Finding Someone in Custody in Rockland County
The county jail, run by the Rockland County Sheriff's Office, holds everyone kept in custody after an arrest in Rockland County, from every agency.
SearchSystems opened and checked the jail page of the Rockland County Sheriff's Office at rocklandcountyny.gov/departments/sheriff (page title: The Rockland County Sheriff's Office | Rockland County, NY), phone 845-638-5400, 55 New Hempstead Rd. New City, NY 10956, 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 845-638-5400.
