Delivery Point Validation — a USPS dataset that confirms whether a specific address (down to the suite or apartment level) is a valid, active delivery point that receives mail.
DPV (Delivery Point Validation) goes beyond basic address standardization by checking whether the specific combination of primary address and secondary unit is an actual delivery point in the USPS system. While CASS processing can assign a valid ZIP+4 to a street address, DPV confirms that the individual apartment, suite, or box number exists.
DPV returns one of four results: confirmed (exact match), missing secondary (valid building but no unit specified), not confirmed (address not in USPS database), or vacant (previously active address now vacant). The DPV database is updated monthly by the USPS.
DPV is used by mailers to reduce undeliverable-as-addressed (UAA) mail, by e-commerce platforms to validate shipping addresses at checkout, and by financial institutions for identity verification and fraud prevention.
