Should the "Autonomous communities" be included on this page? The codes don't seem to fit the format, although they are mentioned on the ISO newsletters. --Phil | Talk 11:15, Feb 24, 2005 (UTC)

=================================

In Spain, Spanish is everywhere an official language, there are no regions where the regional language is the sole official language. They are co-official.

The page is just wrong, as is the page for Albania (and maybe others). The codes do fit the format, it is simply that in some cases 3166-2 describes a hierarchy and in those cases the top level codes are shown stripped of their country prefix.

3166-2:ES describes three types of entity. autonomous communities, provinces categorised by autonomous community, and African cities.

Sorted alphabetically by province within community, the correct situation for Spain is:

Autonomous Community (#provinces)Province(s)
ES-ANAndalucía (8)ES-ALAlmería
  ES-CACádiz
  ES-COCórdoba
  ES-GRGranada
  ES-HHuelva
  ES-JJaén
  ES-MAMálaga

ES-VCValenciana, Comunidad (3)ES-AAlicante
  ES-CSCastellón
  ES-VValencia
Autonomous cities in North Africa (2):ES-CECeuta
  ES-MLMelilla

Note that with the exception of the Balearics (IB/PM), whenever a Community maps to a single province the upper and lower level codes are the same. Additionally the above table shows the correct labels which are also a key part of the Standard!

Hope that helps. Can somebody please rewrite the article accordingly? Chris Dent
