Question

Answer 1

The BSI have BS 7666 - that covers all addressing. I recommend you look there.

The 2000 version recommends

An address shall be based upon a logical data model comprising the following entities:

1. addressable object, with sub-types:
   • primary addressable object;
   • secondary addressable object;
2. street;
3. locality;
4. town;
5. administrative area, a.k.a. district;
6. county;
7. postcode.
