Mailing lists? Sharpened. Mailings? Targeted. Postal Discounts? Maximized. The DSF2 file contains every USPS® deliverable address in the U.S., which adds up to over 165 million records. DSF2 sorts mail into walk sequence order. This means the mail is sorted for the mail carrier to optimize delivery– saving the Postal Service™ time and qualifying you for postal discounts such as Enhanced Carrier Route (ECR), Basic, High Density, or Saturation. DSF2 is available through our Service Bureau with fast turnarounds. It also identifies if delivery is to a curb mailbox, door slot, or commercial mail receiving agency (CRMA).
The first step is the processing of your mailing list through CASS™; the USPS certification process for ZIP + 4® matching software. This applies ZIP + 4 codes, carrier route codes, and delivery point; standardizes addresses, and corrects/verifies ZIP® codes. Next, your address information is matched to the DSF2 database. DSF2 uses individual delivery points to match address information while ZIP + 4 processing matches addresses in ranges.
DSF2 processing will return a pseudo code to sort your files and will then update your list(s) by identifying known addresses and specific address attributes: If the address is vacant, residential, business, or seasonal. Then, it returns a flag to designate each record matched. It also identifies whether a ZIP + 4 address is currently represented in the USPS delivery sequence file as a known address record. DSF2 includes DPV®, LACSLink®, and SuiteLink® processing.
