Finding Someone in Custody in Johnstown
A person kept in custody after an arrest in Johnstown is held at the county jail, run by the Fulton County Sheriff's Office, whichever agency made the arrest.
SearchSystems opened and checked the jail page of the Fulton County Sheriff's Office at fultoncountyny.gov/sheriffs-office (page title: Sheriff's Office | FULTON COUNTY), phone (518) 736-2100, 2712 State Highway 29 PO Box 20 Johnstown, NY 12095, 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 (518) 736-2100.
