It's grim up north (London)
there should be a free text box for the main address and one for the postcode that's it.
Which works fine if you're in the UK, but not in a lot of other countries - indeed most of them will break with this simplified format.
If you're in France, for example, the post code comes before the town. So you need to separate out the town from the rest of the address to be able to insert the post code before it.
e.g.
Siemens France said:150 avenue de la République
BP 101
92323 Châtillon Cedex
France
There's loads of variations.

You really need to capture the street, city (locality), province, post code and so on separately to be able to put them into the right order for each country.
