QA: Validate key elements of your mailing BEFORE starting production!


Avoid assessments for inadequate By/For identification, incorrect or missing NPAs, STIDs, outdated Labeling List data and duplicate Intelligent Mail barcodes.

If PostalOne! rejects a mailing, or if you are notified of an error, or still worse, if your Mailer Scorecard reflects assessable errors, corrective action necessary can be painstaking to resolve the problem(s). And, adding another level of pain to the process, the mailer must cancel the statement, change or populate the correct matching Permit or NPA and resubmit. This is extremely inefficient. With the DAT-PreCheck solution, you can remove all the headaches – again - before you ever go into production or submit that file to PostalOne!

Make sure the following are correct:

  • Mailer Identification numbers (MIDs) and Customer Registration Identification numbers (CRIDs)
  • Nonprofit Authorization Numbers (NPAs)
  • Service Type Identifiers (STIDs); to match what is on the mailpiece
  • Labeling List file dates used to create your Mail.dat file are current
  • No duplicate Intelligent Mail (IM) barcodes in your Mail.dat file

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 and validates the Labeling List file dates that were used during the presort process. The newest addition to this great validation tool is the ability to detect duplicate Intelligent Mail barcodes (IMbs).

  • Helps mailers comply with Full-Service® requirements
  • Avoid common causes for Mailer Scorecard errors
  • View the Mail Owners identified in your Mail.dat file and determine if they are correct
  • Identify problems that could lead to By/For conflict errors
  • Pinpoint NPA issues, STID issues, or outdated Labeling List file dates
  • Detect if IMbs have been duplicated—BEFORE you mail!

Added Bonus: saves IM barcode data in the cloud so you can compare barcodes to multiple jobs, not just within a single job!


Think of DAT-PreCheck as an early warning system!

DAT-PreCheck warns of By/For conflicts and show mailers what the “primary” mail owner identifier was based on a list of processing priorities. It can also show mailers any conflicts with the STIDs being used, outdated Labeling List data, and duplicated IMbs so corrective action can be taken before going into mail production or uploading the Mail.dat files to PostalOne!
