A total of four teams played in the preliminary round. As the draw was held before the UEFA entry deadline and the participating teams were not yet confirmed, only the associations of the teams were used, and seeding of teams was based on their association coefficients instead of their club coefficients. For the semi-final round, two teams (from associations 52 and 53, Northern Ireland and Kosovo) were seeded and two teams (from associations 54 and 55, Andorra and San Marino) were unseeded. The first team drawn in each tie in the semi-final round and the final round would be the administrative "home" team.
