It is played by teams from all over the country. Clubs from Buenos Aires surroundings, as well as some from Santa Fe province, are promoted from or relegated to the Primera B Metropolitana (Metropolitan B Division) while for teams from the other provinces the Torneo Argentino A (Argentine A Tournament) is the next level down. In the league system of Argentine football, Nacional B is the second-highest league, and from it the three best teams are automatically promoted to Primera División.
It was created in 1985 to integrate unaffiliated clubs into the of Argentine football structure, which until then had only participated in Nacional championships of Argentina's First Division tournament. It brought together teams from the old Primera B (until then, the second division) and regional leagues from several Argentine provinces.
After the 1985/86 season, the Primera B Nacional became the second hierarchical football league in Argentina's professional football, after the First Division, and it is above the Torneo Argentino A and the Primera B or Primera B Metropolitana, the last one started to act as a third division for the teams directly affiliated to AFA.
For the 2014 season, teams participating are divided into two zones, A and B, playing each other a double round-robin tournament, where every club plays every other club twice, once at home and once away for a total of 20 fixtures. Teams receive three points for a win, one point for a draw, and no points for a loss. Teams are ranked by total points. At the end of the tournament, the five best placed teams of each zone will directly promote to Primera División. There won't be relegations at the end of the season.
