DAT-PreCheck Software Update

DAT-PreCheck displays and validates the Mailer Identification numbers (MIDs) and Customer Registration Identification numbers (CRIDs) of the Mail Owners and Mail Service Providers identified in a Mail.dat® file. Additionally, DAT-PreCheck validates the Nonprofit Authorization Numbers (NPAs) for any mailing claiming nonprofit pricing. It also provides information outlining the Service Type Identifiers (STIDs) populated in the Mail.dat file. The newest addition to this great validation tool is the ability to validate the Labeling List file dates that were used during the presort process.

The beauty of all this is that it can be done very quickly – allowing you to save valuable time and money. And the best part is that you get the ability to validate this information before you submit Mail.dat files to PostalOne!®.

Bug Fixes:



B20106:  A client reported errors when submitting jobs to DAT-PreCheck. When they dropped the files with DAT-PreCheck already started, an immediate error “AutoFailed\**.zip is not found” was occurring.  Stopping the program, dropping the files and restarting it allowed them to be processed correctly.  This was investigated and confirmed as something that could happened under certain conditions.  A fix has been made.   Ticket  92239
