Finding Someone in Custody in Farmington
A person kept in custody after an arrest in Farmington is held at the county jail, run by the Washington County Sheriff's Office, whichever agency made the arrest.
SearchSystems opened and checked the jail page of the Washington County Sheriff's Office at washingtoncountyar.gov/government/departments-f-z/sheriff (page title: Sheriff | Washington County, AR), phone (479) 444-5700, 1155 W. Clydesdale Drive Fayetteville, AR 72701, Monday - Friday 8:00am - 4:30pm, which answered when SearchSystems opened it on October 4, 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 (479) 444-5700.
