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 Federal A ("Federal 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.
Primera B Nacional games are often transmitted to Argentina and abroad on television by TyC Sports.
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 league in Argentina's professional football, after the Primera División, and it is above the Torneo Federal A and the Primera B Metropolitana, the last one started to act as a third division for the teams directly affiliated to AFA.
For the 2016–17 season, the twenty-three participating teams played each other twice for a total of forty-six matches. Teams received three points for a win, one point for a draw, and no points for a loss. Teams are ranked by total points.
The champion and runner-up teams automatically promoted to Primera División. Four teams were relegated at the end of the season.
