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 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 Federal 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 2016 season, teams participating are playing each other a single round-robin tournament, where every club plays every other club once for a total of 21 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.
