Do you know of anywhere I could get an abbreviated list of all acceptable provinces of the world? I've been trying to find it on the web, and believe it or not, this information is not easy to come by. I have contacted authorize.net to see if they have a list of any and all countries and province they accept during successful checkout. Hopefully they'll have some information for me. If not, do you or your team know from what list and from where we could populate our checkout pages with valid abbreviations?
