NCOALink® (NCOA / National Change-of-Address)

Increase Deliverability Quotient with Change-of-Address Service

Over 43 million Americans move each year, which contributes to the declining accuracy of your mailing lists and a major cause of undeliverable-as-addressed (UAA) mail. National Change of Address processing (NCOA) helps reduce UAA mail by identifying and updating the addresses of people and businesses that have moved.

As a NCOALink Full Service Provider licensee of the USPS®, Melissa Data will match your list against the full USPS NCOALink® dataset of approximately 160 million records, which includes all permanent change-of-address records filed with the USPS over the last 48 months, unlike other providers with a limited NCOALink, that only have access to change-of-address records filed in the last 18 months (about 60 million records). Only a Full Service Provider like Melissa Data can identify and update the most change-of-address records in your list.
