DPV is a USPS validation process that confirms the existence of a specific address
(down to the apartment or suite number) and whether or not it can be delivered to.
DPV checks for one of the following scenarios:
Correcting potential addressing issues can reduce the amount of undeliverable-as-addressed
(UAA) pieces, which in turn will result in more efficient mail processing and delivery.
- The address has the correct primary and secondary data
- The address has the correct primary but not secondary data
- The address cannot be validated
CDYNE’s PAV API returns the following result codes for DPV validation:
- 10 Input address is not found
- 100 Input address is DPV confirmed for all components
- 101 Input address is found, but not DPV confirmed
- 102 Input address primary number is DPV confirmed - Secondary number is present
but not DPV confirmed
- 103 Input address primary number is DPV confirmed - Secondary number is missing
In addition to the result codes, CDYNE PAV will return USPS mailing industry information that can be useful for interacting with address verification at point of entry. A detailed chart of return codes, footnotes, and suggested interactions may be found here.
