The B. League revealed its conference allocations for the 2020-21 season following a meeting of its governors on Friday.

The circuit's top division (B1) will play with 20 teams in two conferences. The top division had consisted of 18 teams divided into three conferences since the league's inception in 2016.

The B. League abandoned the remainder of the 2019-20 season in March, with one-third of the campaign remaining, due to the COVID-19 outbreak. Because of the unusual circumstances, the league decided against holding its promotion/relegation playoffs and will instead add two teams to the top division for the upcoming season.
