The top eight teams from each division advance to the playoffs. Seeding is based on wins, with tiebreaker rules applied should multiple teams have the same record. The single-elimination bracket consists of four rounds with no reseeding. The first three rounds being best-of-three series and the national finals being a best-of-five series.

During the first two rounds, two games within the same division are played in a gameday, with homecourt advantage alternating between the higher-seeded teams of each series. A traditional homecourt format is then used for the last two rounds, with the division finals using a 1–1–1 format and the national finals using a 2–2–1 format. The designated home team may not be able to play within its home locality. Should it occur, the gameday may take place elsewhere.

Teams in bold advanced to the next round. The numbers to the left of each team indicate the team's seeding in its division, and the numbers to the right indicate the number of games the team won in that round. Teams with homecourt advantage, the higher-seeded team, are shown in italics.
