How to Find an Inmate at Grimes Unit
People serving state sentences are listed in the state's offender search, not on county jail rosters. Search by last and first name, or by the state inmate number if you have it; the result shows where the person is held now, which can change after a transfer.
Visiting, Mail and Phone Calls
Visiting days, visitor approval, dress rules and the mailing format for letters are set by the Arkansas Division of Correction and can change at short notice. Read the official facility page and call ahead before you travel.
