NCOALink – National Change of Address (standard 48 month)

NCOALink – National Change of Address (standard 48 month) helps keep track of the more than one in seven Americans who move each year as well as checks the overall integrity of mailing addresses.

Over 40 million Americans change their address annually, which creates formidable obstacles in maintaining high-quality mailing lists. NCOALink makes change-of-address information available to mailers to help reduce undeliverable mailpieces before they enter the mailstream.

NCOALink updates individual, family, business and organization address changes going back 48 months by taking advantage of a U.S. Postal Service (USPS) maintained database containing approximately 160 million permanent change-of-address registrations.

To maximize results, as part of NCOALink, each file is checked before processing to look for problems, and the input data is optimized for the best results.

NCOALink is an essential list maintenance tool that increases the deliverability of mail and is necessary for many postal discounts. In addition to move updates, NCOALink incorporates additional services to validate and enhance mailing lists: Address Standardization with CASS certification, Delivery Point Validation (DPV), Locatable Address Conversion System (LACSLink) updates and Gender Coding.
