 The new formula of this tournament coincided with a complete overhaul of the Nacional de Clubes system, so the competition was contested by only 4 teams, 2 from the Torneo del Interior and 2 from URBA.That format remained until 2013, when the UAR announced that after a three-year hiatus, the Nacional de Clubes would return with the original 16 team format since the 2014 edition, with 9 qualifying from the Torneo del Interior and 7 from the Buenos Aires Union.The "Nacional de Clubes A" is contested by 16 clubs from the best placed teams of URBA and regional tournaments.
