CASS certification

Improperly addressed mail requires the U.S. Postal Service to put more effort into sorting and delivery it; this translates into higher costs for the USPS^®, which are ultimately passed on to retailers via increased postage rates. Address validation and verification reduces the amount of improperly addressed mail; increasing postal efficiency and reducing the manpower required to handle the mail. In the industry, programs that assist in this process are known collectively as CASS certified software.

The USPS^® uses the Coding Accuracy Support System^TM (CASS) to evaluate the accuracy of validation and matching software. It works by checking five-digit ZIP^®, ZIP + 4^® and delivery point codes. Retailers and other organizations, who have certified CASS address validation software, often qualify for lower postage costs and substantial savings over time. Invest in CASS certified software, and you will reap dividends for years to come.
