Finding Someone in Custody in Kay County
The county jail, run by the Kay County Sheriff's Office, holds everyone kept in custody after an arrest in Kay County, from every agency.
SearchSystems opened and checked the jail page of the Kay County Sheriff's Office at courthouse.kay.ok.us/176/Kay-County-Sheriffs-Office (page title: Kay County Sheriff's Office | Kay County, OK), phone 580-362-3250, 1101 W Dry Road Newkirk, OK 74647, which answered when SearchSystems opened it on September 28, 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 580-362-3250.
