Britain is still smaller if we can choose an arbitrary address.

S1 1AA

There will be hundreds of complete addresses with this pattern, and many thousands if we add a house number before it.

This is the first I found that is valid. It's the central post office in Sheffield.

Is that a ZIP code that maps to one specific building, or is it really a valid post address, matching any valid speicification, rules and laws?

In Austria we also have Buildings that have a 4-digit ZIP code. But it's not a valid address, because a valid address needs a city, street and house number. "5222 Ach 0" has it all ;)

It is a post code for a specific building/business, and it is therefore also a valid address. It will work. However, it is not the recommended address, which is:

  Royal Mail
  Sheffield Delivery Office
  Pond Street
  Sheffield
  S1 1AA

For large businesses to get discounted posting rates they must use the recommended address, presumably the redundancy makes for more reliable OCR and less effort for the postman at the point of delivery.

It's fairly common to use the abbreviated addresses when handwriting a return address.
