What is NCOALink?
The NCOALink Product matches names and addresses on your mailing list to changes of address filed with the USPSĀ® by relocating postal customers. When the name and address information on your mailing list matches the name and address information on the NCOALink file, a new address will be returned. NCOALink Full Service contains 48 months of permanent address changes and Limited Service contains 18 months of changes that are both updated weekly. The file is maintained by the U.S. Postal ServiceĀ® and is licensed to vendors such as Lorton Data.
