Finding Someone in Custody in Buffalo County
A person kept in custody after an arrest in Buffalo County is held at the county jail, run by the Buffalo County Sheriff's Office, whichever agency made the arrest.
SearchSystems opened and checked the jail page of the Buffalo County Sheriff's Office at buffalocountywi.gov/departments/sheriff/jail (page title: Huber Intake | Buffalo County Resource), phone (608) 685-4433, 407 S. 2nd St Alma, WI 54610, which answered when SearchSystems opened it on September 23, 2026.
That page is the office's jail information page rather than a roster, so a search for a particular person goes through the office at (608) 685-4433.
