More information on searching for records by their CensusID can be found [here](/navigating-and-searching/examples-of-typical-searches/find-a-record-if-you-know-the-censusid.md).

Further information about using CensusIDs in referencing or citing records in other databases or in academic publications can be found [here](/using-census-data/how-to-reference-records-in-the-census-database.md).
