Billings MT Jail Roster: Yellowstone County Inmate Search & Booking Guide (2026)
Locating an individual who has been arrested or held in custody in Billings, Montana requires accessing the official public records maintained by the Yellowstone County Detention Facility (YCDF). The City of Billings does not operate a separate municipal long-term holding facility; instead, all arrests made by the Billings Police Department, Yellowstone County Sheriff’s Office, Montana Highway Patrol, and federal law enforcement agencies within county limits are processed directly through the YCDF.
This comprehensive 2026 guide provides updated procedures for navigating the active inmate roster, searching public booking records, understanding bail conditions, depositing canteen funds, and scheduling video visitations.
Navigating the Yellowstone County Detention Facility Online Inmate Search
The Yellowstone County Sheriff’s Office hosts a publicly accessible online inmate roster updated continuously throughout the day. This search portal serves as the primary tool for legal representatives, bail agents, family members, and crime victims seeking real-time custody status, pending charges, and bond amounts.

When reviewing an individual entry on the Billings jail roster, the portal displays verified public safety data elements mandated under Montana public records laws:
- Full Legal Name and Booking Identifier: Primary demographic details alongside a unique YCDF booking identification number assigned upon intake.

Understanding the Intake, Booking, and Release Pipeline in Billings
Once a suspect is apprehended in Billings, they are transported directly to the YCDF intake division located at 4315 South 27th Street. The booking pipeline follows standardized law enforcement protocol to ensure subject safety, identity verification, and legal compliance.
[Arrest by BPD / YSO / MHP] │ ▼ [Transport to YCDF (4315 S 27th St)] │ ▼ [Medical Screening & Property Inventory] │ ▼ [Fingerprinting, Mugshot & Warrant Check] │ ▼ [Data Upload to Active Public Roster] │ ▼ [Initial Hearing / Bond Posting / Pre-Trial Release]
During medical screening, booking officers evaluate the detainee for immediate health conditions, substance intoxication, or mental health emergencies requiring transfer to local medical centers such as Billings Clinic or St. Vincent Healthcare. Following medical clearance, officers inventory personal property, record fingerprints into national databases, take standard intake mugshots, and execute mandatory warrant checks.
Pre-Trial Initial Appearances and Arraignments
Arrestees who cannot immediately post a pre-set bond are scheduled for an initial court appearance. In Yellowstone County, initial appearances generally occur within 24 to 48 hours of booking (excluding weekends and legal holidays).
- Billings Municipal Court: Handles misdemeanor offenses, traffic citations, and local municipal ordinance violations occurring within city limits.
- Yellowstone County Justice Court: Holds jurisdiction over county-level misdemeanors, initial appearances for felony offenses, and preliminary bail hearings.
- 13th Judicial District Court: Oversees felony prosecutions, grand jury indictments, complex criminal litigation, and post-arraignment bond modification hearings.

Bail and Bond Posting Guidelines at YCDF
Posting bail allows a detainee to be released from custody while agreeing to attend all future scheduled court proceedings. In 2026, several payment structures and release mechanisms are operational at the Yellowstone County Detention Facility.
Types of Bonds Accepted
Cash Bond (Full Amount) Paying the complete cash amount directly to the jail or court. Cash bonds are fully refundable at the conclusion of judicial proceedings, provided the defendant attends all mandatory court dates, minus standard administrative court processing fees.
Surety Bond (Bail Bondsman) Engaging a state-licensed Montana bail bondsman when full cash amounts are unavailable. The bondsman charges a non-refundable fee (typically 10% of the total bail figure) and posts a legal guarantee with the court for the remainder.
Property Bond Pledging real property located within Yellowstone County as collateral to secure release. The equity in the property must usually equal or exceed twice the posted bond amount and requires formal court approval and title review.
Recognizance Release (OR) / Pre-Trial Services Release granted by a judge without monetary deposit based on the detainee's community ties, low flight risk, and lack of violent criminal history. Individuals may be placed under supervision with Billings Pre-Trial Services, requiring periodic check-ins and random drug testing.

Inmate Communications, Canteen Funds, and Mail Protocols
Maintaining contact with incarcerated individuals at YCDF requires strict adherence to security protocols governing phone systems, video visits, digital messaging, and physical mail processing.
Depositing Funds into Inmate Trust Accounts
Detainees use trust funds (canteen balances) to purchase personal hygiene products, over-the-counter medications, writing materials, and approved commissary items. Friends and family members can deposit funds into an inmate’s account through three primary methods:
- Lobby Kiosk: A secure automated payment kiosk located inside the public entrance lobby of the YCDF at 4315 S. 27th St. Accepts cash, debit cards, and major credit cards.
- Online Payment Portals: Approved third-party vendor platforms (such as TouchPay or GettingOut) accessible via web or mobile application using the detainee's full legal name and inmate booking ID.
- Toll-Free Phone Deposits: Automated telephone payment processing systems operating 24 hours a day.
Calling, Video Visitation, and Mail Policies
Inmates cannot receive inbound telephone calls. All outgoing calls are placed as collect calls or funded through pre-paid inmate phone accounts managed via the county's designated telecommunications provider.
Important Mail Regulations All incoming non-legal mail is subject to physical and electronic inspection for contraband. Mail must be addressed with the inmate's full legal name and booking ID number to:
Yellowstone County Detention Facility Attn: [Inmate Full Name & Booking ID] 4315 S. 27th Street Billings, MT 59101
Polaroid photographs, hardbound books, mail containing stickers, glue, glitter, or unverified liquids are strictly prohibited and will be returned or destroyed. Legal mail from licensed defense counsel is opened strictly in the presence of the detainee.
Remote and onsite video visitation services are available. Remote video visits must be scheduled at least 24 hours in advance through the authorized vendor portal, while onsite lobby visits must strictly adhere to weekly visitation schedules categorized by housing units.
