This is a private reference site, not a government office. It cannot confirm whether someone is in custody, release a person, post bond, schedule visits, or obtain official booking records for you. Use the government contact that controls the record or custody system.
Where to Ask for an Inmate or Record
Mercer County does not publish a public official jail roster in the research reviewed for this site, so the correct contact depends on the type of custody or record.

- For someone believed to be at the county jail, start with jail inmate records and the MCCC main phone.
- For booking photos, review jail roster mugshots and use OPRA if an official record is needed.
- For charges filed after booking, use court records after a jail arrest and the NJ Courts portals.
- For a specific facility, use the Mercer County Correction Center or New Jersey State Prison facility pages linked in the footer.
- For a sentenced state prisoner, use the NJDOC offender locator rather than the county jail phone alone.
- For federal or immigration detention, use the BOP inmate locator, U.S. Marshals District of New Jersey contacts, or the ICE Online Detainee Locator System.
