"A full postcode is often much less than a single street."

My business has its own unique postcode and so does next door! Between us we cover roughly three acres. Our place is one building with parking and a fair bit of greenery.

There is apparently a suite to rent in the Rosewood Hotel in London (near Holborn) which has it's own postcode (WC1V 7EN).

To be fair it's a 6-bedroom wing, but still a fun fact.

My postcode in Surrey had about 7 houses according to the postie.
