The Yellowstone County Detention Facility is a medium-security detention center located at 3165 King Ave E in Billings, MT. This county jail is operated locally by the Yellowstone County Sheriff's Office and holds inmates awaiting trial or sentencing. Most of the sentenced inmates are here for less than two years. Yellowstone County accepts inmates from surrounding towns, municipalities, the US Marshal's Service and the Billings Police Department who do not have their own long-term lock-up.

There are new detainees delivered to the jail daily, you can see arrest records here. Some are released after putting up bail, are released to a pretrial services caseload, are placed under supervision by a probation agency, or are released on their own recognizance with an agreement to appear in court. If there is no release, the inmate must wait here at the jail for their court appearance as a guest of the County, getting a bed and three square meals.

Trustees are inmates who work in the jail as cooks, as orderlies for the staff, in the laundry or in the commissary. The trustees are paid a very small amount for their time and some jail gives the trustees a few days off their sentence in exchange for their work.

When an inmate arrives in jail they are put together in a large holding cell with other inmates in the intake. While in intake they are under heightened observation. Violent and out of control inmates are segregated.

Can I Get Work Release?

Work release is when you are released from jail during the day so that you can go to work. At the end of the day, you return to jail for the night. There are a number of requirements to be able to get into the work-release program. Most programs require your employer to fill out some paperwork. If you want to get into the work release program then apply prior to being sentenced to jail. This will minimize the amount of time you spend in jail waiting to get into the program.

Since you are paying for those calls don't make it a habit of accepting collect-calls, they are over $15 each.
