When Validating an address on the USPS Official Website, an Existent Address or Non- Existent Address will be returned based on the information submitted.
Existent Address is returned when the USPS provides both the main locality postal code as well as the +4 area designed postal code.
Double check if the address is deliverable by clicking on the arrow to the right of the returned address. Check the DPV Confirmation Indicator for “Y” . The “Y” indicates that the postal service considers the address as deliverable
A Non-Existent Address is returned when the zip code is missing the 4+ postal code designation. When this is missing, it is likely that the address does not exist.
Double check if the address is deliverable by clicking on the arrow tab to the right of the returned address. Check the DPV Confirmation Indicator for an “N”. The letter “N” indicates that the postal service does not consider the address as deliverable.
When an Address is not returned, USPS indicates the address is Non-Existent by providing an error. Make sure to always double check for misspellings and matching street type. The USPS does not always autocorrect incorrect address information and may present a False-Negative.
