Michigan inmate searches have a feature that catches people off guard: the MDOC Offender Tracking Information System (OTIS) purges records three years after a person's discharge from MDOC supervision. If someone completed their Michigan state prison sentence more than three years ago, their record will not appear in OTIS even though they were incarcerated. This is a statutory requirement — the Michigan Legislature mandates the purge. For recent sentences OTIS is reliable; for older history, the Michigan State Police ICHAT (Internet Criminal History Access Tool) is the supplemental source.
Beyond the state prison system, Michigan has 83 county jails — each operated by the county sheriff — with no statewide county jail aggregation. Wayne County (Detroit), Oakland County (Pontiac), and Kent County (Grand Rapids) are the highest-volume systems. Someone held pre-trial in Wayne County does not appear in OTIS. For broader Michigan public records context, see our Michigan people search guide and the three-tier inmate search overview.
Key takeaways
- MDOC OTIS at michigan.gov/corrections covers state prison inmates and people on parole or probation — but purges records three years after discharge, so older histories disappear.
- Michigan has 83 counties each with a separate jail — Wayne, Oakland, Kent, Macomb, and Washtenaw are the highest-volume systems with online portals.
- The Michigan State Police ICHAT provides name-based criminal history beyond the OTIS three-year window — it is the supplemental source for older Michigan convictions.
- After a felony conviction, the person typically remains in county jail two to four weeks before MDOC processes intake — they will not appear in OTIS during that window.
Fastest path for a Michigan jail search
For Detroit-area searches, Wayne County Jail inmate search is the first check for current in-custody status. For Oakland County subjects, the Oakland County Sheriff provides an online inmate locator. For state prison history, MDOC OTIS at michigan.gov/corrections is free. When the county is uncertain, a background report from a service like Instant Checkmate surfaces address history and narrows which county to check. For records older than three years that have disappeared from OTIS, Michigan State Police ICHAT is the supplemental free tool.
Michigan state prison: MDOC OTIS
The Michigan Department of Corrections operates the state prison system. The Offender Tracking Information System (OTIS) is available at michigan.gov/corrections and searches by name or MDOC number. It is free after accepting terms of use, and returns current facility, sentence information, conviction details, and parole or probation status for people currently under MDOC jurisdiction.
The three-year purge rule is the critical limitation. Michigan law requires MDOC to remove offender records from OTIS three years after the discharge date. This means someone who completed a state sentence in 2022 or earlier may no longer appear in OTIS as of 2026. The record is not expunged from underlying court systems — it just disappears from the public-facing OTIS portal. For historical Michigan criminal history beyond the three-year window, the Michigan State Police ICHAT at apps.michigan.gov/ichat is the next step, though ICHAT has its own access requirements.
OTIS does not cover county jails or pre-trial holds. The standard two-to-four-week transfer gap applies after sentencing.
County jail search in Michigan
Michigan has 83 counties. Each operates its own jail under the county sheriff. The highest-volume systems are below.
Wayne County (Detroit)
Wayne County contains Detroit plus 42 additional municipalities — one of the most municipally fragmented large counties in the country. The Wayne County Jail in Detroit is searchable through the Wayne County Sheriff's Office. Wayne County generates the highest jail booking volume in Michigan by a significant margin. Detroit arrests, Dearborn arrests, Livonia arrests, and arrests throughout the rest of Wayne County all route to the same county jail system despite being handled by dozens of separate municipal police departments. A Wayne County search covers all of them.
Oakland County (Pontiac)
The Oakland County Sheriff's Office provides an online inmate locator for current in-custody individuals at the Oakland County Jail in Pontiac. Oakland County is the wealthiest and one of the most populous counties in Michigan. It contains the northern Detroit suburbs — Troy, Southfield, Royal Oak, Birmingham, and dozens of others. Oakland County generates substantial civil and criminal filing volume relative to its population. Pontiac is the county seat but represents a small fraction of Oakland County's total population.
Kent County (Grand Rapids)
The Kent County Sheriff's Office provides an inmate search for the Kent County Correctional Facility in Grand Rapids. Grand Rapids is Michigan's second-largest city and the economic center of western Michigan. Kent County has grown rapidly over the past decade — address histories for Grand Rapids-area subjects may include prior addresses in metro Detroit or other states given the significant in-migration.
Macomb County (Sterling Heights/Warren)
The Macomb County Sheriff's Office provides an inmate search for the Macomb County Jail. Macomb County is the northeastern Detroit suburb — it contains Sterling Heights, Warren, Clinton Township, and Roseville. Many searches that turn up empty in Wayne County should extend to Macomb, since the Detroit metro population moves frequently between these adjacent counties.
Washtenaw County (Ann Arbor)
The Washtenaw County Sheriff's Office provides an inmate search for the Washtenaw County Jail. Ann Arbor is home to the University of Michigan, which creates above-average address churn for younger adults — student addresses in Ann Arbor are often stale within a year of graduation. Ypsilanti is also in Washtenaw County, generating a distinctly different demographic pattern from Ann Arbor proper.
Federal facilities in Michigan
Michigan has two federal correctional facilities: FCI Milan (medium security) in Milan and FCC Milan (which shares the campus). Federal charges in Michigan commonly involve drug trafficking, financial crimes, and public corruption — the Eastern District of Michigan (Detroit) and Western District (Grand Rapids) each handle substantial federal caseloads.
The BOP Inmate Locator at bop.gov is the free source for federal inmates. Pre-trial federal defendants in the Eastern District are often held at the Wayne County Jail under US Marshals contract and may not appear in BOP until formal transfer.
VINE: tracking custody status changes in Michigan
Michigan participates in VINE (Victim Information and Notification Everyday) at vinelink.com. VINE covers MDOC facilities and most county jails in Michigan. Registration provides automated phone or text notifications on custody status changes. For the OTIS three-year purge situation, VINE is not affected — VINE tracks current custody status independently of the OTIS public portal, so a person who has been purged from OTIS can still be tracked through VINE if they are currently in custody.
Industry insight
The OTIS three-year purge is the Michigan detail that surprises people most. Someone who was released in early 2023 will not appear in OTIS by 2026 — not because the record was expunged, but because Michigan law requires removal after three years. I have seen searches that returned nothing in OTIS for someone with a documented Michigan felony history, simply because three years had elapsed. If OTIS comes back empty and you have reason to believe there is a Michigan state conviction, ICHAT at apps.michigan.gov/ichat is the next check.
The Wayne County municipal fragmentation is the other practical complication. Wayne County has 43 municipalities each with their own police department, but they all route arrests to the same county jail. A Dearborn arrest, a Livonia arrest, and a Detroit arrest all end up in Wayne County Jail — one portal covers all of them.
Why Michigan jail searches come back empty
- OTIS record was purged after three years. Michigan law removes MDOC records from OTIS three years after discharge. The conviction still exists in court records — it simply no longer shows in the public portal. Use Michigan State Police ICHAT for older history.
- Checked OTIS for someone in county jail. OTIS covers state prisons only. Anyone held pre-trial or serving a short sentence is in a county jail, not OTIS.
- Transfer window not complete. After a Michigan felony conviction, the person remains in county jail while MDOC processes intake — two to four weeks during which OTIS returns nothing.
- Federal charge in the Eastern or Western District. Michigan federal cases go through BOP at bop.gov, not MDOC OTIS. Check BOP if the charge suggests federal jurisdiction.

Recommended services for Michigan jail searches
For Michigan inmate searches, these are the two services I recommend reviewing first. The OTIS three-year purge and the 83-county fragmentation both make a background report particularly useful when the county or time period is uncertain.
| Service | Why it helps for Michigan searches | Best fit |
|---|---|---|
| Instant Checkmate | Aggregates address history and arrest data — surfaces which county a person is associated with, and may surface conviction history that has been purged from OTIS after three years. | When county is uncertain, or when OTIS comes back empty despite known Michigan history |
| TruthFinder | Address history aggregation useful for subjects with movement across the Detroit metro (Wayne, Oakland, Macomb) or between Michigan and other states. | Identity confirmation and county routing for southeastern Michigan searches |
These services are not consumer reporting agencies and cannot be used for employment, tenant screening, insurance, credit, or other FCRA-regulated purposes.
Frequently asked questions
Why does OTIS show no record for someone with a Michigan felony conviction?
Michigan law requires MDOC to remove offender records from OTIS three years after discharge from supervision. If someone completed their state sentence more than three years ago, their record no longer appears in OTIS even though the underlying conviction exists in court records. The Michigan State Police ICHAT at apps.michigan.gov/ichat is the supplemental tool for older Michigan criminal history.
Can I find someone in a Michigan jail for free?
Yes. MDOC OTIS at michigan.gov/corrections is free for state prison searches. Wayne, Oakland, Kent, Macomb, and Washtenaw county sheriff portals are free online. VINE at vinelink.com provides free custody notifications for MDOC and most county jails. Smaller county portals vary — most larger counties have free online searches.
Can I use these searches for jobs, housing, or insurance decisions?
No. The services discussed on this page are not consumer reporting agencies and the information here is not a consumer report. They should not be used for employment, tenant screening, insurance underwriting, credit, or any other purpose regulated by the Fair Credit Reporting Act.
