Finding Someone in Custody in Yates County
A person kept in custody after an arrest in Yates County is held at the county jail, run by the Yates County Sheriff's Office, whichever agency made the arrest.
SearchSystems opened and checked the jail page of the Yates County Sheriff's Office at yatescountyny.gov/quicklinks.aspx?CID=32 (page title: Quick Links, Sheriff), phone 315-536-5100, 417 Liberty Street, Penn Yan, NY 14527, which answered when SearchSystems opened it on October 2, 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 315-536-5100.
