A certified letter should include the name and mailing address of the recipient, the senders return address and the time and date of mailing. The information must be entered into a certified mail form 3800.
Certified mail is a service offered by the United States Postal Service, or USPS, to provide documented proof that letters or packages are delivered to the intended recipient at a certain date and time. Certified mail form 3800 is a label that must be affixed to the certified letter or package. It should be placed between the stamp and the return address at the top of the envelope or package.
Restricted delivery is an extra service where the sender can indicate that the letter only be delivered to the intended recipient. Senders can also request a return receipt, which provides confirmation when the package is delivered. A return receipt includes a copy of the signature or an electronic signature stamp of the person who signed for the package.
Certified mail forms and receipts are available at any post office or online from the USPS website. Extra postage is required for certified mail, including extra fees for return receipts and restricted delivery. Certified mail can also be tracked online or by phoning the post office.
