Team Melli have arranged friendly matches against Bosnia and Herzegovina as well as Bahrain.
Iran are in the driving seat in Group E after collecting four points from the first two games – a 6-0 thrashing of Sarajevo and a goalless draw with Thailand.
They can virtually seal their place at the competition with two wins against Jordan in November.
Afshin Ghotbi will take his men to Sarajevo on August 12 for a warm-up with the European team and then they will travel east to play in Manama on August 31.
According to the homepage of the Asian Football Confederation, Iran are also talking to Uzbekistan and Oman with regard to arranging preparation games.
