No Such Street (NSS): Addressed to nonexistent street and correct street not known

No Such Street (NSS)

The return code No Such Street (NSS) indicates that a mail piece was addressed to a nonexistent street and the correct street is not known.

This occurs when the street provided is invalid or doesn’t exist according to the USPS.

Mail can be returned by the USPS and marked with returned mail codes if it is missing NCOA forwarding information or has inaccurate or missing primary or secondary address information. This is why it is important to validate addresses before mailing.

Invalid primary or secondary address information

A common reason for returned mail is invalid primary or secondary address information such as street name, street address or apartment or suite number. TrueNCOA returns status codes from the validation process to help you determine why primary or secondary address information was considered invalid. We provide full definitions of these status codes in our data dictionary.

Missing forwarding information

When someone moves they can submit forwarding information via a change of address form to the USPS. However, if the address is invalid due to incorrect primary or secondary address information the address cannot be matched to a change of address record. TrueNCOA verifies that addresses are valid and deliverable and provides any existing 18 and 48 month address updates for valid address records.
