Paraguay hosted the tournament for the third time after the 2004 and 2019 editions. All matches were played at the Centro de Alto Rendimiento de las Divisiones Formativas (CARDIF) located within the Parque OlÃÂmpico sports complex in Luque and opened in April 2024..
The teams were divided into two geographically based zones (North and South) to compete in a round robin against other members of their own zone during the group stage. In the final stage, the winners of each zone face each other in the final to contest the title, while the runners-up, third, fourth, and fifth place teams from each zone face each other to determine third through tenth place.
Each match had a regular playing time of 80 minutes divided into two 40-minute halves with a 15-minute break. At the end of each match, CONMEBOL implemented a third period in which members of both teams shared an educational and integration space before returning to the dressing rooms.
