Do royal mail return undelivered letters

Yes, Royal Mail does return undelivered letters to the sender. Here's what happens:

1. Undeliverable mail: If a letter is undeliverable, Royal Mail will try to deliver it to the recipient's address again. If it's still not deliverable, they will mark it as "Return to Sender" (RTS).
2. Return to Sender: Royal Mail will then return the undelivered letter to the sender's address, usually with a note explaining why it couldn't be delivered. This is done at no extra cost to the sender.
3. Reasons for return: Undelivered letters are returned for various reasons, such as:
   • The recipient has moved and left no forwarding address.
   • The address is incorrect or incomplete.
   • The recipient has refused delivery.
   • The letter is too large or too small for the recipient's mailbox.
4. Timeframe: The timeframe for returning undelivered letters varies, but it's usually within 2-4 weeks from the date of posting.
5. Tracking: If you've used a tracked service, you can track the status of your letter online. If it's been returned to sender, you'll receive an update on the Royal Mail website.

To minimize the risk of undelivered letters, make sure to:

• Double-check the recipient's address before posting.
• Use a correct and complete address, including postcode.
• Use a tracked service to monitor the delivery status.
• Update your address book if the recipient moves.
