All, A word of caution. In the discussion about ISO codes people mention alpha-2 and alpha-3 codes. Note that this only means the form of the code element, it doesn't says a lot about the type of the code. For alpha-2 codes there are the (1) Official Assigned and (2) Reserved codes. There are different types of reservation possible but the most important to note is that "While a code is reserved it will not be used in the standard to represent a country". In general, only official assigned codes are used for ccTLDs (although there are exceptions). The Glossary on the ISO site <http://www.iso.org/iso/country_codes_glossary.html> gives more details about the definitions of the types. And of course the standard itself. It is possible to find out which the various reserved alpha-2 codes are via the Online Browsing Platform (OBP) ISO <https://www.iso.org/obp/ui/#home> but the list of reserved alpha-3 codes is as far as I know not publicly available.
