DSF - Delivery Sequence File
DSF processing provides a number of benefits for mailers. The process includes DPV®(Delivery Point Validation) which indicates whether a ZIP + 4® coded address is currently represented in the USPS® delivery file and is deliverable. DSF is one of the approved methods for sequencing mail pieces into walk-sequence. This process can identify characteristics that can influence marketing strategies by distinguishing between residential and business addresses, and identifying seasonal addresses, vacant locations, CMRA (Commercial Mail Receiving Agencies), “drops” and other address delivery information.

Walk Sequence DSF is required to qualify for walk sequence automation discounts, assigning walk sequence numbers to every record in your database and arranging the records in sequence. All the documentation required to qualify for walk sequence rates is also provided.
