Delivery Point Validation enables you to verify that an actual address exists … down to the apartment or suite number. When used with CASS certified software that matches the address to a range based ZIP+4 record, delivery point validation determines if the address can be confirmed as a specific delivery point. The United States Postal Service Delivery Point Validation database is updated on a monthly basis.

Using DPV to will virtually guarantee that each direct mail piece will be delivered to the Delivery Point and not “Returned To Sender” because of “No Such Number.”

• DPV actually confirms ZIP+4 coded records actually exist and are a valid Delivery Point, right down to the suite, unit or apartment number.
• DPV uses the USPS-supplied data of more than 151 million records to confirm that an address is actually a deliverable destination.
• Addresses that can not be Delivery Point Confirmed automatically are flagged in your database so you can opt not to mail to these addresses.
