Hosts England, Ireland, Scotland, and Wales will compete in the 2028 European Championship qualifiers, UEFA announced on Wednesday.
While all four will participate in separate qualifying groups, only two reserved spots will be available for the best-ranked host nations who fail to qualify directly.
This decision, made by the UEFA Executive Committee, means 20 teams will qualify directly as group winners or best runners-up.
The remaining spots will be filled via playoffs, with the number of playoff berths varying based on how many host nations utilize their reserved spots.
EURO 2028 will be held across nine venues in the United Kingdom and Ireland.
