Frequently asked questions

Why hasn’t my tracking updated for 5 days after 'Item Leaving the UK'?
Once the mailbag leaves Langley HWDC, Royal Mail cannot scan the parcel while it is in the air or waiting in the destination country’s customs queue. The next scan occurs when the destination post opens the bag at customs.
Does my Royal Mail …GB tracking number change when it reaches the US, Canada, or EU?
No. The same 13-character S10 barcode ending in GB tracks all the way to final delivery on USPS, Canada Post, Australia Post, La Poste, Deutsche Post, and Correos.
