[1] On 9 June 2020, the Royal Spanish Football Federation announced that the play-offs are to be played in three locations of Andalusia.
They were drawn into a single game series where the two winners were promoted to the Segunda División.
For this year, the final which normally took place between the two winners to decide the overall champion of Segunda B was removed.
The six winners advanced with the two losing semi-finalists to determine the four teams that play for the last two promotion spots.
As the regular season was suspended due to the COVID-19 pandemic, the qualified teams were chosen according to the position after the last round played before the suspension.
