The Pay at Mailing option requires that, prior to mailing, the mailer (or third-party designee) must send an electronic file that shows that the mailer (or third-party designee) has paid the extra service fee for the return receipt (Electronic) on the mailpiece. The mailer (or third-party designee) must pay postage using a postage meter or PC Postage. This fee information appears starting in Record Position 080 in Detail Record 1 of the electronic file.
The file must contain the appropriate special service code (06) and the appropriate fee. If the file does not indicate the correct fee, or if the Postal Service does not receive the file, or if the Postal Service refuses the file because of errors, then the Postal Service will not be able to provide the records for that mailpiece. (See Publication 91 or Publication 109 for details on special service codes and file errors.)
With this option, a mailer must provide information regarding a credit card account that the Postal Service charges each time that it compiles records. The Postal Service’s National Customer Support Center (NCSC) processes the payments. For example, if a mailer has chosen the Signature Extract File option, then each Monday morning when the Postal Service generates files the NCSC will charge the appropriate amount to the credit card account on file based on the number of records provided. If a mailer has chosen the CD-ROM option, then the NCSC will charge the appropriate amount to the credit card account on file on the first and fifteenth of the month when the Postal Service compiles the CD-ROMs.
