail search, so you find the roster for the specific county where the arrest happened.
If you know the county, search that county's jail roster directly, or find the facility on InmateAid and use the search link on its page. By far the largest is Wayne County, which contains Detroit and recently consolidated its jail operations into a single new county facility, so a Detroit-area arrest is most often found through the Wayne County Sheriff's roster. After Wayne, the largest county systems are Oakland, Macomb (the two other big metro Detroit counties), Kent (Grand Rapids), Genesee (Flint), and Washtenaw (Ann Arbor). Each posts a current booking list, and most update within hours of someone being booked.
To search a county roster you typically need the full name. A booking number, if you have it, finds the record immediately. If you are not certain which county made the arrest, the city where it happened tells you: look up which county that city sits in, then search that county's jail.
Federal inmates in Michigan (BOP)
If the charge was federal, the person is in the custody of the federal Bureau of Prisons, not the state, and you search the BOP's own national inmate locator rather than any Michigan tool. It covers everyone in federal custody from 1982 to the present and searches by name or by federal register number.
Michigan has a modest federal presence, including FCI Milan in the southeast near the Ohio border, which also holds people whose federal cases are pending. People sentenced to federal time may be held there or at facilities in other states, and they appear in the BOP locator regardless of where they are held. A person arrested on a federal charge may first sit in a county jail under a federal contract before being moved, so if the BOP locator does not show them yet, check the county jail where the arrest happened.
ICE detainees in Michigan
If the person is being held on an immigration matter, they are in ICE custody, a civil detention system separate from criminal jail and prison. ICE detainees are not criminals serving sentences; they are held while their immigration cases are decided. Michigan's immigration detention runs primarily through county jails under contract with ICE, particularly in the central and western parts of the state, and detainees may be moved between facilities and to other states.
You search for an immigration detainee using the federal ICE Online Detainee Locator, which works by the detainee's A-Number (a nine-digit immigration identification number) or by their full name, country of birth, and date of birth. If you have the A-Number, use it, because name searches in the immigration system are far less reliable when names are common or were recorded differently than expected.
When you cannot find them anywhere
If you have searched and your person is not turning up, work through these explanations before assuming the worst.
The booking is not complete yet. Newly arrested people can take hours to appear on a roster. Try again later the same day. They were released, transferred, or moved between systems. Someone can post bail, get transferred to another county, or be handed from county to federal or immigration custody, and during a handoff they may briefly appear nowhere. The name does not match the record. People are booked under legal names, middle names, maiden names, or misspellings. Try variations, and search with less information rather than more. They are a minor. Juveniles are not listed in public adult locators at all, regardless of facility.
When the online tools fail, calling works. Call the jail or facility you believe is holding them, give the full name and date of birth, and ask the booking desk to confirm custody status. That is often faster than any website.
Get notified automatically: VINELink
Rather than checking rosters over and over, you can register with VINE, the free victim and family notification service Michigan participates in. It lets you look up a person's custody status and sign up for automatic alerts about changes such as transfer or release. It is the simplest way to stop refreshing a website every day.
Once you have found them
Finding the person is the first step. Staying connected is the next, and it matters more than most families realize for how someone gets through their time.
The best place to start is mail. Letters and photos reach almost everyone in custody, they are the most reliable form of contact, and a person who hears from home regularly does easier time. Phone calls are the next layer, and the cost of calls dropped sharply under the federal rate caps that took effect in April 2026, so calling is more affordable now than it has been in years. You can also send money to most facilities so your person can cover phone time, commissary, and basic needs.
To set any of this up for the specific facility holding your loved one, find that facility on InmateAid and follow the instructions on its page, since the rules, the phone carrier, and the mailing address are different at every facility.

Frequently asked questions
How do I find an inmate in Michigan?
Decide which system holds them first. Recently arrested people are in the county jail where the arrest happened. People serving state prison time are in the Michigan Department of Corrections, searched through OTIS. Federal charges mean the Bureau of Prisons, and immigration holds mean ICE.
Is there one website for all Michigan inmates?
No. Michigan has no single combined database. County jails, the state system, the federal Bureau of Prisons, and ICE each maintain separate searches, and you have to use the one that matches the person's situation.
What is OTIS?
OTIS is the Offender Tracking Information System, Michigan's public state offender search. It is unusually thorough, covering people in prison, on parole, on probation, and discharged within recent years.
How do I search the Michigan Department of Corrections?
Use OTIS, the state offender search, with the person's name or MDOC number. It returns current prisoners as well as parolees, probationers, and recently discharged people.
Where is someone who was just arrested in Michigan?
In the county jail for the county where the arrest happened, not in state prison. People only enter the state system after sentencing and transfer, which can take weeks.
How do I find someone in a Detroit or Wayne County jail?
Search the Wayne County Sheriff's jail roster. Wayne County, which includes Detroit, recently consolidated its jail into a single new facility, and it is the largest jail system in Michigan.
Why can't I find my inmate in OTIS?
The most common reason is that they are not yet in state custody. If they were arrested recently and not sentenced, they are in a county jail. They could also be in federal or immigration custody. OTIS does show recently discharged people, so an older record may still appear.
How do I find a federal inmate held in Michigan?
Use the federal Bureau of Prisons inmate locator, which is national and searches by name or federal register number. It is separate from any Michigan state tool.
How do I find someone in ICE custody in Michigan?
Use the ICE Online Detainee Locator, searching by the detainee's A-Number or by full name, country of birth, and date of birth. Michigan immigration detention runs largely through county jails under contract.
Can I get alerts when an inmate's status changes?
Yes. Register with VINE, the free notification service, to get automatic alerts about transfers and releases instead of checking rosters manually.
What if no search finds the person?
Try again later in case booking is not complete, and try name variations. OTIS covers recent discharges, so check there for older records. Minors are never listed publicly. If the websites fail, call the facility directly. ===================================================== PRE-PUBLISH VERIFICATION (remove before publishing - dev/editor checklist) ===================================================== State-specific items to confirm before this goes live: 1. OTIS - this is the distinctive Michigan hook. Confirm the current OTIS (Offender Tracking Information System) URL and the MDOC-number label/format. Confirm OTIS still covers current prisoners, parolees, probationers, and recently discharged people, and verify the discharge lookback window if a specific number is to be stated. Insert the live link on "OTIS." 2. Wayne County jail - confirm the new consolidated Wayne County jail facility (the Detroit-area jail consolidation) and the current Sheriff's roster URL. Verify the "recently consolidated into a single new facility" framing is accurate and current. Link to InmateAid facility page(s). 3. County list - confirm 83 counties and the largest-county list (Wayne, Oakland, Macomb, Kent, Genesee, Washtenaw); link each to its InmateAid facility page. 4. BOP locator - confirm URL; link "Bureau of Prisons inmate locator." 5. Federal facilities in MI - confirm FCI Milan and any other federal facility in the state; link to InmateAid facility pages. 6. State prisons - consider naming main MDOC facilities (e.g. the Jackson-area facilities, Marquette Branch up north, the Huron Valley women's facility) and linking to InmateAid pages; left general pending the facility-page list. 7. ICE in MI - confirm current county-jail ICE contracts (historically Calhoun County/Battle Creek, Chippewa, Monroe) before naming any; body keeps it general. 8. VINE - confirm Michigan's current VINE URL and link "register with VINE." 9. Internal links - wire /prisons/michigan, the FCC 2026 calls guide (canonical path), and the Arrest Record Search affiliate with I239 honest-label language. State-specific elements that make this page unique (not a clone): - OTIS named and explained as an unusually thorough state search covering prisoners, parolees, probationers, and recent discharges - given its own section and two FAQs, including the genuinely useful point that an older/discharged record may still appear (changes the "cannot find" guidance). - Wayne County (Detroit) as the dominant jail with its recent consolidation into a single new facility - its own FAQ. - Modest federal footprint anchored by FCI Milan. - Free-call status: not a free-call state (caps apply, not free).
