Sorry to throw this at you again, as I can see that you've been struggling through the very special confusion that is the UK postal address - what serves as a county, in particular. The ones in the Hikashop list for Wales are a bit of a mix between very old and very new ones, and there's quite a bit of overlap (Blaenau Gwent is in Gwent, for example, and no-one uses Glamorgan as a postal county any more).
Lists of current administrative counties ([url=url=http://en.wikipedia.org/wiki/Metropolitan_and_non-metropolitan_counties_of_England]England[/url]), regions and districts (
Scotland
), principal areas (
Wales
) and districts (
Northern Ireland
) organised by local government are quite fluid - the Northern Ireland Executive is currently planning to reduce the number of districts to 11, and there's been talk of reorganisation in Wales for ages too.
There's no one, simple solution, (see this
discussion on Geocaching)
but the closest I've seen to county names that I would recognise are the ceremonial county names in the
Lieutenancy areas
. Using this list would mean there was no overlap between geographical areas. Some of them are a bit old-fashioned, but they're unlikely to be affected by legislation which redraws or reorganises county government boundaries, so would require less maintenance in the long-term.
Or you could just put the ability to edit UK counties in a plug-in
