What is a False-Positive?

To prevent the generation of address lists, the DPV and LACSLink databases include false-positive records. False-positive records are artificially manufactured addresses that reside in a false-positive table. For each negative response that occurs in a DPV or LACSLink query, a query is made to the false-positive table. A match to this table (called a false-positive match) disables your DPV or LACSLink key. In batch processing the job that contains the violation will complete successfully but you will not be able to run any subsequent jobs that use DPV or LACSLink until you report the violation and obtain a key to reactivate DPV or LACSLink.

Note: The term "seed record violation" is also used to refer to encountering false positive records. The two terms mean the same thing.
