The USPS has put in place security measures to ensure mailers using DPV and LACSLink processing do not use these applications to generate mailing lists. If the USPS identifies a mailer as repetitively generating False Positive (Seed) violations, the USPS may direct Precisely to invalidate their license. Towards that end, the USPS has created and monitors addresses that generate a False Positive (Seed) violation.
The USPS requires Precisely to report any organization generating a False Positive (Seed) violation during DPV and/or LACSLink processing. If you generate a False Positive result, an error message is generated indicating a False Positive (Seed) violation. VeriMove continues to process your mailing file; however, DPV and/or LACSLink processing are flagged as unavailable. The mailing that generated the False Positive (Seed) violation is identified as not CASS certified.
