Each league was split into three periods (of 10 matchdays each) which determined the twelve qualifiers for the promotion playoff.

The first round consisted of six matches of one leg opposing the twelve qualifiers from the Fourth Division.

The groups were constructed to ensure that the two teams from the third division were not able to meet each other in the playoff.

The matches were played in one leg at the venue of the first drawn team.

When a match ended in a draw, extra time of two periods of 15 minutes was played followed by a penalty shootout if the score remained tied.
