The NCOALink® Product (which replaced the NCOA National Change of Address system in 2004) 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®.
Developed with secure data store technology to increase security of postal customer data and protect the privacy of this information, the NCOALink Product enables mailers to process mailing lists and update lists with new addresses prior to mailing. The NCOALink Product can be integrated into mailers’ in-house computer systems to provide services or use internally.
The use of the NCOALink Product is only available through licenses from the USPS. There are three types of NCOA license types available from the USPS:
- Full Service Licensees receive 48 months of change of address data.
- Limited Service Licensees receive 18 months of change of address data.
- End User Licensees receive 18 months of change of address data, but are only allowed to process lists that are owned by the licensee.
