If you have someone locked up in Montana, two questions come up fast: what can they buy, and what can you send. The answer depends on where they are held, and in Montana that is not always obvious. Here is how it works, so you are not guessing or wasting money.
One thing worth saying up front. The most dependable way to stay in touch with anyone inside is the mail. A letter and a few printed photos, where photos are allowed, get through when an account is short or when a facility takes no packages. Treat that as your baseline and the rest as extra.
Montana state prisons (DOC)
In a DOC facility there is no cash. Money goes onto the inmate's trust account, and they spend it at the commissary on snacks, hygiene items, and similar basics.
Montana runs its own online deposit system, the Inmate Trust Account Deposits service on the state's website, rather than handing the job to a private money-transfer company. It covers Montana State Prison in Deer Lodge, the Montana Women's Prison, the Crossroads Correctional Center in Shelby, and the Dawson County Correctional Facility. A few Montana rules are stricter than most states, so read these closely:
You generally must be on the inmate's approved visiting list to send money. The per-transaction limit is $250, and funds have a three-day holding period before they are available. To set up the online account you need the last four digits of your Social Security number. If you mail funds instead, the state accepts only a cashier's check or a U.S. Postal Service money order, never cash or a personal check, capped at $250, and it has to be received within 20 days of the purchase date with the envelope postmarked from the area where the approved sender lives. The state also deducts court-ordered obligations from incoming money before it lands in the account.
Care packages for DOC residents
Montana state facilities do not run a family care-package program. The way you provide items is to fund the trust account so your person can buy what they need from the commissary themselves.
That leads to the one warning worth repeating. If anyone tells you to ship a package to a Montana state facility, verify it with the facility first, because outside boxes are generally refused and the commissary is the real channel.
Where is your person actually held
This is the part that trips up Montana families. A Montana state sentence does not always mean a traditional state prison. Because of crowding, the state houses people across a mix of places: the two main state prisons, a privately run prison in Shelby, a regional facility in Glendive, county jails while people wait for a bed, and even private prisons in other states like Arizona and Mississippi under contract. Confirm exactly where your person is physically held before you set up deposits, because the facility decides the rules and the mailing address.
Montana county jails
County jails are their own world, and in Montana they also hold some state inmates waiting for placement. Each county runs its own deposit and commissary contracts, so the vendor and rules change from county to county.
A couple of real examples. Yellowstone County in Billings, the largest jail, funds a trust or commissary account through Inmate Canteen online or a lobby kiosk, or by a money order, no cash or checks, mailed to the inmate with "Attention Mail Officer" in the address, or it comes back. It keeps a separate communications account for phone, video, and messages, with transfers allowed from the trust account. Cascade County in Great Falls uses Access Corrections and takes a money order or cashier's check, no cash or personal checks. City lockups often have no package program and allow commissary only.
The takeaway is simple: never assume a county jail uses the same vendor or rules as the state. Pull up that specific jail's page and confirm the deposit vendor, the spending cap, the cutoff, and the package policy before you send anything.
Federal custody and Montana
Montana has no federal Bureau of Prisons facility. Someone from Montana with a federal sentence is held at a Bureau of Prisons facility in another state, so your first move is the inmate locator to find exactly where. One local wrinkle: people in federal custody before sentencing are sometimes held in Montana by the U.S. Marshals Service, including at the private prison in Shelby, rather than by the Bureau of Prisons. Once someone is sentenced and assigned to a Bureau facility, the federal rules apply, and they are the same nationwide.
Funding works through the federal Trust Fund. You can send money online or by app through JPay, mail a money order or cashier's check made payable to the Federal Bureau of Prisons with the inmate's full name and register number on it to the national lockbox, or use Western Union. No cash, no personal checks.
The commissary is the only store in the federal system, and the inmate shops it in person on an assigned day each week, usually tied to their register number. You fund the account; they pick from what is in stock. The shelves cover food and drink mixes, hygiene, a limited clothing selection, stationery and stamps, some over-the-counter medicine, and at some facilities approved electronics.
On the money, general population inmates can spend up to $360 per month, and that limit resets monthly. Stamps, phone credits, and over-the-counter medicine generally fall outside the cap. In November and December the limit typically rises to $410 for holiday shopping. An inmate who refuses the Inmate Financial Responsibility Program gets knocked down to roughly $25 per month.
Federal care packages are not allowed. The Bureau prohibits outside food, clothing, or hygiene packages from family or friends. The narrow exceptions are publications shipped directly from a publisher or approved retailer, religious items cleared through the chaplain, and legal materials from an attorney or court.
For messaging, the federal system uses an email tool families reach through the CorrLinks portal, reviewed by staff and not confidential. To find someone in federal custody, use the Bureau of Prisons inmate locator, which searches by name or register number.
Staying connected
Montana takes more homework than most states, because your person could be in a state prison, a private or regional facility, a county jail, an out-of-state prison, or federal custody, and each has its own money and package rules. The first job is always to confirm exactly where they are. The one constant through all of it is the mail. A letter reaches almost anyone inside, which makes it the most reliable way to show up for your person while you sort out the rest.
