The hosts Bahrain and the top seven teams of the Men's U21 FIVB World Ranking in force at that time (as of 24 October 2022) were seeded in the first two positions of each pool following the serpentine system. FIVB reserved the right to seed the host team as head of pool A regardless of their position in the World Ranking. The remaining 8 teams were divided into three pots of four, according to their position in the same Boys' U19 FIVB World Ranking, in order to be drawn to complete the following two positions in each pool.
