The best ranked NOC in each of the 6 Continental Qualification Tournaments will obtain quota place. 2 quota per each gender are giving to AFC, UEFA, CONCACAF and CONMEBOL and 1 quota per each gender are giving to CAF and OFC.[2]

The draw was held on 24 August 2018, 18:30 ART (UTC−3), at the Casa de Gobierno de la Ciudad de Buenos Aires in Buenos Aires.[26] In both the boys' and girls' tournament, the ten teams were drawn into two groups of five teams. The hosts Argentina were assigned to position A1 in the boys' tournament. As teams from the same confederation could not be drawn into the same group, the two teams each from AFC (Asia), CONCACAF (North America), CONMEBOL (South America), and UEFA (Europe) were drawn into different groups, and as a result the two remaining teams, one each from CAF (Africa) and OFC (Oceania), were also drawn into different groups.[27]
Match officials
A total of 24 officials (18 men and 6 women) were appointed by FIFA for the two tournaments.[28][29]
Each team had to name a preliminary squad of 20 players (minimum three must be goalkeepers). From the preliminary squad, the team had to name a final squad of 10 players (minimum two must be goalkeepers) by the FIFA deadline.[1]
