Finding Someone in Custody in Grand County
A person kept in custody after an arrest in Grand County is held at the county jail, run by the Grand County Sheriff's Office, whichever agency made the arrest.
SearchSystems opened and checked the jail page of the Grand County Sheriff's Office at co.grand.co.us/259/Detentions (page title: Detentions | Grand County, CO), phone 970-725-3343, 80451, Wednesday Males 7:00 p.m. - 9:00 p.m., which answered when SearchSystems opened it on September 23, 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 970-725-3343.
