What is return service requested?

Return service requested is a service offered by postal services and courier companies to send a package or mail back to the sender if it cannot be delivered to the recipient for any reason. This service is useful in cases where the recipient has moved, and their address is unknown or incorrect. If the mail or package is undeliverable, it will be returned to the sender with a notification that the address was incorrect or the recipient did not claim it. The return service requested entails an additional fee that is charged to the sender. The sender can specify the mode of return service, either by standard mail or express, depending on the urgency and importance of the document or package. Overall, return service requested saves time and effort associated with repeatedly attempting to deliver the package or mail to the wrong address.
