Finding Someone in Custody in Seminole
A person kept in custody after an arrest in Seminole is held at the county jail, run by the Gaines County Sheriff's Office, whichever agency made the arrest.
SearchSystems opened and checked the jail page of the Gaines County Sheriff's Office at co.gaines.tx.us/page/gaines.sheriff (page title: Gaines County, Texas), phone (432) 758-9871, Monday - Friday 8 a.m. - 5 p.m., which answered when SearchSystems opened it on October 11, 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 (432) 758-9871.
