In plain English
These letters, numbers, or a mix of both help narrow an address to the right area or even a specific delivery point. Postal services use them to sort and direct mail correctly.

- Situation

Meaning limits
The term itself does not say whether the code points to a larger area or to a single delivery point, because that can vary.

“The agent asked for our postcode before taking the rest of the address.”
