DOTS NCOA Live is a national change-of-address, real-time API, that works directly with the United States Postal Service’s NCOA^Link service to ensure your addresses are kept up-to-date, cleansed and standardized. NCOA Live validates and corrects both residential and business addresses using USPS CASS-certified address correction services before matching the addresses and names against the NCOA^Link database of over 40 million annual moves.

For larger volume requests, NCOA Live’s real-time, RESTful API supports up to 500 records in a single request and multiple requests running in parallel. Our application engineers are available for a complimentary consultation and can provide sample code to help set up this approach.

In addition to maintaining accurate mailing addresses, the use of NCOA^Link meets the requirements of the USPS Move-Update, helping qualify your mailings for Standard and First-Class Mail discounts.
