Does uk post office return undeliverable mail

In the UK, Royal Mail (the postal service) has a process for handling undeliverable mail. Here's what happens:

1. Initial attempts: Royal Mail will make two attempts to deliver the mail to the address specified. If the mail is not delivered on the second attempt, it will be returned to the sender as "undeliverable".
2. Undeliverable mail: If the mail is not delivered after two attempts, Royal Mail will return it to the sender as "undeliverable" with a reason code (e.g., "addressee not known", "address not found", etc.). This is usually done within 3-5 working days.
3. Return to sender: The undeliverable mail will be returned to the sender's address, which is usually the sender's postal address or the address of the sender's business.
4. Notification: Royal Mail will also send a notification to the sender, usually by email or letter, informing them that the mail was undeliverable and providing the reason code.

However, there are some exceptions and additional considerations:

• International mail: If the undeliverable mail is international, Royal Mail may not return it to the sender. Instead, they may hold it for a period of time before disposing of it.
• Large or bulky items: If the undeliverable mail is a large or bulky item, Royal Mail may not be able to return it to the sender. In this case, they may dispose of the item or store it for a limited time.
• Special services: For special services like tracked or signed-for mail, Royal Mail may attempt to contact the sender to arrange for redelivery or provide alternative delivery options.

It's worth noting that Royal Mail's policy on undeliverable mail is outlined in their "Undeliverable Mail Policy" document, which can be found on their website.
