Delivery Sequence File Second Generation Vacant Indicator

Delivery Sequence File Second Generation Vacant Indicator

Output port that indicates whether an address is inactive. The USPS may consider an address inactive if it is unoccupied for 90 days.
The USPS provides the Delivery Sequence File (DSF) system to help organizations to identify deliverable addresses. The DSF is a computerized file that contains all delivery point addresses served by the USPS, with the exception of general delivery addresses. DSF2 is the second generation of this system.
Address validation validates an address against the DSF file if the address contains a valid Delivery Point Code.
An address is considered "general delivery" if the addressee cannot receive mail at a physical mailbox. General delivery addressees can collect mail at a USPS post office.

Delivery Sequence File Second Generation Vacant Indicator Usage

Select Delivery Sequence File Second Generation Vacant Indicator to identify addresses that the USPS considers undeliverable because the DSF2 file indicates that the address is unoccupied.
