Express 48 royal mail
A classic!
"48" is a postal code used by Royal Mail in the United Kingdom to indicate that a letter or parcel is to be sent by airmail to Europe, with a delivery time of 2-3 working days.
In more detail, the "48" code stands for:
- "4" indicates that the item is to be sent by air
- "8" indicates that the destination is in Europe
So, if you see "48" on a postal label or in a tracking update, it means that your item is being sent by airmail to Europe and should arrive within 2-3 working days.
