Our CASS™ software codes all records during the certification run and these codes can give clues as to why a particular record may not be deliverable including an address that no longer exists. By default, we remove all records that do not fully code and can provide these back to you upon request, along with their error codes and a code sheet to help you complete these records for future use.
