Finding Someone in Custody in Jerome County
A person kept in custody after an arrest in Jerome County is held at the county jail, run by the Jerome County Sheriff's Office, whichever agency made the arrest.
SearchSystems opened and checked the jail page of the Jerome County Sheriff's Office at jeromecountyid.us/194/Jerome-County-Jail (page title: Jerome County Jail | Jerome County, ID), phone 866-516-0115, 2151 S Tiger Drive Jerome, ID 83338, which answered when SearchSystems opened it on September 24, 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 866-516-0115.
