MT DOC - Montana State Prison basic information to help guide you through what you can do for your inmate while they are incarcerated. The facility's direct contact number: 406-846-1320

The inmates housed at Montana St Prison located at 400 Conley Lake Rd in Deer Lodge, MT are placed according to their custody level (determined by a number of factors including the past criminal history and the length of their sentence). There are ample educational and vocational training programs for all inmates, especially ones that show a willingness to learn new things that will prepare them for a better life when they are released. The mission is to promote and prepare the offender to leave in better shape than when they arrived, giving them the best chance to never come back and thus lower the state's recidivism rate.

Montana State Prison (MSP) is located in Deer Lodge Montana and is the largest correctional facility in the state, housing nearly 1,500 male inmates in a 68-acre compound designed to handle all custody levels. This facility is responsible for six custody levels, minimum I, minimum II, medium I, medium II, maximum and closed custody. Offenders are housed in one of three compounds depending on their security level. Inmates are secured by two fences and a large wall with razor wire. Montana State prison is also responsible for a 192-bed work and re-entry center that houses minimum custody inmates just outside the main perimeter fence. Inmates in this unit work on a ranch and dairy farm as part of the Montana Correctional Enterprises.

Montana State Prison and its staff of about 640 uniformed and non-uniformed employees serve the citizens of Montana by providing a secure correctional environment that supports public safety by encouraging positive offender change.

The prison is divided into three compounds: low side, high side and locked housing. Within those custody levels are different types of supervision. Inmates range from general and special management populations to those with serious mental illness and inmates housed for pre-hearing confinement, detention or those in locked housing due to ongoing or serious behavior management problems.

Montana State Prison uses a unit management structure that is ultimately managed by a warden, four associate wardens and three bureau chiefs. Outside the fenced perimeter is a 192-bed Work and Reentry Center, which houses minimum-custody inmates who work on the 35,000-acre ranch and dairy program operated by Montana Correctional Enterprises (MCE). Together, the prison and MCE provide work for about 70 percent of the inmate population, as well as education, treatment, programming, recreation, religious activities and clinical services to promote the development of self-esteem, an environment that fosters self-improvement and a work ethic that will serve inmates before and after their release.

Inmate Locator

MT DOC - Montana State Prison is a facility in the Montana Department of Corrections. The DOC publishes the names of their current inmates and identifies which of their locations the inmate is being held. Your search should start with the first DOC locator to see if your loved one is there. Begin with the first three letters of the offender's first and last name, it does not have to be spelled exactly.

The second box is the InmateAid Inmate Search. This database of inmates is user-generated content for the purpose of accessing and utilizing any or all of the InmateAid services. If you need our assistance creating your own inmate profile to keep in touch, email us at aid@inmateaid.com and we will assist you in locating your inmate.

As a last resort, you might have to pay for that information if we do not have it. The Arrest Record Search will cost you a small amount, but their data is the freshest available and for that reason, they charge to access it.

  • The visiting form must be filled out completely and accurately.
  • Applicants 18 years and older must submit separate questionnaires.
  • Children less than 18 years of age must be included on the same questionnaire as their parent applicant or court-appointed legal guardian.

  • Mail completed forms to:
    Mail Technicians
    400 Conley Lake Road
    Deer Lodge, MT 59722
  • All visitors are subject to criminal background checks.
  • Visitors may be on only one inmate’s visiting list at a time, unless an exception is granted because both inmates are members of the same immediate family.
  • Within 30 days of receiving a questionnaire, a staff member contacts the inmate in writing to let him know whether a prospective visitor’s application has been approved. A disapproved applicant may appeal the decision by:
    • filling out the appeal section on the disapproval form they receive from the inmate
    • mailing it to the second shift captain within 14 days of the postmark on the notice.
  • Approved visitors must notify MSP of any changes to their name or address. Visitors must notify MSP visiting staff of their updated information at their first visit following the change.

Conditions of visiting

Work crews – Inmates on work crews are expected to arrange their visits after work hours.

Number of visits – Inmates in the general prison population may have four visits each week.

Number of visitors – No more than five people (including children) may visit each inmate at one time. A visitor may visit no more than one inmate at a time unless the visitor has the prior approval of the second-shift captain.

Visiting room capacity – When a visiting room is at maximum capacity, no more visitors are allowed in.

  • As more visitors arrive at the Wallace Building, those in the visiting room are allowed one hour and then visits are terminated for local visitors (those within 45 minutes driving time of MSP).
  • If this fails to address the waiting list in the Wallace Building, ongoing visits for visitors from further away are terminated.
  • Visits will not be terminated less than one hour from the start of the visit because of the overcrowding of a visiting room.

Special visits

Special visits based on unusual circumstances may be approved for immediate family members traveling from other states who visit infrequently. Family members not yet on an inmate’s approved visiting list may be granted a single visit prior to approval, provided they have a photo I.D.

Legal Visits – Attorneys need to call the MSP mail room supervisor at (406) 846-1320, ext. 2258, 2503 or 2228 at least 24 hours in advance to arrange a visit and are expected to arrive on time or the visit may be denied due to institutional time constraints. Attorneys must present proper credentials, including photo identification, to entrance post staff. They are subject to search and all other Department of Corrections’ institutional rules and regulations.

Attorney visits are scheduled Monday through Friday between 8:00 a.m. and 5:00 p.m.

Every effort is made to have attorneys and their clients visit in a room/area that allows privacy. All reasonable precautions are taken to preserve the confidentiality of the attorney-client relationship.

  • Officers visually observe attorney visits, but attorney-client conversations are not recorded or listened to.
  • Attorneys and inmates may exchange written material without it being read.

Visits in the infirmary or hospital – Inmates admitted to the MSP infirmary or a hospital and considered to be in the late stages of the dying process may be allowed to visit with immediate family members or their attorneys at the visiting rooms, the infirmary, or the hospital where the inmate is staying. Arrangements for infirmary and hospital visits must be in writing from the shift commander.

Martz Diagnostic Intake Unit – Inmates are only allowed visits with their attorneys and law enforcement officials.

Inmates with visiting restrictions – Restrictions may be imposed on visiting if it is in the interest of visitor safety, the security of the prison or an inmate’s rehabilitation. Visiting restrictions may result from factors such as disciplinary actions, specific court orders dealing with incarceration, or behavior displayed while in visiting.
