I'm searching for a data set that contains the country information (Name, ISO 2 char, ISO 3 char, ISO number, ...) and other data. Also I'm looking for all states for each country including their abbreviation.
I'm willing to pay for that data if it is verified, actual and gets updated from time to time. I've already tried searching but couldn't find anything reliable.
Please note that I don't need geographical information directly but just a table of the data above.
