Billings Jail Roster: Yellowstone County Inmate Search And Detention Guide (2026)

Locating an individual who has been arrested or is currently detained in Billings, Montana, requires navigating the regional public safety database. The primary adult holding facility for this region is the Yellowstone County Detention Facility (YCDF). This guide outlines how to access the official Billings jail roster, interpret inmate records, coordinate visitation, and navigate the booking and bail processes in compliance with Montana law and local administrative guidelines.

This guide focuses exclusively on the adult detention facility operated by the Yellowstone County Sheriff's Office in Billings, Montana. It does not cover federal holding centers, state prisons, or juvenile detention facilities unless specifically noted.

Understanding the Yellowstone County Detention Facility in Billings

The Yellowstone County Detention Facility (YCDF), located in Billings, Montana, serves as the primary correctional institution for the county. It houses individuals awaiting trial, those sentenced to misdemeanor terms, and state inmates temporarily held for court proceedings. Managed by the Yellowstone County Sheriff's Office, the facility operates under strict state and federal administrative regulations to ensure safety, security, and public access to legally mandated public records.

The YCDF is a modern detention center designed to handle booking, medical screening, housing, and court video-arraignments. Because Billings is the largest municipal area in Montana, the jail roster experiences high daily turnover. Understanding how the booking pipeline works helps clarify why a recently arrested individual may not immediately appear on the public roster.

How to Access and Search the Billings Jail Roster Online

The online Billings jail roster is a public record updated continuously to reflect new bookings, releases, and housing transfers. To search for an inmate, you must use the official portal provided by the Yellowstone County Sheriff's Office.

Step-by-Step Roster Search Procedure

1. Access the Official Portal: Navigate to the Yellowstone County Sheriff's Office public portal and select the Active Inmate Search tool.
2. Input Search Criteria: Enter the last name of the individual. For broader searches, you can enter the first initial, though typing the full, legally documented name yields the most accurate results.
3. Verify Identity via the Profile: Click on the individual's name to open their custody profile. Verify their identity using their date of birth, age, physical description, and booking photograph (mugshot).
4. Review Charge Details: The profile lists active charges, the arresting agency (such as the Billings Police Department or the Montana Highway Patrol), the booking date, and the assigned bond amount.

Information Provided on the Public Roster

The online directory provides specific data fields approved for public release under Montana's public records laws:

• Booking Number: A unique administrative identifier assigned to the individual for their current stay.
• Full Legal Name and Mugshot: High-resolution booking photograph alongside the legal name used during booking.
• Arresting Agency: The specific law enforcement department that initiated the custody (e.g., Billings Police Department, Yellowstone County Sheriff, or State Highway Patrol).
• Bond Amount and Type: Specifies whether the bond is cash-only, surety, or if the individual is held on a "no-bond" status (often seen in felony probation violations or pending initial appearance).
• Current Charges: Standardized legal terminology representing the alleged violations of the Montana Code Annotated (MCA).

Navigating administrative channels at the detention facility requires contacting the correct department directly. The table below outlines verified contact details, operational hours, and service statuses for the Yellowstone County Detention Facility.

Posting Bail and Securing Release at YCDF

When an individual is booked into the Billings jail, a judge typically sets a bail amount during the initial appearance (arraignment), which usually occurs within 24 to 48 hours of arrest. If the offense is a standard misdemeanor with a pre-set bond schedule, bail may be posted immediately.

Methods of Posting Bail

There are three primary avenues for securing an inmate’s release through bail payment:

Cash Bonds

A cash bond requires the full amount of the bail to be paid directly to the court or the detention facility. This money is held as collateral to guarantee the defendant's appearance at all future court dates. If the defendant attends all hearings, the cash is returned at the resolution of the case, minus standard court administrative fees. If the defendant fails to appear, the entire cash bond is forfeited to the state.

Surety Bonds (Bail Bondsmen)

If the total bail amount is financially unfeasible, family members or friends can contact a licensed bail bondsman in Billings. The bondsman charges a non-refundable fee (typically 10% of the total bail amount under Montana regulations). The bondsman then provides a financial guarantee to the court for the remaining balance. The indemnitor (the person signing for the bond) may need to provide collateral, such as real estate or vehicle titles, to secure the bond.

Property Bonds

A property bond involves pledging real property (such as land or a home) located within Yellowstone County to the court as collateral. The equity in the property must generally be worth at least twice the amount of the bail. This process requires a property appraisal, a title search, and a formal court hearing, making it a much slower option than cash or surety bonds.

Inmate Communications: Phone, Mail, and Visitation

Maintaining contact with incarcerated individuals is subject to strict security protocols managed by the Yellowstone County Detention Facility. All communications are subject to monitoring and recording, with the exception of verified legal counsel communications.

Telephone Accounts and Communication Portals

Inmates cannot receive incoming phone calls. To make outgoing calls, they must use the facility-approved communications provider.

Inmate Telephone and Communication Rules

Prepaid Calling Accounts Family members and friends can set up prepaid accounts through the facility's contracted telecom provider (such as Telmate or GettingOut). This allows the inmate to call specific phone numbers directly, with the costs deducted from the funded account balance.

Debit Phone Accounts Inmates can purchase phone debit minutes directly using funds from their commissary accounts. These minutes can be used to call any approved phone number.

Call Recording Advisory Every call made from the facility is recorded and monitored by detention staff. Information shared during these calls can be used by prosecutors in court. Discussing case details over jail phone lines is strongly discouraged.

Mail Guidelines and Restrictions

To prevent contraband from entering the secure facility, all physical mail must comply with strict rules. Mail that violates these rules is returned to the sender or disposed of as contraband.

• Addressing Format: Mail must be addressed to the inmate's full legal name, including their booking number, sent to: Yellowstone County Detention Facility, 3165 King Avenue East, Billings, MT 59101.
• Mail Type Restrictions: Many facilities require personal correspondence to be written on plain white postcards. Holiday cards, double-layered cards, and envelopes with stickers, glue, glitter, or perfume are strictly prohibited.
• Photographs: Inmates may receive limited printed photos (usually maximum size 4x6 inches). Photos must not contain nudity, gang references, drug references, or depictions of weapons.

Visitation Procedures

The YCDF primarily utilizes video visitation systems to maintain facility security. On-site video visits are conducted using terminals in the public lobby, while remote video visits can be accessed from any internet-connected computer or mobile device equipped with a camera.

All visitors must register in advance through the designated online communication portal, provide valid government-issued photo identification, and schedule their visits at least 24 hours in advance. Visitors must adhere to a strict dress code, and any inappropriate behavior during a video visit will result in immediate termination of the session and suspension of visiting privileges.

When seeking information about an arrestee or a past criminal record in Billings, users can choose between checking the online jail roster or requesting formal records. The table below outlines the differences in accessibility, depth, and processing times.

Frequently Asked Questions

How often is the Billings jail roster updated?

The Billings jail roster is updated automatically throughout the day, typically every 15 to 30 minutes, to reflect new bookings, cell transfers, and releases. However, there may be an administrative delay during high-volume booking periods or when an inmate is undergoing medical evaluation before being cleared for general housing.

Can I look up past mugshots or historical inmate records online?

No. The active Billings jail roster only displays information for individuals currently housed in the Yellowstone County Detention Facility. Once an inmate is released, transferred to a state prison, or posted bail, their profile and mugshot are removed from the public lookup tool. Historical criminal histories must be requested through the Montana Department of Justice's criminal background check portal or the local Clerk of Court.

What should I do if an arrestee is not showing up on the roster?

If someone was recently arrested but does not appear on the online roster, they may still be in the booking and intake phase, which can take several hours. During booking, inmates undergo fingerprinting, medical screening, and identity verification. Alternatively, the individual may be held at a different facility, or they may have been released on their own recognizance before booking was finalized. You can call the Jail Administration line at (406) 256-6910 for direct confirmation.

How can I send money to an inmate's account at the Yellowstone County jail?

You can deposit funds into an inmate’s commissary account using three main methods: using the electronic kiosk located in the public lobby of the Yellowstone County Detention Facility (which accepts cash and credit cards), using the approved online payment processor portal, or sending a certified government money order through the mail. Personal checks are not accepted.

Are there charges to search or view the Billings jail roster?

No, searching the Billings jail roster is a free public service provided by the Yellowstone County Sheriff's Office. Be cautious of third-party websites that demand payment or subscription fees to view arrest records, as these are private entities that scrape public data and may present outdated or inaccurate information. Always use the official county portal for the most accurate and current information.

If you or a family member requires immediate assistance regarding a pending court appearance, legal defense, or formal bail negotiations at the Yellowstone County Detention Facility, contact a licensed Montana bail bondsman or the Billings Public Defender's Office. Ensure you have the inmate's full legal name and date of birth ready to expedite your request.
