The top team from each group qualifies automatically for the World Cup, with the runners-up going into the play-offs with four Nations League teams.
Those 16 play-off teams will be put into pots based on their records in the group and drawn into four paths with one-legged semi-finals and finals.
The games will be held over 10 matchdays during five international breaks.
Those international breaks are 21-25 March, 6-10 June, 4-9 September, 9-14 October and 13-18 November.
However no team will play World Cup qualifiers on all of those dates because there is a maximum of eight games. They can play friendlies on any free dates.
Some teams will start in March, others will start in June and four-team groups will not start until September.
Scotland and the Republic of Ireland, for example, will be playing Nations League promotion-relegation play-offs instead in March.
Teams who win the Nations League quarter-finals will not be in World Cup qualifying action until September.
The play-offs will be on 26-31 March 2026.
The World Cup will start on 11 June 2026 in Mexico City and end on 19 July in New Jersey.
The expanded 48-team tournament will last a record 39 days.
The new format will feature 12 four-team groups and a last-32 knockout round for the first time.
