Products affected: PBFirst™, ConnectRight™ Mailer


When trying to send the Mail.dat file in PBFirst™, PBFirst fails to send the Mail.dat and displays the following error message:
There is an invalid .mpa Permit Number and .mpa Postage Payment Method combination; the Permit Number must reference an active permit for the associated payment method at the .mpa Permit ZIP+4 code in the .mpa file.


The secondary payment method permit imprint number is missing if using precanceled stamp or meter mail.


A Permit Imprint account is required.

Section 2.3.4 Additional Postage of the USPS Postal Service Mail.dat Technical Specification states that "When postage affixed (precanceled stamp or meter) is used, the file must include a separate MPA record. This separate MPA record MUST be linked to a Permit Imprint account; Postage Payment Method must be a ‘P’."

If your company does not have an additional Permit Imprint number available, you can apply for a Permit Imprint.
