The AVC stated that there were originally eighteen entrant teams that were due to participate in the tournament. However, on 17 August 2023, Mongolia announced that they withdrew from the tournament.[2][3]
Teams were seeded in the first two positions of each pool following the serpentine system according to their final standing of the 2021 edition. AVC reserved the right to seed the hosts as head of Pool A regardless of the final standing of the 2021 edition. All teams not seeded were drawn in Bangkok, Thailand on 16 March 2023. Final standings of the 2021 edition are shown in brackets except the hosts who ranked 1st.[5]
Total number of victories (matches won, matches lost)
In the event of a tie, the following first tiebreaker will apply: The teams will be ranked by the most point gained per match as follows:
Match won 3–0 or 3–1: 3 points for the winner, 0 points for the loser
Match won 3–2: 2 points for the winner, 1 point for the loser
Match forfeited: 3 points for the winner, 0 points (0–25, 0–25, 0–25) for the loser
If teams are still tied after examining the number of victories and points gained, then the AVC will examine the results in order to break the tie in the following order:
Set quotient: if two or more teams are tied on the number of points gained, they will be ranked by the quotient resulting from the division of the number of all set won by the number of all sets lost.
Points quotient: if the tie persists based on the set quotient, the teams will be ranked by the quotient resulting from the division of all points scored by the total of points lost during all sets.
If the tie persists based on the point quotient, the tie will be broken based on the team that won the match of the Round Robin Phase between the tied teams. When the tie in point quotient is between three or more teams, these teams ranked taking into consideration only the matches involving the teams in question.
