CASS™ certification of the United States Postal Service (USPS) for Software Library

The USPS offers an official certification process (CASS) for address validation software. Certification is an absolute necessity if you plan to post bulk mail at discounted rates within the US.

USPS defined new CASS Certification requirements for the current CASS Cycle M including Suite^Link. AddressDoctor achieved CASS certification for Cycle M for its software library in March 2010. The complex USPS requirements for DPV (Delivery Point Validation), LACSLink (Locatable Address Conversion System) and Suite^Link were mastered successfully. All are necessary to achieve certification for the current CASS certification Cycle M.

The USPS states that DPV, LACSLink and Suite^Link data must remain within the US. Consequentially, address cleaning software using DPV, LACSLink and Suite^Link data is not allowed to circulate outside of the US.

Software vendors located in the US can integrate the AddressDoctor CASS certifiable components into their software and have their product certified by the USPS. Customers outside the US can still use AddressDoctor libraries with the US reference database without DPV, LACSLink and Suite^Link data. ZIP+4 codes will then be assigned based on the previous logic.
