Delivery Point Validation (DPV®) is a United States Postal Service® (USPS®) technology that validates the accuracy of address information down to the individual mailing address. By using DPV® to validate addresses, you can reduce undeliverable-as-addressed (UAA) mail, thereby reducing postage costs and other business costs associated with inaccurate address information.
When you validate an address, the address is assigned a DPV code in the DPV field. The DPV codes are:
- Y
- DPV confirmed. Mail can be delivered to the address.
- N
- Mail cannot be delivered to the address.
- S
- The building number was validated but the unit number
could not be confirmed. A building number is the primary
address number for a building. A unit number is a number
of a distinct mailing address within a building such as
an apartment, suite, floor, and so on. For example, in
this address 424 is the building number and 12 is the
unit
number:
424 Washington Blvd. Apt. 12
Oak Park IL 60302
