The Paraguayan Third Division is divided into three leagues:
The Primera División B Nacional tournament is being played since 2011. Teams from the all Paraguay's departament (except Asunción and Central department) take part in this third division league.
The Primera División B (metropolitan tournament) is being played since 1939. Since that year, the number of teams, rules and names for the tournament have changed, but as of now it's called "Primera de Ascenso" and 16 teams take part.
Only teams from the Gran Asunción metropolitan area and Central Department take part in this third division league. Teams from all other parts of Paraguay that are not part of the Gran Asunción area play the Primera División B Nacional tournament in order to get promoted to the Paraguayan Division Intermedia.
