Finding Someone in Custody in Gulfport
The county jail, run by the Harrison County Sheriff's Office, holds everyone kept in custody after an arrest in Gulfport, from every agency.
SearchSystems opened and checked the custody page of the Harrison County Sheriff's Office at harrisoncountysheriff.com/inmate-search (page title: Inmate-search | Harrison County Sheriff's Office), phone 228-865-7060, which answered when SearchSystems opened it on September 24, 2026.
That page is the place to look for someone booked recently. A person cited and released at the scene, or held only a few hours by a city department, will not be on it.
