UK postcodes combine letters and digits, e.g. SW1A 1AA, split into outward and inward parts. Managed by Royal Mail, they can identify streets or even single addresses.

For cross-border e-commerce sellers, always verify the recipient's address and ZIP code before shipping, and check whether the destination is in a remote/outlying postal area — delivery costs can differ dramatically.
