Lega Pro Seconda Divisione was the fourth highest football league in Italy, the lowest with a professional status.
Upon its inception in 1978–79, Serie C2 consisted of four divisions, however, that number was reduced to three from the start of the 1991–92 season.
The reform, already decided by the FIGC lead to the reunification with the first division starting from 2014–15 and with the subsequent rebirth of the third tier championship organized by the pro league with 60 teams divided into three groups of 20 in Lega Pro.
Each opponent was played twice, once at home, and once away, for a total of 34 matches.
In the last 17 matches, the same opponents were played in the same order, with the only difference being that the venue changed.
