The Coding Accuracy Support System (CASS) was designed by the United States Parcel Service (USPS) to ensure accuracy and address-matching more quickly and easily. Companies send a lot of mail to their customers and potentials, so they need to make sure that all information is correct and that the address is recognized. Otherwise, they run the risk of sending items that cannot be processed, which can lead to more costs and lower retention of customers.

What It Offers

The Certified Postal Software provides up to 98 percent accuracy for five-digit coding, ZIP+4 coding, carrier routes and more. With five-digit coding, you will be sure that the ZIP code you’ve entered is legitimate and correct so that the item will be delivered to your customer.

Likewise, the ZIP+4 feature will ensure that the added digits of the ZIP code are available and entered correctly, which saves the USPS time when sorting.

Carrier route codes can also be included on the envelopes so that they are presorted directly to the mail carrier who will deliver the piece. This ensures faster delivery and no risk of it being delayed because it was given to the wrong carrier. Plus, you can usually get presort discounts for doing this yourself, which can save you money.

DPV

Delivery Point Coding (DPV) is also available with CASS certified postal software and ensures that the address you’ve entered is valid, including the suite or apartment number. It also proves that it is a physical address and can have mail delivered to it.

LACS

LACS is part of many software options that checks your address against of highway route, rural route or box number addresses that may have been renamed or renumbered because of 911 conversions. Many customers forget and still include the old address, which can be confusing to mail carriers and sorters at the USPS.
