The league started in 1989-1990 and was named TFF PAF Ligi (Profesyonelliğe Aday Futbolcular) until 2008-2009 season. The 1993-1994 season was called TFF BAL Ligi (Deplasmanlı Bölgesel Altyapı Ligi). Since the 2009-2010 season, it has been called TFF A2 Ligi.
Teams are not relegated from the TFF A2 Ligi based on their final league position, but on the league position of their respective clubs' senior teams. If a senior team is relegated from the 1. Lig, then the reserve team is relegated from the A2 Ligi and replaced by the reserve team of the promoted team from the 2. Lig.
Until the year 2009, only A2 teams of the Süper Lig could participate in the A2 ligi. Since the 2009-2010 season, 1. Lig teams could have participated and therefore the league is split into a western (20 teams) and eastern group (18 teams) and the winner of each group play a final match.
