ACS CASS It! provides your church, school, or organization with the tools to CASS™ (Coding Accuracy Support System) certify your mailing addresses and meet United States Postal Service® (USPS) requirements for address verification.
CASS certification ensures that the addresses in your database are valid. This helps your mailing's recipients receive your organization's mailings faster and prevents you from receiving numerous returned mail pieces. In addition, CASS certification qualifies your organization for postal discounts and automation rates. You can also update your CASS certification each time you send a mailing, ensuring that addresses are correct for individuals recently added to your database.
CASS improves the accuracy of carrier route, 5-digit ZIP, ZIP+4, and delivery point codes that display on mail pieces. In order to receive automation rates, addresses must be matched and coded to current USPS directories using CASS certified software. In addition, CASS It features a solution to the USPS Move Update requirement. National Change of Address (NCOA) processing is available within the CASS It module and keeps your addresses up-to-date while meeting USPS requirements for bulk mailings.
