National Change of Address


NCOA Quick Guide

National Change of Address makes USPS Address Updates (NCOA) information available to mailers, service bureaus, list owners,and database admins to help update addresses and reduce undeliverable mailpieces.



Steps that take place when your data begins NCOA processing:

  1. Clean data is good data, which is why your input addresses will undergo our robust dual-engine USPS address standardization including data hygiene and appending the ZIP+4 code
    • Note: You do not necessarily need to have Zip4 data in your input file; our processing will even fix that!

  2. Once your input addresses have been standardized and the ZIP+4 code applied, your input names & address are then matched against the NCOA masterfile, which includes all the latest USPS address updates and contains approximately 160 million records & 48 months of permanent address changes.

  3. If a match is made using the old address information along with the input name, then the new address is appended to your data!
    • Note: Your original data is never overwritten; in fact, our return files include all original data intact followed by appended NCOA columns.
NCOA is a comprehensive program that assists in identifying changes of address and keeping mailing data current & up-to-date. Recommended NCOA use is every 95 days according to USPS.

The USPS masterfile is typically updated on a weekly basis by the USPS. NCOAsource improves mail deliverability by checking the last 4 years' for individual, family, and business moves and providing mailers with current, standardized 5-digit ZIP Codes, 4-digit add-on codes, and 3-digit delivery point addresses.
