FIFA
In total, FIFA recognises 211 national associations and their associated men's national teams as well as 129 women's national teams; see the list of national football teams and their respective country codes. FIFA has more member states than the UN as FIFA recognises 23 non-sovereign entities as distinct nations, such as the four Home Nations within the United Kingdom and politically disputed territories such as Palestine.
FIFA 10
"FIFA 10" has 41 teams in its international division. The most notable exclusion is Japan (who made it into the round of 16 in the 2002 World Cup and the 2010 World Cup, but whose licensing rights currently belong to Konami). The following international teams are playable in the current generation consoles. But not all the teams are fully licensed e.g. South Africa and Russia.
