How to address mail to the UK

[anita_hillin]

You want off-topic?  I got yer off-topic right here!  

I'm trying to standardize a new database, and our mailing addresses to
folks in the UK are - well - all over the map, as it were.  Since a
fair number of you are either in the UK or likely mail to the UK,
what's the standard Country listing?  Our system uses England,
Ireland, and UK, seemingly in random order (some English addresses are
UK; some are England.  Ireland seems pretty consistently Ireland; I'm
presuming it would say Northern Ireland if it were supposed to be UK.)

Does it matter?  Am I fretting over nothing?  Or, should I change
England Scotland and Wales to UK?  (I don't think I have any N Ireland
addresses right now.) Enquiring minds want to know!

akh, who's grimly determined to whip this database into shape!
