This is a private reference site, not a government office. We cannot confirm whether someone is in custody, release a person, post bond, approve visits, or pull official booking records. Use the official Knox County and Ohio contacts below for those actions.
Knox County Jail Contacts
The Knox County Sheriff's Office operates the Knox County Jail and maintains the official jail roster and jail records channels. For urgent custody questions, use the jail line. For public-record requests, use the records contact published by the sheriff's office. The county public-records policy says requests are handled during the regular business hours of the department, and the research did not identify a separate public counter schedule for sheriff records.

Use the record type to choose the right path before calling or sending a request.
- For a person held in the county jail, start with jail inmate records and then call the Knox County Jail if the PDF roster is stale or unclear.
- For booking photos on the county roster, use jail roster mugshots and then ask sheriff records if a public-record request is needed.
- For charges filed after booking, use court records after a jail arrest because the court case can differ from the booking charge.
- For facility details, use the Knox County Jail page listed in the footer.
- For an Ohio sentenced prisoner, use the Ohio Department of Rehabilitation and Correction Offender Search instead of the county jail roster.
- For a federal or immigration detainee, use the Bureau of Prisons locator or the ICE Online Detainee Locator System.
