2-5 Key Codes

Key codes protect signature data files. After processing and approving a mailer’s participation request, the Postal Service provides the mailer or the third-party designee with the appropriate information, as follows:

1. If the mailer will receive its own records, the Postal Service Confirmation Services Customer Support team sends an e-mail to the customer point of contact with the mailer’s key code information.
2. If a third-party designee will receive a mailer’s records, the Postal Service Confirmation Services Customer Support team sends an
   e-mail to the third-party designee informing the designee of the mailer’s activation date for the program. The Postal Service will send the mailer’s records to the third-party designee using the third-party designee’s key code.
