How are ball numbers decided for FA Cup draws?

The Football Association bases the ball numbers for each FA Cup draw primarily on the tie numbers from the previous round.

For example, the first two teams drawn out of the hat in the third-round draw will be tie number one. The winner of that game will subsequently be ball number one in the fourth-round draw.

Wolves, who progressed with a 6-1 win against Shrewsbury, will be ball number one in this season's fourth-round draw as they were involved in tie number one.

This system is used throughout the competition at various stages, but with a couple of exceptions.

For the third-round draw, when 44 Premier League and Championship clubs enter, teams take numbers one to 44 in alphabetical order.

The remaining 20 ball numbers are given to the winners of the previous ties, so the winner of tie number one in the FA Cup second round is ball number 45, for example.

This also happens in the first-round draw when teams from League One and League Two enter the competition. Those 48 teams take numbers one to 48 in alphabetical order and the remaining spots are selected in tie number order.
