Postal Cleansing & Discounts

All addresses (with the exception of international addresses) in the SSS database undergo an address cleansing process in accordance with the U.S. Postal Service Coding Accuracy Support System (CASS) and are subject to address correction using the National Change of Address (NCOA) database. Overall, 94 percent of SSS addresses are updated using these methods. All names included in your output are considered deliverable, even if some cannot be discounted. Discuss your marketing and direct mail strategies with your local post office to receive the maximum benefit of available postal discounts.
