Missing 3 country codes about country-codes HOT 2 OPEN

Hi Evan. I've been working on aggregating, validating and producing my own country code/dial code list for a few days now as part of new screening/filtering logic we are implementing to validate phone numbers. It's a combination of the php-port of googles libphonenumber, public domain country/region lists, iso csv's, and some proprietary industry data we subscribe to as a telecom carrier. There always seems to be a handful of discrepancies, errors or omissions on pretty much every data source I find, which is to be expected.  So I've been parsing everything I can find against everything else I can find, and finding the odd-balls. For example, one industry data source uses AN for Antigua when most use AG.  BV for British Virgin Islands vs VG, RT for Montserrat vs MS.. the list goes on. I guess a lot it has to do with the viewpoint/industry that you are in.  From my perspective it's from a telecom/ITU stand point. Anyway, if you'd like I can pass along the summarized output that I have come up with. Les
