The United States Postal Service has now made it mandatory that anyone seeking to receive discounted automated rates must have their names processed through Delivery Point Validation or DPV software. The goal of this software is to reduce the amount of Undeliverable-As-Addressed or UAA mail that is processed by the USPS.

One of the main advantages of the DPV service is that it pinpoints if a record is a valid USPS delivery destination. DPV’s other half, the CASS certification service, can only tell you if the address falls within a range. For example, if you have 123 Main Street, CASS can confirm that it falls within a range of 1-200 Main Street but doesn’t confirm that it’s a valid USPS delivery destination.

But Delivery Point Validation does.

Ultimately, DPV is important because the more we can do to help make the post office more efficient, the better off all direct mail marketers will be.
