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.
2018 FIFA World Cup
Of the 32 nations qualified to play at the 2018 FIFA World Cup, 20 countries competed at the previous tournament in 2014. Both Iceland and Panama qualified for the first time, with the former becoming the smallest country in terms of population to reach the World Cup. Other teams returning after absences of at least three tournaments include: Egypt, returning to the finals after their last appearance in 1990; Morocco, who last competed in 1998; Peru, returning after 1982; and Senegal, competing for the second time after reaching the quarter-finals in 2002. It is the first time three Nordic countries (Denmark, Iceland and Sweden) and four Arab nations (Egypt, Morocco, Saudi Arabia and Tunisia) have qualified for the World Cup.
