For each round of the competition in which an association is participating, it must provide the UEFA administration with a final list of 20 players (surnames, first names, club and date of birth) as well as the surname, first name and coaching qualifications of the head coach and assistant coach. Two of these 20 players must be goalkeepers. In addition, this list must include the confirmation by one of the national association's doctors that all players have undergone the requested medical examination. This list must be completed online by 12.00CET the day before a team's first match in the relevant mini-tournament or by 24.00CET two days before a team's first match in the final tournament. Amendments to this list are not allowed after this deadline with the exception of.
For age and identity verification purposes, printed and signed copies of the final lists of 20 players and the players' passport/identity cards must be handed to the UEFA match delegate at the tournament organisational meeting the day before the start of each mini-tournament. For the final tournament, a printed and signed copy of the list and each player's passport/identity card must be handed to the UEFA match delegate or a representative of the UEFA administration by the time determined by the UEFA administration and communicated to the teams at the final tournament workshop.
For identification purposes, a UEFA representative makes a visual check of each player participating in the competition. As a rule, one such visual check takes place at a mealtime at the teams’ accommodation before a team's first match in each mini-tournament and the final tournament.
For the final tournament, a maximum of one outfield player named on the final list of 20 players may be replaced upon submission to the UEFA match delegate of written medical evidence of illness or injury in one of UEFA's official languages, no later than three hours before the start of the team's first match. The replaced player can take no further part in the final tournament and no other outfield player may be replaced during the final tournament. However, goalkeepers may be replaced at any time during the mini-tournament or final tournament upon submission to the UEFA match delegate of written medical evidence of illness or injury in one of UEFA’s official languages before the start of a match. In cases of particular hardship and upon reasoned request, the UEFA General Secretary may grant exceptions.
The eight official 20-player lists for the final tournament are published by the UEFA administration.
The associations are responsible for ensuring that the aforementioned provisions concerning player eligibility and lists of players are observed.
