Missouri DOC offender search allows searches by DOC number or name. Missouri has 114 county jails - one of the highest county counts of any state. The state has made significant investments in mental health treatment within corrections.
The official inmate search is available at web.mo.gov/doc/offSearchWeb/input.do. USP Leavenworth (KS, near Missouri border) and FCI Greenville (IL) house some Missouri federal inmates.

Frequently Asked Questions About Missouri Prisons
What is the old Missouri State Penitentiary?
The original Missouri State Penitentiary in Jefferson City opened in 1836 and operated as a functioning prison for 168 years before closing in 2004 - one of the longest-operating state prisons in American history. Built of stone and considered one of the most brutal prisons in the country during much of its history, it held infamous criminals and was the subject of lawsuits and exposés over many decades. After closing, it became one of Missouri's most popular tourist attractions - offering public tours, ghost tours, escape rooms, murder mystery dinners, and special events. It is worth visiting if you're in the Jefferson City area. Your current MDOC inmate is housed at the newer Jefferson City Correctional Center nearby, which is a separate modern facility not open to the public.
What is Potosi Correctional Center?
Potosi Correctional Center is Missouri's maximum-security death row facility, in Mineral Point in Washington County in the Ozarks, about 80 miles south of St. Louis. It houses Missouri's most serious long-term offenders and those condemned to death. Missouri has carried out executions at Potosi. Visiting there is more restrictive than at Missouri's medium-security facilities - contact Potosi directly at 573-438-6000 for specific visiting procedures for your inmate's classification. The remote Ozarks location can make travel difficult for families in Kansas City, St. Louis, or northern Missouri. Programming and visiting access are more limited at Potosi than at other Missouri DOC facilities, as is typical for death row operations.
Does Missouri have free prison phone calls?
No - Missouri has not eliminated phone call fees for state inmates. Securus Technologies holds the Missouri DOC contract. The FCC's April 2026 rate caps reduced per-minute rates at state and federal facilities, but calls in Missouri are still charged per minute. Missouri county jail phone rates vary by county and provider. Missouri's 114 counties and wide geographic spread mean many families face real travel challenges for visits, making phone contact especially important as a primary means of regular connection. If phone costs are a barrier, written mail, JPay electronic messaging, and InmateAid's Letters & Photos service are cost-effective alternatives.
What is the DOC number in Missouri?
The DOC number is the unique identification number assigned by the Missouri Department of Corrections to every person sentenced to Missouri state prison. It must appear on the outside of every envelope you mail to a Missouri DOC facility - mail without it is delayed or returned. Find your inmate's DOC number through the Missouri DOC Offender Search at web.mo.gov/doc, or ask your inmate directly. Keep it somewhere accessible - you'll use it for every piece of mail, every JPay deposit, and any time you contact facility staff or Missouri DOC's central office.
How do I find someone in a Missouri county jail?
Missouri has 114 counties plus the independent city of St. Louis - more county-level jurisdictions than almost any other state. If your person was recently arrested, they're most likely in the county jail where the arrest occurred. Contact the county sheriff's office directly - most Missouri counties have online inmate rosters. Be aware that St. Louis City and St. Louis County are separate jurisdictions: someone arrested in St. Louis City goes to the City Justice Center, not to the Clayton facility that serves the county. The Missouri DOC Offender Search covers only sentenced state inmates. If your person is awaiting trial or serving a misdemeanor sentence, they won't appear there.
What is the Missouri Reentry Process?
The Missouri Reentry Process (MRP) is Missouri DOC's structured approach to planning an inmate's transition back to the community, typically beginning 12 - 18 months before a projected release date. MRP involves case managers, community partners, and the inmate working together on a release plan covering housing, employment, treatment needs, family support, and supervision requirements. For families, MRP is the most structured opportunity to engage with DOC about reentry planning - if your family member is in MRP, you may be contacted as part of the process, or you can reach out to their case manager to discuss your role in their release plan. Reentry planning that includes active family support has been shown to significantly improve outcomes.
