How to Find an Inmate at Redgranite Correctional Institution

Visiting, Mail and Phone Calls
Visiting days, visitor approval, dress rules and the mailing format for letters are set by the Wisconsin Department of Corrections and can change at short notice. Read the official facility page and call ahead before you travel.
