How to Find an Inmate at Mercer County Jail

Members of the public can look for an inmate by using the official inmate search link available on this page for the facility’s roster. Jail rosters typically list basic custody information such as the inmate’s name, booking date, charges, bond information when available, and custody status. Records are usually not searchable the moment someone is arrested because booking, identification, and data entry can take several hours. If a person does not appear right away, check again later or contact the facility directly for general custody information. Information may change as charges, court dates, or release status are updated.
