What about the remaining three slots?
The final European berth is due to be decided in June with Scotland facing Ukraine in a semi-final playoff and the winners taking on Wales. Scotland’s manager, Steve Clarke, has suggested those games could be subject to further delay.
The other two places will go to the winners of intercontinental playoffs, contested on 13-14 June in Qatar, with Costa Rica facing New Zealand and Peru taking on the UAE or Australia, who first play the Asian confederation playoff in Doha on 7 June.
How will the draw work?
The teams are divided into four pots based on the Fifa rankings published on Thursday. Pot 1 included Qatar as hosts and the seven highest-ranked qualified teams. Pot 2 has the next eight highest-ranked qualified teams, Pot 3 the eight highest-qualified after that, and Pot 4 the five best-ranked teams after that and placeholders representing the two winners of the intercontinental playoffs and the remaining European playoff winner.
Jar 1 Qatar, Brazil, Belgium, France, Argentina, England, Spain, Portugal.
Jar 2 Mexico, Netherlands, Denmark, Germany, Uruguay, Switzerland, USA, Croatia.
Jar 3 Senegal, Iran, Japan, Morocco, Serbia, Poland, South Korea, Tunisia.
Jar 4 Cameroon, Canada, Ecuador, Saudi Arabia, Ghana, Wales/Scotland/Ukraine, Costa Rica/New Zealand, Peru/UAE/Australia.
Each World Cup group will contain one team from each pot. First each team in Pot 1 will be allocated a group, then each team in Pots 2, 3 and 4 to create eight groups of four. Each pot will be emptied before the next pot is drawn. Qatar will be allocated position A1 but in every other case a ball will be drawn from a team pot, then a ball drawn from a group pot to determine where they will be placed.
Teams from the same confederation will be kept apart in the groups with the exception of European teams, of which there will be 13. Five of the eight groups will have two European teams.
When will the tournament take place?
It runs from 21 November to 18 December at eight venues.
