CASS Certification
With The PLD Group, you can be assured your files are certified by the USPS as meeting all requirements of the Coding Accuracy Support System (CASS). CASS is the process that assures accurate carrier route, 5-Digit, ZIP+4 Codes, and Delivery Point Barcodes are placed on mail pieces by address-matching software. To receive automation-based discount rates, the USPS requires that mailings be produced from address lists that have been matched to CASS-certified software within the last 3 months.
Our program cleans codes and standardizes the address information, according to USPS standards, in a single pass of the data file.
CASS Certification is a mandatory requirement for automation discounts; this process standardizes an address using standard abbreviations, correct spelling and proper format. Once certified, the zip code is extended to Zip+4 pointing that address to a known block range. Did you know? An address could certify and still not be deliverable … for example Main St has addresses from 101 to 199 as the designated USPS block. 123 Main St will then barcode even though there is no such building or house with a 123 Main St address
