UEFA has introduced a revised qualification process for the 2028 edition to accommodate the unique host arrangement. A total of 24 teams will participate in the final tournament. The pathway to qualification begins with traditional group stages, where 12 group winners and eight of the highest-ranking second-placed teams will qualify directly. That accounts for 20 of the 24 available spots. The remaining four slots will be filled through a combination of host nation backup allocations and a play-off round that includes Nations League group winners and non-qualified runners-up.
In recognition of the challenge posed to host nations without the benefit of automatic qualification, UEFA has reserved up to two places for the best-performing hosts who do not qualify through their groups. These nations will be ranked based on their performance in the qualifiers, and the top two among them, if necessary, will be awarded spots in the final tournament. However, if fewer than two of the host nations fail to qualify outright, the leftover spots will be reallocated via an elaborate play-off format that considers results from the 2026–27 UEFA Nations League.
