Have you ever wondered why your parcel wasn’t delivered and got a Royal Mail card instead? You’re not alone.
Many people face the item retention Royal Mail process but don’t fully understand it. This blog will explain it simply, so you know exactly what to do next time.
What is Item Retention Royal Mail?

When Royal Mail can’t deliver a parcel or letter, they retain (hold) the item at the delivery office. This usually happens because:
- No one was home to sign for the item.
- The address was incomplete or unclear.
- The item was too big for the mailbox.
The item retention Royal Mail process ensures your package is safe until you pick it up or arrange redelivery.
Why Does Royal Mail Hold Items?
Sometimes, you might wonder why they didn’t just leave it at your door. Well, here’s why:
- Security reasons: Some items need a signature.
- Size limits: If the parcel is too large, they won’t force it into your mailbox.
- Delivery conditions: If there’s no safe place to leave it, they keep it for you.
According to Royal Mail’s official policy (you can read more here), they hold items for up to 18 calendar days before returning them to the sender.
