Take your addressed mail to the post office and request either first-class mail or priority mail along with certified mail service.
Enter the name and address of the recipient onto Form 3800 using legible handwriting.
Check the box indicating a request for a return receipt if you want one. Find the portion of the certified mail form that the mail carrier detaches after delivering the letter. Copy the certified mail number into the proper blank on the detachable portion, and write your name and address in the blanks provided. You will receive this receipt after the mail carrier delivers the certified mail.
Place the proper portage onto the envelope, including any certified mail fees and other mailing fees.
Give the mail to a USPS counter employee for mailing.
