The following team entries allocation was announced by the Union of Arab Football Associations on 20 June 2016.[1] Each association was given entry either to the qualifying play-off or to the group stage based on the FIFA World Ranking of the associations on 2 June 2016.[2] Only teams who were champions or runners-up of either their nation's league or one of their nation's cup competitions were allowed to participate in the tournament.
As the tournament's hosts (from the group stage onwards), Egypt were allocated two group stage slots as opposed to one, and Algeria were therefore allocated just one group stage slot rather than two.
The qualifying play-off was held between 14 September 2016 and 4 March 2017. The three winners of the play-off round advanced to the group stage to join the nine direct entrants.
From the group stage onwards, the tournament was held in Egypt in the cities of Cairo and Alexandria. Twelve teams participated in the group stage, divided into three groups. The draw for the groups took place on 5 May 2017 in Cairo.[4][5] The top team of each group along with the best runner-up advanced to the semi-finals.
