Which type of label is used for certified mail?

Certified mail is an important service offered by USPS that provides a receipt and allows the sender to confirm that the mail was delivered or that a delivery attempt was made. The process of certified mail adds an extra layer of security for documents that require proof of mailing and delivery.

Label 200 is specifically designated for certified mail. It is designed to be affixed to the mailing item, providing essential tracking information and confirmation of its delivery status. Once the certified mail is accepted by USPS, the sender receives a receipt, which serves as proof of mailing, and the recipient’s signature is obtained upon delivery, further enhancing the certification of that mail item.

The other labels—Label 100, Label 300, and Label 400—are intended for different postal services and purposes, such as other types of tracked mail or specialty services. Thus, they do not provide the specific features that are critical to certified mail, such as delivery confirmation and sufficient tracking capabilities.
