A jail roster is a custody record, not a court docket. Charges listed at booking are allegations, not convictions. Custody status, bond and release details change constantly, so confirm anything time-sensitive with Jefferson County Criminal Justice or the court. Official source: Jefferson County Sheriff's Office. If a record on this page is inaccurate, use our corrections and removal page.
Jefferson County Criminal Justice: address, phone and visiting

Call before you travel. Visitation at Jefferson County Criminal Justice is normally scheduled in advance and may be video-only, bonding hours can be shorter than the lobby's opening hours, and both change without much notice. The desk can also confirm whether someone booked in the last few hours is in custody, which a roster sync cannot do.
The federal facility dataset lists Jefferson County Criminal Justice with 24 beds as recorded in 2018, while 19 people appear on the roster published today. Read those two numbers side by side rather than as an occupancy rate: rated capacity is not a live figure, jails open and close housing units, and a roster counts everyone booked into the facility including people being held for other agencies.
Facility details from the DHS HIFLD Prison Boundaries dataset, last recorded 2018-03-12. We publish them as-is and do not independently verify them; if something here is wrong, tell us and we will correct it.
What this roster shows right now
Of the 19 people currently listed in Jefferson County, the most common reason recorded is warrant at 47% of records, followed by drug offence (21%) and probation or parole violation (16%). A bond amount is published for 58% of these records, with a median of $25,000. The most recent booking on file is dated 2026-10-13.
Recent bookings in Jefferson County
Counting from the latest sync on 2026-10-13, 1 person was booked into Jefferson County Criminal Justice within a day, and 3 within the past week — that is 16% of everyone currently listed. Among the last day's bookings the most common recorded reason is assault or violence.
A high share of recent bookings means the roster turns over quickly and a name can appear and disappear within days. If you are looking for someone booked in the last few hours, they may not be in this sync yet — the booking desk is the only real-time source.
Figures are recomputed from Jefferson County's own roster at every sync and describe allegations recorded at booking, not convictions. Categories are derived from published charge text, and a record can fall into more than one. See the national data report for method and comparison.
What to do with this information
Posting bond in Jefferson County
Bond is set by a judge, usually at a first appearance within about 24 to 72 hours of booking. Until a bond amount is set, no one can be released. Once it is set you generally have two options: pay the full amount in cash directly to the detention center, which is refundable at the end of the case, or pay a licensed Montana bail bondsman a non-refundable fee, typically around ten percent, to post the bond for you. Ask the jail which payment methods it accepts and whether bonding hours are limited.
Sending money to someone in custody
Most county jails use a third-party commissary vendor rather than accepting cash at the desk. You will normally need the person's full legal name and booking number, both shown on the roster above. Funds usually appear on the account within a few hours and are used for commissary, phone credit and messaging. Vendor fees vary, so check the amount charged before confirming a deposit.
Phone calls, mail and visitation
Calls are placed by the person in custody, not by you, and are recorded. Visitation is often scheduled in advance and may be video-only. Physical mail is inspected, and many facilities reject anything other than plain letters on white paper. These rules differ from county to county and change often, so verify them with Jefferson County Criminal Justice before making arrangements.
Finding the related Jefferson County court case
The roster shows custody, not court proceedings. To follow the case itself, including hearing dates, filings and final disposition, you need the Montana court record system for Jefferson County. Search using the person's full legal name and, where possible, date of birth or case number.
If the person is not on the roster
They may have been released, transferred to another facility, held by a different agency, or booked too recently to appear in the latest sync. People serving longer sentences are usually held by the state department of corrections rather than a county jail, and appear in a separate state system.

Common questions
How do I find out if someone is in Jefferson County jail?
Search the roster on this page by name, booking number or listed charge. The roster reflects the most recent successful sync from the official Jefferson County Criminal Justice booking source. If the person was booked in the last few hours, or has already been released or transferred, call the jail to confirm.
How do I post bond for someone in Jefferson County?
Bond is set by the court, not by the jail. Once a bond amount appears it can usually be paid in cash at the detention center, or through a licensed Montana bail bondsman who charges a non-refundable fee. Confirm accepted payment methods and bonding hours with the jail before travelling.
What is the address and phone number for Jefferson County Criminal Justice?
Jefferson County Criminal Justice is at 110 S Washington St, Boulder, MT 59632. The published phone number is (406) 225-4091. Call ahead to confirm visiting hours, bonding hours and what you are allowed to bring, because those rules differ by facility and change often.
Why does a charge appear if the person has not been convicted?
A jail roster is a custody record. Listed charges are the allegations recorded at booking. They are not convictions, they can be amended or dropped, and every person is presumed innocent unless a court finds otherwise.
How current is this Jefferson County roster data?
The latest successful sync was 2026-10-13 19:30 UTC. Custody status changes continuously as people are booked, released or transferred, so treat any time-sensitive detail as provisional until confirmed with the jail or court.
Other counties named Jefferson
8 other states we cover have a county of the same name. County names repeat across states, so confirm the state before assuming someone is not in custody.
Other Montana county jail rosters
Booking often happens in the county where the incident occurred rather than where the person lives, so neighbouring counties are worth checking when a search comes up empty.
