The USPS® offers an 18-month and 48-month option for NCOA processing and knowing which version your provider runs can have a large impact on your marketing success.
NCOA's Impact on Your Marketing ROI
Each year, 25-30 million Americans relocate, leaving marketing databases filled with outdated addresses. This creates a significant challenge for marketing managers: approximately 5% of all direct mail fails to reach its intended recipients due to incorrect addresses. The result? Diminished campaign performance, reduced response rates, and wasted marketing budgets.
The solution lies in NCOALink®, USPS®’s secure database containing 160 million change-of-address records from individuals, families, and businesses. This service identifies and corrects address errors before your campaigns launch, ensuring your marketing messages reach your target audience.
Understanding NCOALink® Full Service 48 Month vs. Limited Service 18 Month
USPS® awarded Anchor its first NCOALink® Full-Service Provider license over three decades ago. Today, there are only 15 Full-Service Providers in the US. This distinction matters significantly for your campaign outcomes. Full-Service Providers access 48 months of current address data, while Limited-Service Providers work with only 18 months of information.
The extended period delivers measurably better results. In fact, 43% of address changes occur between months 19-48 — data that Limited-Service providers miss entirely!

Our client, a marketing agency with over 35 years of experience, has worked with print vendors without questioning their NCOA service. After learning that the 48-month versus 18-month service can capture 43% more of new movers, they now specifically request Full-Service NCOA for all campaigns.
Our experience has shown that Full Service 48-Month processing identifies significant moves beyond the 18-Month Limited license.
When utilizing 18-Month limited licenses, moves from 19 months and older are left as addressed, resulting in significant missed opportunity to reach the intended audience and wasted marketing dollars.
