Finding Someone in Custody in Clatsop County
The county jail, run by the Clatsop County Sheriff's Office, holds everyone kept in custody after an arrest in Clatsop County, from every agency.
SearchSystems opened and checked the custody page of the Clatsop County Sheriff's Office at apps.clatsopcounty.gov/jail (page title: Clatsop County Jail Roster), 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.
