Vacant (VAC): House, apartment, office, or building not occupied

Vacant (VAC)

The return code Vacant (VAC) is used when the USPS determines that a House, apartment, office, or building is no longer occupied. This is used only if the mail is addressed “Occupant.”

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.

Missing forwarding information

When someone moves they can submit forwarding information via a change of address form to the USPS. If the resident never submitted this information, the mail will likely be returned. TrueNCOA verifies that addresses are valid and deliverable and provides any 18 and 48 month address updates. We will also indicate if an address has been identified as vacant. This designation indicates that an address may have been previously active, but now has been unoccupied for over 90 days. You can read more about this in our data dictionary.
