In fact, Mike, you have made a real effort despite the opinions of a very small
minority of vocal complainants.

Politics - nothing to do with common sense :/ One thing though; the
three capitals - London for England, Edinburgh for Scotland and
Cardiff for Wales - exist independently of the county/shire system, ie
the "state" field should be empty. (I just add an empty/ 'n/a' line to

These codes are new to me, but I wouldn't use them for addressing
postal mail and I've never them used for this. And it's correct that
the region is not needed - the house number and postcode give
enough information (not even the town or street are needed, and
if you give a computerised lookup system your postcode then they
only ask for your house number to get the final address).

In my home country of New Zealand we have postal codes but almost
never use them - just the suburb+town, or town+province is enough.
Australia is different again - eg, if you live in the suburb of Concord in
Sydney in the state of New South Wales, then the post office is very
adamant that you do *not* put Sydney on the address. They say it
should be suburb+ state+ postcode.
At the end of the day, it seems to me that the range of possible
variations is simply too large to try to second-guess. If people who
live in different parts of the world and have sorted out their local
system were to send you their personal lists for 'state.txt', then I would
suggest that you could include them along with a note to the effect
that "this requires local knowledge - edit to suit".
