Benton County maintains a public jail roster website where you can search current inmates by name. The roster is authorized under RCW 70.48.100, which requires county jails to keep a public jail register. To search the current roster or contact the jail about an inmate, call the Benton County Corrections Department at 509-783-1451. The jail roster search is available at the county's website.

The Benton County jail roster search page provides access to current inmate data including name, booking date, charges, and custody location within the facility.

The jail roster shows each inmate's Case File Number, name, book date, location within the facility, projected release date, and charges. Data is updated regularly. If you do not find someone in the current roster, they may have been released or transferred. For historical booking data, you would need to submit a formal public records request to the Corrections Department or the Sheriff's Office.

Note: The jail roster reflects current custody and is not a complete arrest history database. Past arrests that did not result in current holds will not appear in the live roster search.

Requesting Benton County Arrest Records

For statewide criminal history searches, use the WATCH portal run by the Washington State Patrol. WATCH covers conviction records across the state and may include Benton County cases that went to conviction. There is a small fee for each search. The WSP Criminal History program handles both public inquiries and agency-level requests for more complete criminal history information.

The Attorney General publishes a guide on obtaining records in Washington that explains requestor rights and what agencies must provide. The MRSC guide on arrest records covers what is public versus restricted, which is helpful before submitting your request.
