The South American section of the 2018 FIFA World Cup qualification will act as qualifiers for the 2018 FIFA World Cup, to be held in Russia, for national teams which are members of the South American Football Confederation (CONMEBOL). A total of 4.5 slots (4 direct slots and 1 inter-confederation play-off slot) in the final tournament are available for CONMEBOL teams.
The qualification structure is the same as the previous five editions. The ten teams will play in a league of home-and-away round-robin matches. The top four teams will qualify for the 2018 FIFA World Cup, and the fifth-placed team will advance to the inter-confederation play-offs.
Unlike previous qualifying tournaments where the fixtures were pre-determined, the fixtures will be determined by draw, which will be held on 25 July 2015, at the Konstantinovsky Palace in Strelna, Saint Petersburg, Russia
Qualification starts in early October.
