Manifest for USPS Certified Mail - Firm Sheet Form 3877
If three or more Certified Mail letters are mailed at the same time, you will need to provide Form 3877 called a Firm Sheet or manifest. Our 3877 is computer-generated and contains the same information as Form 3877 that is approved by the local postmaster. We suggest having the firm sheet or manifest round-date stamped and signed by the USPS acceptance person. This serves as your proof of letter acceptance to the Postal Service. This report becomes your receipt of mailing. Any alterations made to this report must be initialed by the mailer and accepting USPS employee. All unused portions of the addressee column must be obliterated with a diagonal line.
