Data Processing
With over 40 million Americans changing their mail address each year, maintaining a high-quality deliverable mailing database becomes a formidable task. SouthWest Direct® has invested in the mailing software and technology that can save thousands in returned and undeliverable-as-addressed (UAA) mail. SouthWest Direct employs CASS, LACS, DPV, NCOA, along with other proprietary and third party systems to ensure the integrity and enhance the quality of your mailing data.
CASS (Coding Accuracy Support System)
Improves the accuracy of postal carrier route, five-digit ZIP®, ZIP + 4®, and delivery point bar codes that appear on mail pieces. CASS standardizes the address, checks for delivery range accuracy, adds the correct zip+4 and Carrier Route, and provides error codes for failed addresses.
LACS (Locatable Address Correction Service)
It is a secure dataset of converted addresses that primarily arise from the implementation of a 911 system, which commonly involves changing rural-style addresses to city-style addresses. The LACS Link Product also contains existing city-style addresses that have been renamed or renumbered.
DPV (Delivery Point Validation)
This process takes the CASS certified file and further verifies the specific mailing address. Every valid deliverable address in the United States is maintained in this file. DPV certifies that the addressed mail piece is deliverable to a specific address. Additional error reporting is provided to better resolve address deliverability failures.
NCOA Link™ (National Change Of Address)
It is a secure dataset of approximately 160 million permanent change-of-address (COA) records consisting of the names and addresses of individuals, families, and businesses who have filed a change-of-address with the USPS. This dataset goes back 18 months tracking all registered moves within the United States. Extensive error code reporting provides the mailer with accurate address failure explanations.
