The provincial leagues are divided into 9 regional league systems (one for each province, but Flemish Brabant and Walloon Brabant are merged and contain also the football teams from the Brussels Capital Region).
As such, there are nine leagues at the first level of the provincial leagues, namely the leagues of the provinces of Antwerp, East Flanders, Hainaut, Liège, Limburg, Luxembourg, Namur, West Flanders and finally the Brabant division containing teams from the Brussels Capital Region, Flemish Brabant and Walloon Brabant.
The regular season is thus composed of 30 matchdays, generally played on Sunday.
The first one is composed of two matches played by the four thirteenth placed teams of each league in Division 3.
