Is There a Mackinac County Jail Roster Online?
No official online Mackinac County jail roster was found in county or sheriff sources during research. Several third-party sites claim to show a local roster, but they are not official and should not be relied on. The real way to confirm custody is a phone call.
To check whether someone is held in the county jail, call the Mackinac County Jail at (906) 643-7325 or the Sheriff's Office administrative line at (906) 643-1911. Staff can confirm current county custody. For a person already sentenced to state prison or on state supervision, a separate statewide tool applies instead.
The county roster question also has limits. County jail custody does not cover federal detainees, immigration holds, or people already transferred to the Michigan Department of Corrections. Each of those groups sits in a different system with its own lookup path.
Mackinac County is rural and spread across more than a thousand square miles, yet its jail, sheriff, and courthouse share one complex in St. Ignace. That makes routing simple, because the same phone call can point a caller toward the jail, the court that set bond, or the FOIA channel for records. It also means the person answering the jail line can explain whether an inmate is still local or has moved on to state custody.
How to Confirm a Mackinac County Inmate
Because there is no search box for the county jail, confirming custody means working the phone and, for state cases, the OTIS system. The steps below follow the order that works best.
- Call the Mackinac County Jail at (906) 643-7325 to ask whether a specific person is currently in county custody.
- If the jail cannot help, call the Sheriff's Office at (906) 643-1911 during administrative hours.
- For someone sentenced or under state supervision, search the Michigan Department of Corrections OTIS system online.
- For court dates and charges tied to the person, look up the case through the county criminal court records or court charge records pages.
The official Mackinac County Jail page confirms the jail capacity and its state certification.
That page is the official source for jail facts, and it points callers back to the sheriff for anything about a specific person in custody.
Mackinac County Jail Facility Details
The Mackinac County Jail sits in the same government complex as the courthouse and sheriff on South Marley Street. It has a rated capacity of 28 inmates and is certified by the Michigan Department of Corrections as meeting local jail standards. Its small size shapes how long people stay before a transfer.

The Michigan Department of Corrections certification means the jail meets state standards for a local correctional facility. That certification covers how the jail operates, not who is held on a given day, so it does not replace a phone call for current custody.
Note: With only 28 beds, some sentenced or transferred inmates leave county custody quickly and then appear in the state OTIS system instead.
County Jail vs State Prison Custody
People mix up the county jail and state prison, but they hold different groups. The county jail holds people awaiting court, serving short sentences, or waiting on a transfer. State prison and state supervision fall under the Michigan Department of Corrections. The comparison shows where to look.
| Feature | Mackinac County Jail | State (MDOC / OTIS) |
|---|---|---|
| Who is held | Pretrial, short sentences, holds | Prison, parole, probation under MDOC |
| How to check | Call the jail | Search OTIS online |
| Records | Local booking and custody | State offender profile |
| Coverage | Current county custody only | Statewide, last three years of jurisdiction |
The MDOC OTIS about page explains exactly who the state database covers.
Reading that page first saves time, because a person only in county custody will not appear in the state results.
How to Use MDOC OTIS for Mackinac County Cases
The Offender Tracking Information System, or OTIS, is the state tool for people under Michigan Department of Corrections jurisdiction. It works for Mackinac County residents who were sent to prison or placed on state parole or probation. It does not list current county jail inmates.
- Open the MDOC OTIS search page.
- Enter the offender last name and first name, or the MDOC offender number if you have it.
- Use the sex, race, or age filters to narrow common names.
- Open a matching result to view the state offender profile.
The search page accepts the fields listed below.
Those fields let a searcher work from a name alone or from a known offender number.
| Field Label | Type | Required | Notes |
|---|---|---|---|
| Last Name | Text | No | Search by offender last name. |
| First Name | Text | No | Search by offender first name. |
| Offender Number | Text | No | The MDOC offender number, if known. |
| Sex | Radio | No | Either, Male, or Female. |
| Race | Dropdown | No | Filter by listed race categories. |
| Age | Number | No | Age filter to narrow results. |
What an OTIS Offender Profile Shows
No official Mackinac jail profile was viewable, so no county booking fields were observed during research. The inventory below reflects the state OTIS offender profile, and it should be read as state prison, parole, or probation information rather than county jail booking data.
| Field | What It Shows |
|---|---|
| Offender Number | The person's MDOC identification number. |
| Status | Prison, parole, probation, or discharged within the covered period. |
| Physical Description | Sex, race, and age details on file. |
| Offense | The offense or offenses tied to the state case. |
| Supervision | The supervising office or facility, when listed. |
OTIS covers people under MDOC jurisdiction, generally within the last three years, and it does not include county jail inmates or FOIA-exempt information. Its results reach prisoners, parolees, and probationers under state supervision, along with interstate compact transfers, escapees, and absconders tied to Michigan. For a Mackinac County resident, that means a felony sentence to state prison shows in OTIS, while a night in the county jail before arraignment does not.
Booking and Custody in Mackinac County
After an arrest, a person is booked into the county jail, where intake and classification happen. Intake records identifying details and any immediate medical or safety needs, and classification decides where a person is housed within a small facility. A first court appearance follows, often in the 92nd District Court, where bond and the next steps are set. Because the jail is small, custody can shift soon after sentencing.
Someone who is sentenced to state time or picked up on a state hold may transfer out of the county jail and into the Michigan Department of Corrections system. That is when the OTIS search becomes the right tool rather than the county jail phone line.
Bond is a key moment in the booking timeline. At the first appearance, a district judge or magistrate can set a cash bond, a surety bond, or release on personal recognizance. A person who posts bond leaves custody while the case goes on, so the jail list changes from day to day. For the charges behind a booking, the county court charge records page explains how the prosecutor files and amends counts.
The state Michigan Corrections OTIS page describes current and recently discharged prisoners, parolees, and probationers.
Watching both the county jail and the state system covers the full path a person can take through custody.
Visitation, Mail, and Money at the Mackinac County Jail
Mackinac County does not publish a full visitation schedule, mail policy, or commissary guide on its official pages. Rules at a small jail can change fast because of staffing, classification, lockdowns, or holidays. The safest step is to call the jail before sending mail, scheduling a visit, or depositing money.
| Topic | Official rule located | What to do |
|---|---|---|
| In-person visitation | Not published | Call the jail before arrival. |
| Visitor ID | Not published | Ask what identification is required. |
| Mail format | Not published | Confirm the address format and banned items. |
| Money deposits | Not published | Ask how funds can be added. |
| Attorney visits | Not published | Attorneys should call the jail or court first. |
Note: Call the Mackinac County Jail at (906) 643-7325 for the current visit, mail, and deposit rules before you make the trip to St. Ignace.
Sheriff Mobile App and Public-Safety Contact
The Mackinac County Sheriff offers a free mobile app for tips, crime reporting, and public-safety news. It is a communication tool, not an emergency line, and no official app-only inmate lookup was confirmed in the store listing. For custody questions, the jail phone line remains the direct route.
The warrant records page covers the same app in the context of active-warrant questions, and an emergency always means calling 911.
Mackinac County Inmate Search Questions
Can I find a Mackinac County inmate online?
There is no official online roster for the county jail. To confirm current county custody, call the Mackinac County Jail at (906) 643-7325 or the Sheriff's Office at (906) 643-1911. A person who has moved into state prison, parole, or probation can be found through the Michigan Department of Corrections OTIS system instead.
Why does OTIS not show a person I know is in the county jail?
OTIS only covers people under state Department of Corrections jurisdiction. Someone held in the county jail before trial, or serving a short local sentence, is not in the state system unless they are also under state supervision. County custody is confirmed by phone, not through OTIS.
How long does someone stay in the Mackinac County Jail?
It varies by case, and the jail holds only 28 beds. People awaiting court, serving short sentences, or waiting on a transfer make up the population. A sentenced or transferred person can leave county custody quickly, which is why the roster shifts and why a phone call gives the most current answer.
How do I put money on an inmate account or schedule a visit?
The county does not publish a commissary vendor, deposit method, or visitation schedule online. Call the jail at (906) 643-7325 first and ask for the current rule before you send money, mail, or plan a visit, since a small jail can change its procedures on short notice.
Requesting Mackinac County Jail Records
If a reader needs jail policies or records for a research or legal purpose and the jail cannot share them by phone, a written FOIA request is the next step. The County Clerk serves as the FOIA Coordinator, and requests can be sent by letter, fax, email, or in person.
The county must respond within five business days, with a possible ten business day extension. Some law-enforcement and jail records may be redacted or withheld for security or because release would interfere with an active investigation.
Written requests can describe the exact records sought, such as a jail policy, a booking log format, or a custody record for a named person and date. Standard copy fees are capped at ten cents per sheet, and the county may charge for staff time in fifteen-minute increments. For records tied to a court case rather than jail operations, the clerk of the court that holds the case is the better first stop, since court files follow court rules rather than the FOIA process.
