Montana Department of Corrections (MT DOC)

The Montana Department of Corrections (MT DOC) operates the state's prisons and supervises people on probation and parole across Montana. For families, the department's rules are what decide how you find a loved one, get approved to visit, write, call, and send money — and Montana ties visitation approval to the ability to send funds, uses digital mail across its main facilities, and requires an OKTA account to interact with several of its online services. This guide brings the essentials together so you can stay connected without learning every rule the hard way.

About the Montana prison system

Montana operates state prisons including Montana State Prison, Montana Women's Prison, Pine Hills Correctional Facility, and the Riverside facility, along with community-corrections programs across a geographically large state. The Helena headquarters is an administrative office where policy questions go, while mail and money are handled through the department's designated systems and the specific facility. Every incarcerated person is assigned a DOC number that identifies them throughout the system and is required for visits, mail, and deposits, so noting it early saves time on every later step.

Because Montana is so large, distance is often the family's biggest practical challenge, and confirming exactly where your person is held before acting is the habit that saves the most frustration. If you are not sure which facility holds them, our guide on how to find someone in jail or prison explains how to trace an incarcerated person through official records, and you can search their name directly on AllRecentArrests.us to see their facility and status. Treat the DOC number rather than the current address as the constant you build everything around, and set up your OKTA account early since you will need it for both visits and online deposits.

Visitation process and timings

Visiting in Montana requires approval, and approval takes time: up to 90 days from when you submit the application. Family and friends must be approved before they can send funds, so getting approved is the gateway to everything else, not just to visits. The process begins by creating an OKTA account — the state's identity system — and then completing the online visitation application; once approved, you schedule visits online in advance. That single 90-day window is the reason to start the paperwork immediately, well before you plan to visit or send money.

Because approval takes so long and Montana's institutions are far from most of the state's population, planning matters. Our complete prison visitation guide covers getting approved, dress codes, and what to expect at the checkpoint, and if the drive is too far to make often, our walkthrough on setting up a video visit with an inmate explains how to connect from home where video visits are offered. Always confirm the specific facility's current visiting rules and hours before you travel, since a wasted trip across Montana is a hard lesson.

How to send money to an inmate in Montana

Montana has specific rules for both mailed and online deposits, and following them exactly is the difference between money that reaches your person and money that is returned. By mail, use a U.S. Postal Service money order (Montana requires USPS money orders, and the prison must receive it within 20 days of the purchase date), send it in an envelope with your full name and address in the top left corner, and address it "Attn: Mailroom Staff" with the inmate's full name and DOC number. Critically, do not enclose letters, sticky notes, photos, or anything else in the same envelope — if you send checks, money orders, or cashier's checks along with personal correspondence, all items are returned to the sender.

Online, deposits go through inmatetrust.mt.gov, and you need an OKTA account to use the service. Our overview of how to send money to an inmate compares the common deposit methods and posting times so you can pick the option that works best for your household. Sending a slightly larger amount less frequently usually beats many small deposits, and following Montana's envelope rules to the letter is what makes the mailed route reliable.

Mail, care packages, and phone calls

Montana has moved to digital mail for its main facilities: all inmate personal mail at Montana State Prison, Montana Women's Prison, Riverside, and Pine Hills Correctional Facility is scanned at an off-site processing facility and delivered digitally to inmates on their assigned tablets, rather than handed over on paper. That means the letter you send is opened, scanned, and destroyed at the processing center, and your loved one reads a digital copy on their tablet. Keep letters plain, in dark ink on standard paper so they scan cleanly, and avoid stickers, glitter, unusual pens, and anything that will not reproduce well. Our breakdown of how to send mail to an inmate covers the address format and common rejection triggers.

Because you cannot mail packages directly, funding the account so the inmate can buy from commissary is the way to help with goods, and our explainer on how prison commissary works shows what a funded account buys. Phone service lets the inmate place calls to numbers on their approved list, so set up and fund a prepaid account tied to your number; under the 2026 FCC rate caps, per-minute rates have dropped sharply, and our guide to calling an inmate explains account setup and cost control. Legal mail is handled separately from digital-scanning and is opened only in the inmate's presence, so mark it clearly.

Legal mail, emergencies, and avoiding scams

Legal or privileged mail from an attorney or a court is handled separately from ordinary correspondence and is generally opened only in the incarcerated person's presence, so keep legal documents out of personal letters and mark them properly. For emergencies such as a death, serious illness, or birth in the family, the reliable route is to call the facility and ask how to get an urgent message to the person or their case manager, rather than trying to reach them directly, and keeping the DOC number handy makes that call go faster. If you are worried about a loved one's medical care, mental health, or safety inside, contact the facility's staff directly, explain the situation clearly, and keep a written record of who you spoke with and when.

Be cautious, too, about where you get information and send money. The MT DOC inmate search and the department's named deposit vendors are the authoritative channels, so paying an unfamiliar third-party site to "locate" a person or forward a deposit is a common way families lose money for something the state provides directly. When a rule you read online conflicts with what the facility tells you, trust the facility, and confirm anything important by calling (406) 444-3930 or the specific institution before you act on it. A little skepticism about paid third-party services protects both your wallet and your loved one's account balance across the length of a sentence.

Staying consistent and preparing for release

Whatever mix of calls, mail, and visits you settle into, consistency matters more than any single grand gesture, and steady support is one of the most valuable things a family can offer someone inside. A predictable call, a letter that arrives on a schedule, and an occasional visit give the person something reliable to count on through a hard stretch, and they keep you informed about how they are doing as the sentence progresses. Keeping your own records — the identifying number, current facility, deposit receipts, and any court or parole dates — smooths every later step and prevents most of the delays families run into when someone is transferred.

As a release date approaches, preparation pays off — lining up identification, housing, and income before the day arrives makes the first weeks home far less chaotic. Our reentry guide for life after prison covers those first steps, our guide to finding work after prison addresses fair-chance hiring, and many returning citizens qualify for help through SNAP, Medicaid, and TANF soon after release. If you are supporting a household through an incarceration, our overview of financial help for families of incarcerated people lists resources that can ease the strain while your person is away.

The one Montana-specific habit worth building early is treating every money envelope as its own single-purpose mailing — nothing but the money order and the required addressing, no personal notes, no photos — because mixing them is the fastest way to have both the payment and the letter returned to you. Keep a separate rhythm for letters (which are scanned digitally at Montana's main facilities) and for deposits, and set up your OKTA and inmatetrust.mt.gov accounts once so you never have to rebuild them under pressure. When guidance you read online conflicts with what MT DOC tells you directly, trust the department.

Montana contracts out a large share of its custody

The department lists contracted secure facilities alongside the prisons it runs directly. In a state as large and thinly populated as Montana that arrangement is structural rather than incidental: beds are where they can be contracted, not necessarily where families live. If your family member is moved, the operator of the receiving facility may be a private company or a county, while the department remains responsible for them.

The services provided here are state-run secure facilities, contracted secure facilities and probation and parole supervision. That is a clinical remit rather than a custodial one — people are here because of a medical or behavioural health need, not because this is where they are held.

Where Montana contracts beds — including out of state

Because this record is not itself a custody facility, the numbers worth knowing belong to the two that are. The most recent federal jail census, covering 2026, counted them separately:

• Crossroads Correctional Center, Shelby, Montana
• Dawson County Correctional Center, Montana
• Tallahatchie County Correctional Facility, Tutwiler, Mississippi

The department contracts with a regional prison and three private facilities, with roughly 1,500 people placed among them. About 600 Montana prisoners are held at Tallahatchie County Correctional Facility in Tutwiler, Mississippi — around 1,700 miles from Helena. A transfer there changes nothing about a sentence but changes everything about whether a family can visit.

Those are census figures for a single reporting year and are now several years old, so treat them as the scale of each facility rather than a current count. Neither figure describes this record — this address is the hospital, and it holds no one on its own authority.

What records still exist for the Montana Department of Corrections

Closing a prison does not erase its statistical record. The department continues to publish pre-closure reports for this institution, including interactive dashboards covering population and placement, published data and statistics reports and departmental policy directives, including the directive governing facility design capacity.

These are worth knowing about if you are reconstructing a timeline — confirming when someone was held here, what the conditions and population were at the time, or supporting a claim that depends on how the institution was operating. They are statistical rather than individual, so they will not contain a named person's file; for that you need a records request to the department rather than a published report.

Who runs the Montana Department of Corrections

The institution's main line is (406) 444-3930. Use it for anything urgent — a medical emergency, a safety concern, confirming whether visiting is running — and ask for the watch commander or the shift supervisor rather than leaving a message with whoever answers.

What this department operates

The department lists 20 adult institutions. This record is the department itself rather than any one prison, so it has no beds, no visiting room and no warden of its own — which is why the practical details you need always belong to a specific institution, not to headquarters.

With a single women's prison for the whole state, a woman sentenced in Montana has one destination regardless of where her family lives — and Montana is the fourth largest state by area.

The system comprises 20 facilities across the state, led by Montana State Prison for men at Deer Lodge and the Montana Women's Prison at Billings, which holds around 240 women. Pine Hills Correctional Facility at Miles City is the department's only state-operated long-term facility for adjudicated youthful offenders, taking young people aged 10 to 17. Knowing the list is more useful than it looks: a transfer is announced by institution name, often with no explanation of where that is or how far you will now have to travel.

That distinction matters when you are chasing an answer. Department policy sets the framework — visiting eligibility, approved vendors, grievance procedure — but the schedule, the phone number, and the person who can actually help are all at the institution holding your family member. Start by confirming which prison that is, then work with that facility directly.

How to find someone in this department's custody

The department's official search tool is the department's offender search, at offendersearch.mt.gov/conweb. Because Montana places people in contracted facilities as well as its own, the department search is the only reliable way to establish where someone is — a county roster will not show a person once they are in state custody, and a contracted facility may not publish a roster at all.

Your first steps

If someone you love has just entered the Montana system, focus first on the essentials: confirm which facility holds them and write down their DOC number, create your OKTA account and submit the visitation application immediately because approval takes up to 90 days, and plan a first deposit — either a USPS money order sent alone in its own envelope or an online deposit through inmatetrust.mt.gov once your OKTA is set up — so calls and commissary are possible. Remember that mail is scanned digitally at Montana's main facilities and that mixing money and letters gets everything returned. When a policy you read online conflicts with what the facility says, trust the facility.
