DAT-MAIL - Undocumented - Report Information

An Undocumented Piece Audit Report consists of two elements:

A CSV file containing the raw data compiled using the .txt file downloaded from IV-MTR (undocumented piece barcode data), along with the IM Piece Barcode data from DAT-MAIL (refer to DAT-MAIL - Undocumented - Report Information - CSV FILE).
A summary report categorizing the accumulated data and provides a total for each category (refer to DAT-MAIL - Undocumented - Report Information - Summary Report).

If your Company has not received an assessment notice, a sample is provided on the DAT-MAIL - Undocumented - Sample of Assessment Notice from the USPS page.
