At the UEFA conference in January 1976, the age limit was lowered to 21 for the 1978 tournament, and has remained so ever since. The rules at the time allowed each team to field two players over the age of 21. To be eligible for the campaign ending in 2027, players must be born in 2004 or later. Many may actually be 23 years old by the time of the final tournament; however, when the qualification process began (2025), all players would have been 21 or under.
