The 48 national teams were divided into ten groups (two groups of four + eight groups of 5). Each group winner, as well as the six highest ranked second placed teams, advanced to the play-off. One of the eight qualifiers was then chosen to host the remaining fixtures.
Qualifying group stage
Draw
The allocation of teams into qualifying groups was based on that of UEFA Euro 2004 qualifying tournament with several changes, reflecting the absence of some nations:
Groups 1, 2, 3, 4, 6, 9 and 10 featured the same nations
Because some groups contained five teams and some four, matches against the fifth-placed team in each group are not included in the ranking. As a result, six matches played by each team counted for the purposes of the second-placed table. The top six advanced to the play-off.
