Coding Accuracy Support System (CASS) Certification is the verification of a list of addresses that has been matched against the USPS Address Matching System. CASS improves the accuracy of matching to multiple delivery point codes, including:
- ZIP + 4 Codes
- 5 digit ZIP Codes
- Carrier Route Codes
All mailing lists are required to undergo address verification every six months to ensure they meet the standards of the United States Postal Service.
CASS Certification improves delivery rates and determines qualification for bulk postal mail discounts. CASS Certification only applies to the ZIP code portion of the postal address.
