ADDRESS QUALITY
People move. Databases do not move with them unless the record is updated. Recurring NCOALink-based processing helps keep physical-address data current enough to support household identity, geographic qualification, and approved direct mail with greater confidence.
Scale Is Easy to Claim Accuracy Has to Be Maintained
WHEN PEOPLE MOVE
An outdated address does more than waste a mailpiece. It can place a household in the wrong geography, weaken identity resolution, create duplicate profiles, and attach marketing activity to a location that no longer belongs to the person.
When address data supports audience building, geographic qualification, household recognition, or direct mail, freshness becomes part of the marketing decision.
NCOA AND NCOALINK IN PLAIN ENGLISH
NCOALink is a USPS product built from qualifying permanent change-of-address filings.
Licensed processors compare eligible records against that data. When a name and address meet the applicable match requirements, the record may be updated before mailing or related address-quality use.
OFFICIAL MOVE DATA
The underlying source is based on qualifying permanent change-of-address requests filed with the U.S. Postal Service.
LICENSED PROCESSING
USPS makes NCOALink data available to licensed service providers under specific security and use requirements.
ADDRESS CORRECTION
A qualifying match may provide a newer address or indicate that a move occurred, depending on the service and available data window.
ADDRESS REFRESH
Approximately every 30 days through NCOALink-based verification processes.
APPROXIMATELY EVERY 30 DAYS
Our underlying profile data is refreshed on an approximately 30-day cycle using NCOALink-based address verification through licensed processing. That cadence helps maintain physical-address and household context as people move.
Address quality supports more accurate geographic qualification, household recognition, approved direct-mail activation, suppression, and cross-checking of other profile information.
Accuracy Is Maintained Not Assumed
WHAT NCOA DOES AND DOES NOT PROVE
A person must file a qualifying change-of-address request and the record must meet the match requirements.
Email, phone, employer, job title, and other attributes require separate validation.
A current address says where a person may be reached. Behavior and business fit determine whether the record represents an opportunity.
Address quality must be refreshed because the underlying population continues to change.
Combined with identity verification, UID2-compatible activation where supported, behavioral intelligence, and your qualification rules, current address data helps the system reach the right household in the right geography through the right approved channel.
