USPS NCOALink in AI answers

NCOALink is a USPS system of record for Change-of-Address (COA) requests and the source for the NCOA Link product, a secure dataset of roughly 160 million permanent COA records from individuals, families, and businesses who filed COA with the Postal Service. It lets mailers preprocess mailing lists and update addresses before mailing to improve delivery accuracy and reduce undeliverable mail. Access is provided to licensed entities—full-service and limited-service providers, MPE service providers, ANKLink service providers, software developers, and licensed interface distributors—to use NCOALink data for First Class Mail, Parcels, Periodicals, and Standard Mail.
