CorrectAddress® Is CASS Certified USPS Software

The CASS™ (Coding Accuracy Support System) improves the accuracy of carrier route, five-digit ZIP®, ZIP+4®, and delivery point codes that appear on mail pieces. CASS is offered to all mailers, service bureaus, and software vendors who want to evaluate their address verification software and improve the quality of their ZIP+4, CRIS, and five-digit coding accuracy. This process is graded by the United States Postal Service®, National Customer Support Center (NCSC), and the results returned to mailers in order to provide useful diagnostics for correcting deficiencies.

CASS enables the Postal Service™ to evaluate the accuracy of address-matching software programs in three areas: (1) ZIP+4 delivery point coding, (2) carrier route coding, and (3) five-digit coding. CASS allows vendors/mailers the opportunity to test their address verification software packages and, after achieving a certain percentage of compliance, to be CASS certified by the Postal Service. CASS does not measure the accuracy of ZIP+4 delivery point, five-digit ZIP®, or carrier route codes in a mailer's existing files. CASS enables mailers to measure and diagnose internally written, commercially-available, address verification software packages. The effectiveness of service bureaus' matching software can also be measured.

CASS certification is very difficult to achieve. CorrectAddress® has been tested in numerous categories and scored over 98% in order to earn the USPS certification and become CASS certified. Software vendors need to get CASS certified annually. Some of the categories include:
