DSF Processing

Identify Deliverable Addresses and Specific Address Attributes

DSF2 processing is available through USPS® DSF2 licensees. The DSF2 file contains over 165 million U.S. delivery points. The database was created by compiling the delivery information from all USPS mail carriers. The mail carriers provide the delivery point address; the type of delivery (business vs. residential); seasonal addresses; the type of mail receptacle (mailbox on curb, mail slot in door, etc.), and the sequence the mail is delivered in. DSF2 processing provides valuable information such as Commercial Mail Receiving Agency (CMRA) identification and vacant address identification.

Please note:
DSF2 Agreement must be completed for processing.
