DSF^2®

Peachtree Data licenses the DSF² product from the USPS to further enhance and identify addresses in your mailing list as USPS delivery points. Using the DSF² product helps to reduce the amount of undeliverable-as-addressed (UAA) pieces, which in turn will result in more efficient postal mail processing and delivery operations.

Using the DSF² file on your mailing list can provide several benefits:

• Identify if an address has been vacant for more than 90 days
• Identify if an address is at a business or residential location
• Identify records that are seasonally occupied
• Identify records that are located at an educational institution
• Identifies if an address is delivered to a curb-side mailbox or by a door-slot. This information allows for more targeted mailings.
• DSF² processing is one of the approved methods outlined in the Domestic Mail Manual for sequencing mail pieces in walk-sequence. This could allow you to qualify for lower postage rates.

DSF² processing can be provided as a stand-alone service, however we recommend running the DSF² service along with the NCOA^Link service to update your mailing list with change-of-address information in one pass.
