The Gallatin County jail roster is a public resource that lists individuals currently held at the Gallatin County Detention Center in Bozeman, Montana. GallatinCourt.us can help you find publicly available information about current and recent inmates, including booking details and charges. You can also access jail roster information through the Gallatin County Sheriff's Office website, by calling the detention center directly, or by visiting the jail lobby in person. A jail roster search lets members of the public confirm whether someone is in custody, view the charges against them, and find basic booking information. The Gallatin County Sheriff's Office maintains the roster, which is updated regularly and hosted on the county's official website.

Find Gallatin County Jail Booking Records Online
A booking record is created each time an individual is processed into the Gallatin County Detention Center. This record documents the intake and becomes part of the jail's administrative file.
Information generated at booking typically includes:
- Booking number
- Date and time of booking
- Charges at the time of arrest
- Arresting agency (Gallatin County Sheriff's Office, Bozeman Police Department, Montana Highway Patrol, etc.)
- Personal identifiers such as name, date of birth, and physical description
- Bond or bail amount, if set
Current booking records can usually be found on the jail roster through the Sheriff's Office website. For court-side records tied to a booking, search the Montana District Court Public Access Portal.
If someone has been transferred to state custody after sentencing, the Montana Department of Corrections Offender Search tool lets you look up convicted felons statewide. For formal criminal history checks beyond what the roster provides, the Montana Department of Justice background check process is available.
Search the Gallatin County Jail Roster by Last Name or Booking Number
The Gallatin County jail roster supports two primary ways to find an inmate:
Search by Last Name
- Enter the individual's last name. Adding a first name helps narrow results, especially for common surnames.
- Use correct spelling. If you are unsure of the exact spelling, try variations or a partial name if the system supports it.
- If the roster displays as a full list without a search field, use your browser's find function to jump to the name.
Search by Booking Number
- If you have a booking number — from a bail receipt, court document, or prior inquiry — enter it directly for an exact match.
- This is the fastest way to pull up a specific record when multiple people share the same name.
What to Do If the Search Returns No Results
- Double-check spelling and try alternate name formats (e.g., full middle name vs. middle initial).
- The person may have already been released, transferred, or not yet fully processed into the system.
- Call the detention center at (406) 582-2100 to verify custody status directly.
- If the individual was transferred to state prison, try the Montana Department of Corrections Offender Search.
Jail Roster Updates and Search Limitations in Gallatin County
The Gallatin County jail roster is updated regularly, but it is not instantaneous. There are practical limitations to keep in mind when relying on it.
Update Frequency
The roster is generally updated multiple times per day. However, there can be a delay between when someone is physically booked into the detention center and when their name appears on the public roster. Processing, data entry, and system syncing all contribute to this gap — especially during nights, weekends, or periods of high booking volume.
Known Limitations
| Limitation | What It Means for Users |
|---|---|
| Booking-to-posting delay | A recently arrested person may not appear on the roster for several hours after intake. |
| Release removal | Once an inmate is released, their record is typically removed from the roster quickly. The roster reflects current custody, not historical bookings. |
| No archive function | The public roster is not a searchable archive of all past bookings. Older records may require a formal records request to the Sheriff's Office. |
| Data entry errors | Misspelled names or transposed booking numbers can cause a record to be missed in a search. |
| Transfers | Inmates transferred to another facility or to state custody may no longer appear on the Gallatin County roster. |
If you need records that are no longer on the active roster, contact the Gallatin County Detention Center directly or submit a public records request to the Gallatin County Sheriff's Office. For sex or violent offender information, the Montana Sexual or Violent Offender Registry is a separate searchable database maintained by the Montana Department of Justice.
