Format

The four group winners have the opportunity to promote directly and become the overall Segunda División B champion. The four group winners will be drawn into a two-legged series where the two winners will be promoted to the Segunda División and will enter into the final for the Segunda División B champion. The two losing ''semifinalists'' will enter the playoff round for the last two promotion spots. The four group runners-up will be drawn against one of the three fourth-placed teams outside their group while the four third-placed teams will be drawn against each other in a two-legged series. The six winners will advance with the two losing semifinalists to determine the four teams that will enter the last two-legged series for the last two promotion spots. In all the playoff series, the lower-ranked club will play at home first. Whenever there is a tie in position (''e.g.'' like the group winners in the ''Semifinal Round'' and ''Final'' or the third-placed teams in the first round), a draw will determine the club to play at home first.
