Why Data Hygiene Is Essential
At Mailings Unlimited, we understand that the foundation of successful Direct Mail marketing lies in maintaining clean, accurate, and current mailing lists. With people frequently relocating—due to career moves, education, family, or lifestyle changes—address data can quickly become outdated, leading to wasted resources and missed connections.
This is where National Change of Address (NCOA) processing plays a vital role. It ensures your address lists remain up to date, improving deliverability, reducing waste, and supporting effective customer communication.

What Is NCOA and How Does It Work?
The NCOA database, maintained by the U.S. Postal Service (USPS), contains updated address information for individuals and businesses who have filed change-of-address notices within the past 18 months. When someone moves and informs USPS, the new address is recorded and added to the NCOA database.
By comparing your mailing list against this database, you can correct outdated entries before mail is sent—ensuring your communications reach the right recipients.

The Costs of Neglecting Address Updates
Ignoring address accuracy can have serious financial and operational consequences:
• Wasted spending on printing, postage, and processing undeliverable mail
• Lost marketing opportunities when messages don’t reach their audience
• Damaged brand credibility and strained customer relationships
• Compliance issues in regulated industries where up-to-date contact records are mandatory
Key Benefits of NCOA Processing
Integrating NCOA processing into your mailing workflow brings several advantages:
• Improved deliverability: Mail reaches the right people, enhancing the effectiveness of your campaigns.
• Higher customer satisfaction: Accurate mailings ensure timely and relevant communications.
• Reduced UAA (Undeliverable-As-Addressed) mail: Less returned mail means fewer manual fixes and better efficiency.
• Lower mailing costs: Avoid spending on mail destined for the wrong address.
• USPS postage discounts: Businesses using NCOA processing can qualify for significant discounts, especially on high-volume campaigns
Ensuring Compliance
In industries like healthcare, finance, and government, maintaining accurate addresses isn’t optional—it’s a compliance requirement. NCOA processing supports adherence to regulations and minimizes audit risks. Additionally, USPS mandates that lists be NCOA-processed at least once every 95 days to maintain eligibility for discounted mailing rates.
