What does "RTS" stand for in postal operations?

In postal operations, "RTS" stands for "Return to Sender." This term is commonly used to indicate that a piece of mail cannot be delivered to the intended recipient and is being returned to the original sender. Various reasons might cause mail to be classified as RTS, including incorrect addresses, the recipient no longer residing at the address, or refusal of delivery by the recipient.

Understanding "Return to Sender" is crucial for postal workers, as it helps streamline the process of handling undeliverable mail. Implementing proper RTS procedures allows for better tracking and management of mail that cannot be delivered, ensuring that it is efficiently returned to senders and preventing delays in service.

The other choices, while they may contain terms used in postal operations, do not accurately reflect what "RTS" specifically indicates within the context of postal services. They relate to different aspects of mail processing and logistics.
