[1] League D consisted of the lowest 16 UEFA members ranked from 40–55, who were split into four groups of four.

Four teams from League D which had not already qualified for the European Championship finals competed in the play-offs for each division, which were played in October and November 2020.

[7] The group draw took place at the SwissTech Convention Center in Lausanne, Switzerland on 24 January 2018, 12:00 CET.

[8][9][10][11] For political reasons, Armenia and Azerbaijan could not be drawn into the same group (due to the Nagorno-Karabakh conflict).

This meant that the maximum amount of solidarity and bonus fees for a team from League D was €1 million.
