The ICC World Twenty20 2012 will be contested by 12 teams which have been 'seeded' and divided into four groups:

*If a team seeded third in the group qualifies for the Super Eight, it will adopt the code of the team they have replaced. For example, if Q2 qualifies at England's expense in second place in group A, it would be A1 and India still A2. No points are carried forward to the Super Eight stage, and the top two teams in each Super Eight group will qualify for the semi-finals.
