http://forum.geonames.org/gforum/posts/list/4.page JForum - http://www.jforum.net not need masses of information - latitude and longitude, area, population, regions etc. etc. - just the 3-digit country numbers and the names for all countries in the world. The actual system needs to look up the number and find the name (not the other way round) so a web service would have to work like this. What's the easiest, cheapest and best way of doing this? Can GeoNames do it?

There is no need for a web service or daily refresh because it is not common that a new country is introduced to the United Nations and get a new ISO Code. May be you can reload the list once or twice a year if your program needs an update anyway. Happy new year.
