Maine State Prison Inmate Search. Confirm Someone Is in MDOC Custody

Yes. MDOC's Adult Resident/Adult Community Corrections Client Search covers everyone in MDOC custody statewide, including residents at Maine State Prison. It's free, available 24/7, and updated daily.

If the arrest was recent and no MDOC sentence has been handed down yet, they're likely still in county custody, since MDOC doesn't operate jails. Check with the county where the arrest or court case is happening instead. If they've already been released or transferred to federal custody, the search will reflect that instead of showing them at Maine State Prison.

No, this tool only shows current custody and supervision status. If you need someone's full criminal history, request it separately through MDOC's Public Criminal History Request service.

It's an estimate based on the resident earning every possible day of good time credit, not a confirmed release date. For the most current release information, ask the resident directly.

Yes. The same tool tracks adult community corrections clients too, covering probation, sex offender supervised release, supervised community confinement, and parole.

They remain under MDOC's jurisdiction but may be physically housed at a county jail, another state, or a federal facility. Call (207) 273-5300 to confirm exactly where they're located before you travel.

You'll still need to apply as an approved visitor and schedule a visit separately, and set up MDOC's Money Deposit Service to send funds. See the visitation and send-money guides for the full process.
