Let's make your data profitable.

CASS certification is the process of matching your address list to the USPS master list of zip+4 codes, which can change when postal delivery routes change. In addition, CASS provides an extra two digits, called a "delivery point code", that is necessary to create an accurate barcode. In order to take discounts for barcoding, your list must be CASS-certified during the previous six months. This CASS-certified software includes the USPS file of all streets and zip+4 codes, which has around 30 million entries and is updated every two months.
