The group comprised the third level of the Bulgarian football pyramid and was divided into four geographic regions: North-West, North-East, South-East, and South-West.
The 2015–16 season was notable for the participation of CSKA Sofia and Lokomotiv Sofia in the South-Western region, as the two teams were unable to obtain a license for the A PFG due to unpaid debts, which led to their administrative relegation.
The champions of the four 2014–15 V AFG divisions were promoted to the 2015–16 B Group: Dunav Ruse from V AFG North-East and Pomorie from V AFG South-East, Spartak Pleven from V AFG North-West and Oborishte Panagyurishte from V AFG South-West.
In return, four teams were relegated to the V AFG: Botev Vratsa, Chernomorets Burgas, Rakovski and Spartak Varna.
Kanal 3 is the TV partner of the V group.
