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 World Cup qualification
The FIFA World Cup qualification is the process that a national association football team goes through to qualify for the FIFA World Cup finals. The FIFA World Cup is the largest international team sport competition in the world with a qualification process required to reduce the large field of countries from 211 to just 32 for the World Cup finals.
