Of the 23 participating teams, the top nine teams based on the April 2021
FIFA Ranking directly qualified to the group stage, while the remaining 14 teams played seven single-leg matches, with seven teams going through to the group stage. In the group stage, there were four groups of four teams in a
round-robin format, with the top two teams from each group qualifying to the knockout stage, which consisted of quarter-finals, semi-finals, a play-off for third place, and the final. The 14 teams in the qualifiers were paired based on their April 2021 FIFA Ranking:
Lebanon, the second-highest ranked team, played against
Djibouti, the second-lowest ranked team, and so on. The
Algerian FA decided in July 2020 to send the
Algeria A' (local) team, however, their final squad included players from other Arab leagues to strengthen the team. The
Moroccan FA also decided to send the
Morocco A' (local) team, however, they also later strengthened the team with players from other Arab leagues. Saudi Arabia participated with the
Olympic team. Note: Numbers in parentheses indicate positions in the
