The play-offs of the UEFA Euro 2020 qualifying tournament will decide the last four teams which will qualify for the UEFA Euro 2020 final tournament. Unlike previous editions, the participants of the play-offs will not be decided based on results from the qualifying group stage. Instead, 16 teams which failed to qualify through their group will be selected based on their performance in the 2018–19 UEFA Nations League. The sixteen teams will be divided into four paths, each containing four teams, with each play-off path featuring two single-leg semi-finals, and one single-leg final. The four play-off path winners will join the twenty teams which have already qualified for UEFA Euro 2020. The matches will take place between 26 and 31 March 2020.
With the new play-off format, the qualifying process will guarantee that at least one team from each division of the previous Nations League season will qualify for the final tournament.
The 16 teams will be selected based on their performance in the 2018–19 UEFA Nations League. These teams will be divided into four paths, each containing four teams, with one team from each path qualifying for the final tournament. Each league will have its own play-off path if at least four teams are available. The Nations League group winners will automatically qualify for the play-off path of their league. If a group winner has already qualified through the conventional qualifying group stage, they will be replaced by the next best-ranked team in the same league. However, if there are not enough teams in the same league, then the spot will go to the next best team in the overall ranking. However, group winners cannot face teams from a higher league.
As the final tournament draw takes place in November 2019 prior to the play-offs, should a host team qualify for the play-offs, a second final tournament draw may be required after the play-offs on 1 April 2020.
The 16 selected teams will then be allocated to paths of 4 teams. A draw will take place to allocate teams to the different paths, subject to the following conditions:
Group winners cannot form a path with a team from a higher league.
If four or more teams from a league enter the play-offs, a path with four teams from the league in question must be formed.
Additional conditions may be applied, subject to approval, including seeding principles and the possibility of final tournament hosts having to be drawn into different paths.
With these conditions, the draw procedure is as follows, starting with League D and working up to League A:
Form a path with four teams from the same league.
If there are more than four teams qualified in a given league, draw which teams will participate in the play-off path of that league.
Remaining teams are drawn into a path of a higher league.
If there are no teams from League A (i.e. they have all qualified directly for UEFA Euro 2020), then this procedure will result in four teams from lower leagues being allocated to the path of League A.
Each play-off path will feature two single-leg semi-finals, and one single-leg final, taking place in March 2020. Based on the Nations League rankings, the best-ranked team will host the fourth-ranked team, and the second-ranked team will host the third-ranked team. The host of the final will be decided by a draw in November 2019 between the two semi-final pairings.
The play-offs are played in single-leg knockout matches. If scores are level at the end of normal time, 30 minutes of extra time is played, where each team is allowed to make a fourth substitution. If the scores remain tied, a penalty shoot-out is used to determine the winner.
The qualifying play-off draw will take place on 22 November 2019 in order to determine the paths which the non-group winners will participate in. The host of the play-off final of each path will also be drawn between the winners of the semi-final pairings.
The following is the composition of the play-off paths:
