Finding Someone in Custody in Denver County
The county jail holds everyone kept in custody after an arrest in Denver County, from every agency.
SearchSystems opened and checked the custody page of the sheriff's office at denvergov.org/inmatesearch (page title: Inmate Search | City and County of Denver), which answered when SearchSystems opened it on September 23, 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.
