The Marquette County, Michigan Jail Inmate Roster is a public tool that allows anyone to check who is currently in custody at the county facility. MarquetteCourt.us provides access to publicly available information about current and recent inmates. Additionally, data can be obtained through the official website of the Marquette County Sheriff's Office, in person at the jail reception, or by phone. The registry search allows you to find out a person's custody status, charges, and booking date. The registry is maintained by the Marquette County Sheriff's Office and is updated regularly to reflect the current inmate population.
Search Current Inmates in Marquette Jail
There are several ways to find information about individuals currently in the Marquette County Jail.
Online Search
- Go to MarquetteCourt.us to search among publicly available court records and inmate information.

- Review the results — each record typically includes the name, booking date, charges, and custody status.
To search for court cases related to criminal charges in the Marquette Circuit Court, use the MiCOURT Case Search system. Note: this database is informational and does not replace the official court record.
By Phone
Call the jail directly on the non-emergency line. The operator can confirm if a specific person is in custody if you provide the full name and date of birth.
In Person
Visit the Marquette County Jail reception during business hours. The staff will provide basic information about the detained individuals.
Marquette County Sheriff's Office / Jail
Information about juvenile offenders is not displayed in the public registry — this restriction is established by Michigan state law. Marquette Juvenile Division cases are also closed to public access.
Find Marquette Jail Booking Records Online
A booking record is created at the moment a person is officially admitted to the jail. It is the first document that records the fact of detention.
What is recorded during booking:
- Unique booking number
- Date and time of admission
- Charges presented
- Arresting agency (Marquette City Police, Michigan State Police or another agency)
- Basic identification data of the detainee
Most of this information automatically enters the public inmate registry. If you need more detailed information — such as a copy of the arrest report or a full list of charges — submit a public records request through the Sheriff's Office. In Michigan, such requests are governed by the Freedom of Information Act (FOIA); the form can be submitted through the Michigan State Police FOIA portal or directly to the county sheriff.
To check a person's criminal history at the state level, there is the ICHAT system, maintained by the Michigan State Police Criminal Justice Information Center. This database allows searching for public records of criminal history.
If the person has already been transferred to a Michigan Department of Corrections facility (such as Marquette Branch Prison), information should be sought through the OTIS — Offender Tracking Information System. This system does not contain data on individuals in county jails — only those convicted in state institutions.
Search the Marquette Jail Roster by Last Name or Booking Number
The registry supports two main search methods.
Search by Last Name
Enter the last name in the search field. Adding the first name will narrow the results if the last name is common. Some practical tips:
- Check the spelling — one letter error can mean no results.
- Try spelling variations if the name has non-standard transliteration.
- On some platforms, you can enter only the first few letters of the last name for a partial search.
Search by Booking Number
The booking number is the most accurate identifier. If you have it, enter it for instant access to a specific record. This method is useful when you have already obtained the number from a lawyer or a previous search.
What to Do If the Search Yields No Results
- Ensure the name is entered correctly.
- The person may have already been released — the registry only shows those currently in custody.
- The booking may not yet be completed: there is a time gap between the actual arrest and the appearance of the record in the system.
- Call the jail at (906) 225-8435 for clarification.
- If the person has been sentenced to a state institution, use the OTIS search.
Jail Roster Updates and Search Limitations in Marquette
The Marquette County Jail inmate roster is not an archive of all past detentions. It only displays individuals who are in custody at the time of viewing.
Main limitations to be aware of:
- Delay between arrest and record appearance. The booking process includes identification, photographing, and data entry. This usually takes from a few minutes to several hours.
- Disappearance of records after release. Once a person is released on bail, by court decision, or after serving their term, their record is removed from the active registry.
- Data entry errors. Sometimes names or charges are entered incorrectly, complicating the search.
- Absence of minors. Records of individuals under 18 are not published.
The frequency of registry updates depends on the internal procedures of the Sheriff's Office. In practice, data is updated throughout the business day, but the exact interval may vary.
To access old booking records or archival data, submit a written FOIA request to the Marquette County Sheriff's Office. The Marquette County Clerk's Office can also assist with public records related to court cases and administrative documents.
