Of the 47 AFC member associations, a total of 25 AFC member national teams entered the qualifying stage. The format is as follows:
First round: Excluding Japan, the five highest-ranked teams based on the June 2018 FIFA Women's World Rankings – which were Australia, North Korea, China PR, South Korea and Thailand – received byes to the third round. The next two highest-ranked teams – Vietnam and Uzbekistan – received byes to the second round. The remaining 18 teams were drawn into two groups of five teams and two groups of four teams, with the teams also seeded according to their FIFA Rankings. In each group, teams play each other once at a centralised venue. The group winners, runners-up and two best third placed advance to the second round.
Second round: The twelve teams (two teams who entered this round and ten teams from the first round) are drawn into three groups of four teams. In each group, teams play each other once at a centralised venue. The group winners advanced to the third round.
Third round: The eight teams (five teams who entered this round and the group winners from the second round) are drawn into two groups of four teams. In each group, teams play each other once at a centralised venue. The top two teams of each group advance to the play-off round.
Play-off round: The group winners play against the runner-ups of the other third round group on a home-and-away basis. The two winners qualify for the Olympic Football Tournament.
Play-off ties are played on a home-and-away two-legged basis. If the aggregate score is tied after the second leg, the away goals rule is applied, and if still level, extra time is played. The away goals rule is again applied after extra time, and if still level, the penalty shoot-out is used to determine the winner (Regulations for the 2020 Olympic Football Tournaments, Article 19.6).
The draw for the second round of the qualifiers was held on 13 February 2019, 16:00 MYT (UTC+8), at the AFC House in Kuala Lumpur, Malaysia. For the second round, the twelve teams were drawn into three groups of four teams. The teams were seeded according to their latest FIFA Rankings. The three teams which originally indicated their intention to serve as qualification group hosts (Myanmar, Palestine and Uzbekistan) prior to the draw were drawn into separate groups.
All matches were held in Qatar (neutral venue host); matches were originally to be held in Palestine, but were moved as Iranian citizens were banned from entering Palestine territories by Iranian law.
The draw for the third round of the qualifiers was held on 18 October 2019, 16:00 MYT (UTC+8), at the AFC House in Kuala Lumpur, Malaysia. For the third round, the eight teams were drawn into two groups of four teams. The teams were seeded according to their latest FIFA Rankings. The two teams which originally indicated their intention to serve as qualification group hosts prior to the draw (China and South Korea) were drawn into separate groups (this was already ensured due to them being in the same pot).
(H): Qualification third round group hosts (* Australia replaced China as group hosts after the draw)
(W): Withdrew after draw
The third round was originally scheduled to be played between 3–9 February 2020. However, the schedule of Group B was extended to 3–13 February 2020 due to a shift for the Group B hosts to Australia and the quarantine requirements of members of the China national team as a result of the 2019–20 coronavirus pandemic.
On 29 January 2020, after the announcement of the venues and kick-off times, and upon their arrival in Australia, the Chinese team and staff were subject to quarantine at a hotel in Brisbane for a term set to end on 5 February, after the first games were scheduled to be played. On 31 January 2020, Football Federation Australia published the amended match schedule which allowed China to play their first match after the quarantine had ended. Further changes to the schedule were announced on 2 and 5 February 2020.
The play-off round is scheduled for 6 March 2020 (first legs hosted by third round group winners) and 11 March 2020 (second legs hosted by third round group runners-up). The two play-off round winners will qualify for the 2020 Summer Olympics.
