Address verification with CASS database

Address validation reduces the amount of improperly addressed mail your organization sends; correctly addressed mail helps to increase postal efficiency and reduces the manpower necessary to handle the mail and packages. Programs that assist in the process of guaranteeing addresses are accurate by USPS Standards are known collectively as CASS™-certified software. CASS™-certified software will increase your ability to send mail to the right people and reduce the amount of undelivered mail.  

Our CASS™ certification is based on accuracy in ZIP codes, ZIP +4® codes, and delivery point codes. CASS™ refers specifically to the verification status of a contact list or address database. By adopting a CASS™-certified software and having a certified database, your organization can qualify to receive discounts on shipping and bulk mailing costs. In addition, companies will benefit from having a verified and standardized contact database, which can increase both efficiency and accuracy in bulk mailings. 

Once data has been processed through a CASS™-certified product, a CASS™ Summary Report can be generated. This report contains information about the condition of the original addresses and how the addresses have changed after cleaning.
