SearchSystems opened and checked the jail page of the Montrose County Sheriff's Office at montrosecountysheriffsoffice.com/welcome-to-the-montrose-county-jail (page title: Welcome To The Montrose County Jail | Montrose County Sheriff's Office), phone 970-252-4070, 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 970-252-4070.
