NCOA might sound like another vague initialism, but it's an important one. It stands for National Change of Address ? a secure database that holds 160 million permanent change-of-address records. NCOA is a product of the United States Postal Service, which is better known by its own initialism, USPS.

CASS (Coding Accuracy Support System) and NCOA (National Change of Address) are two methods of address data verification. CASS tells you if an address can receive mail. NCOA provides the current address for your recipient assuming they have filed a USPS change of address within the last 48 months.

Definition: CASS? address standardization is the process of standardizing addresses so that they follow the USPS® Coding Accuracy Support System (CASS?) requirements. CASS? certification is based on accuracy in ZIP codes?, ZIP +4® codes, and delivery point codes.

What is CASS? Coding Accuracy Support System (CASS) is a certification system from the United States Postal Service (USPS) for address validation. A CASS-certified address validation service will standardize your mailing list, update outdated addresses, and verify that addresses are valid and complete.

To become CASS-certified, vendors must pass with a minimum score of 98.5 percent for ZIP + 4, carrier route, Five-Digit ZIP, and LACSLink, and 100 percent for delivery point coding, eLOT, DPV or DSF2, RDI, and Perfect Address.

CASS(Coding Accuracy Support System) Certification is program that was developed by the USPS to test the accuracy of address-matching software and improve the accuracy of postal coding, such as ZIP+4 Code®, carrier route and 5-digit ZIP Code coding.

Can You Opt Out of NCOA? We are required to use NCOA for all Standard and First Class mail with furnished lists unless the mailing address of each piece includes either "OR CURRENT RESIDENT" or "TO OUR FRIENDS AT" or similar. Acquired lists have already been run through NCOA by the list owner or broker.

If a person or company files a change of address with the United States Postal Service® the information is maintained on the NCOALinkTM database for 48 months.

The CASS system gives the USPS a way to evaluate and measure how accurate the results of that private party's software processes are. This means that an address processed by a standardizer or address validator that is using CASS-certified software is more reliable than an address that is not.
