U23EF

U23EF is an acronym that may refer to multiple organizations, programs, or initiatives related to football (soccer) involving players aged 23 and under. Because there is no single globally recognized body using the abbreviation, the exact meaning of U23EF varies by country, federation, or project.

In many cases, it is used for youth development efforts aimed at preparing players for senior national teams or professional leagues, often focusing on talent identification, training, and competitive opportunities for players under the age of 23. Common features across such uses include age-group governance, coaching education, and partnerships with clubs or leagues to align development pathways with national or regional football strategies.

Possible interpretations (non-exhaustive) include: a national under-23 development program organized by a football federation; a regional or inter-regional federation dedicated to under-23 competitions; or a donor or charity entity supporting youth football development. Because U23EF is not a standardized designation, readers should consult specific sources or the entity in question to determine its scope, governance, and activities.

If you can provide a country, organization, or context, this can be clarified into a concise, focused article. See also under-23 football, youth development in football, and federation governance.
