In fact, it always has over 500 inmates housed there, and has been known to get as full as having 620 men and women there at one time. Yellowstone County has come a long way since their early days when their first jail was constructed in 1884 at 401 N. 27th in Billings, which is currently the Yellowstone Art Museum.
The current address of the Yellowstone County Detention Facility is 3165 King Ave. in East Billings. You can reach them by phone 24 hours a day by calling 406-256-6881, and also by email. If you want to find out about an inmate, go the official Inmate Jail Roster to search for them, although the jail, while they do provide information about the inmate's criminal charges, does not provide the public with mugshots.

The original design of the facility allowed for the safekeeping of 174 inmates on a ten-acre site, with the possibility of future expansion. The 430 bed detention facility is considered a regional medium-security jail, which houses pre-trial offenders and those sentenced to less than one year. There are some inmates that have been sentenced to longer terms, but are awaiting transport to state or federal prison, or to an ICE Detention Center.
The overcrowding issue is not just that there's not enough beds, but that they can't get enough staff. Every day, the decision must be made to let inmates out that should be staying in jail due to their danger to the community. But until the voters approve funding for an expanded facility, which could cost $75 million or more, the issue will remain in Billings.

Option 1 - Dropping Money at the Jail
Bring money to the jail in person.
Either the jail personnel will process the Inmate Account payment or you will use a Jail ATM self-serve kiosk in the lobbies that accepts cash, debit or credit cards.
Option 2 - Deposit Inmate Money Online
Yellowstone County Detention Facility uses Jail ATM to process all online deposits to an inmate's account. The company charges you a small fee for doing so, but the fee probably isn't as much as gas and parking would cost to take it to the jail in person.
Option 3 - Mail the Inmate Deposit to the Jail
Mailing a deposit takes more time to process than the other methods but can be done if you live too far away to bring it in person and you don't have a debit/credit card for online deposits. Never send cash. Always send a Money Order from the US Post Office, a reputable bank or Western Union. Call the Yellowstone County Detention Facility first as they may want you to do this online or at the jail kiosk instead.
Make the Money Order out to the payee the jail names (check with the jail first) and put their Inmate ID# in memo section of the Money Order. Never mail cash or a personal check.
