What service can be added to certified mail?

  1. Signature confirmation

  2. Return receipt and restricted delivery

  3. Next day delivery

  4. Express delivery option

The correct answer is: Return receipt and restricted delivery

The addition of Return Receipt and Restricted Delivery to certified mail provides important enhancements to the service. When you request a Return Receipt, you get proof of delivery that includes the signature of the recipient, which can be pivotal for legal and formal communications. This service not only verifies that the mail was delivered but also documents who signed for it, thereby offering an extra layer of security and accountability. On the other hand, Restricted Delivery ensures that only the intended recipient can receive the mail. This is particularly useful for sensitive or confidential documents, where you want to guarantee that the person receiving the mail is the right individual. By combining these two features with certified mail, senders can ensure both delivery confirmation and recipient verification, making this choice the most comprehensive option among those listed. In contrast, services like next day delivery and express delivery options are primarily focused on the speed of delivery rather than the additional security features that certified mail already possesses. Additionally, signature confirmation, although useful, is not a service that can be added specifically to certified mail, as it is inherently part of the certified service itself. Hence, adding Return Receipt and Restricted Delivery significantly enhances the certified mail service, making it the optimal choice.
