A total of 28 teams registered for the event. The top 9 teams from the 2019 U-19 championship automatically qualified. The remaining teams automatically qualified based on World Rankings due to the cancellation of all qualifiers by the IFF due to the COVID-19 pandemic.[2]
In July 2021, it was announced that Australia, Canada, Japan, New Zealand, Norway, and Russia would be unable to participate, and Austria, Belgium, Estonia, Hungary, and Italy would take their place as replacement teams.[3]
As the number of teams in Group C & D was not equal then a ‘mini-tournament’ format will be used to decide the 13th–15th placings. The placings will be calculated by using the two 13th–15th placement matches plus the result from the Group C match between the teams involved.
The matches for 13th–15th place will be played only with regular match time – 3 x 20 minutes. No extra time or penalty shots.
