Maintain up-to-date addresses using our change-of-address API Meets NCOALink requirements for mailing discounts
Improve mailing address deliverability by up to 400%

DOTS NCOA Live is a national change-of-address, real-time API, that works directly with the United States Postal Service’s NCOALink 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 NCOALink 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 NCOALink meets the requirements of the USPS Move-Update, helping qualify your mailings for Standard and First-Class Mail discounts.
