Leagues A and B consist of teams with a license from the Voetbalfederatie Vlaanderen (VFV, the Flemish/Dutch speaking wing of the Belgian FA), while league C contains teams with a license from the Association des Clubs Francophones de Football (ACFF, the French speaking wing of the RBFA).
In division A, champions Sint-Eloois Winkel and runners-up Mandel United together won all periods.
As a result, Mandel United was joined in the play-offs by the next three teams in the standings: Petegem, Gent-Zeehaven and Wijgmaal.
The team finishing in second place in the Second Amateur Division C will take part in the promotion playoff first round together with three period winners.
As champions La Louvière Centre won all three periods, this implied that normally the teams in positions 2 through 5 would take part in the playoffs, however both Hamoir and Rebecq were replaced as they did not receive (or apply for) a licence.
The two winners of the Promotion play-offs on the VFV side (Ronse and Wijgmaal) and the winning team from the ACFF Promotion play-offs (Visé) will play a final tournament together with the team that finished in 14th place in the 2018–19 Belgian First Amateur Division (Oudenaarde).
In case Oudenaarde, taking part in the Second Amateur Division Promotion play-offs Final and also from VFV side is also relegated and is replaced by a team from ACFF side, then a second VFV team will be relegated from the 2018–19 Belgian Second Amateur Division.
