9-1.1 Postal Service employees must verify mailings either at the Post Office or at the mailer’s facility, as determined by the administering postmaster with concurrence of the district office. When verifications are done at the mailer’s facility, Postal Service employees must have sufficient time to verify the mail before the scheduled dispatches.
Scan the barcode on PS Form 3152, Confirmation Services Certification, for mailings using Confirmation Services. The PS Form 3152 may be included on the manifest rather than as a separate form.
