Princeton, NJ Public Records
Princeton is an incorporated municipality in Mercer County, New Jersey, with an estimated population of 31,445 (U.S. Census Bureau, July 2024 estimate) and 17.9 square miles of land. That is up about 756 residents since the 2020 Census base.
🏢 Princeton Local Government Office
Princeton's own municipality government keeps its local records: council or board meeting minutes, local ordinances and resolutions, local permits and licenses, and its own budget and contracts. Requests for those records go to the clerk under New Jersey's Open Public Records Act (OPRA). In New Jersey, every municipality has a local registrar who issues certified copies of birth, marriage and death records for events in that municipality, and marriage licenses are applied for there, so the municipal office is the first stop for vital records.
