The next four eligible teams in each group played in the promotion play-offs.[3]
The champion of each group qualified for 2022–23 Copa del Rey. If the champion was a reserve team, the first non-reserve team qualified would join the Copa.
In each group, at least three teams were relegated to regional divisions; the relegation of each group was configured so that all Tercera División RFEF groups would have 16 teams for the 2022–23 season.

Copa del Rey qualification
25 teams qualified for the 2022–23 Copa del Rey: the best teams in each group (excluding reserves) and the 7 best second-placed teams ranked by their points coefficient. Should any second-placed team among these 7 qualify already as the best non-reserve team in its group, a ranking of third-placed teams would fill the remaining vacants.
