What is the Coding Accuracy Support System Certification?

The Coding Accuracy Support System (CASS) is a program developed by the USPS to evaluate and certify software products that correct and standardize mailing addresses. The certification helps ensure that mail is delivered efficiently by reducing errors and undeliverable addresses.

CASS-certified software is tested against a series of criteria, including:

• Correcting misspelled street names and city names

• Adding missing address elements like ZIP+4 codes

• Validating addresses against the USPS database

• Improving mail delivery speed and reducing postal costs

For organizations involved in mass mailing, using CASS-certified products is often mandatory to qualify for postal discounts and to maintain mailing accuracy.
