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 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.
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.
