Draw
The draw for the group stage was held on 6 December 2017, 14:00 MYT, at the AFC House in Kuala Lumpur, Malaysia. The 36 teams were drawn into nine groups of four: three groups each in the West Asia Zone and the ASEAN Zone, and one group each in the Central Asia Zone, the South Asia Zone, and the East Asia Zone. Teams from the same association in the West Asia Zone and ASEAN Zone could not be drawn into the same group.
The seeding of each team in the draw was determined by their association and their qualifying position within their association. The mechanism of the draw was as follows:

The remaining teams were then allocated to groups according to the rules set by AFC.
- For the ASEAN Zone, a draw was held for the five associations with two direct entrants to determine the three associations occupying seeds 1 and 2, with seeds 1 placed in order for Groups F, G and H, and the two associations occupying seeds 3 and 4, with seeds 3 placed in Groups F and G. The remaining teams were then allocated to the groups according to the rules set by AFC.
- For the Central Asia Zone, the South Asia Zone, and the East Asia Zone, no draw was held, and the teams were allocated to the groups according to their association ranking published on 30 November 2016.
