Delivery Sequence File Second Generation (DSF^{2 TM})....

DSF^{2 TM} improves the delivery of your mailings by validating and standardizing the incoming address utilizing the United States Postal Service^® database of approximately 145 million addresses. DSF^{2 TM} is based upon a United States Postal Service^® approved, address only, matching process. Addresses are identified as business versus residential delivery points and provided with Pseudo Delivery Sequence Numbers for walk sequence discounts. We provide a deliverability index to help you decide whether to mail to a specific address. This enables you to improve response rates and lower costs by identifying and not mailing to undeliverable addresses.

Locatable Address Conversion System (LACS)....

LACS enables you to update your mailing lists when addresses have been converted by local authorities from rural to city style address (i.e. Renumbering of houses, usually as a result of a 9-1-1 conversion effort). It improves deliverability and identifies potential duplicates between name and address records that have the original address and those that are already using the new converted address. A National Deliverability Index Report show how your list compares to United States Postal Service^® standards. Processing lists with the 4 million record LACS database has resulted in savings of up to 3% for many direct marketers. The United States Postal Service^® is only required to deliver mail to the old style address for one year after a LACS conversion.

The maximum address hygiene benefits are realized when DSF^{2 TM} processing is done in conjunction with USPS^® FootNotes and LACS.

NCOA^LinkTM Processing is performed by a non-exclusive licensee of the United States Postal Service^®.
