The USPS CASS Detailed Report does not need to be given to the USPS to qualify for certain discounts. This report contains some of the same information as the 3553 report but provides much greater detail about DPV, LACS, and SuiteLink statistics.
For more information about CASS settings see CASS Certified Processing. For instructions on how to use reports, see the Spectrum Technology Platform Dataflow Designer Guide.
