[4] Due to the decision of the Dutch government to forbid all gatherings and events until 1 June, this period was even further extended.
[1] Later on 12 June, the KNVB officially announced that the Derde Divisie would again consist of 36 teams from next season.
After the loss of the two reserve teams, the withdrawal of FC Lienden and the voluntary relegation of ONS Sneek, the two divisions of the third tier would have consisted of only 15 clubs each.
The Hoofdklasse group leaders, namely Sportlust '46, Staphorst, Hollandia and Unitas, therefore moved up to the Derde Divisie.
