Teams are divided into four groups by geographical contiguity.

Promoted teams gain access to the second-tier Serie A2 Basket, while relegated teams get demoted to play in the Serie C Gold Basket.

Serie B Basket first began in the 1937–38 season as the second level of the Italian basketball league system, and it remained the 2nd-tier level of the Italian basketball pyramid until the 1954–55 season.

Since 2014, the league has once again been known as the Serie B Basket, and has once again been the third-tier level on the Italian basketball pyramid.
