You can withdraw cash in Iranian Rials (IRR) from almost all ATM machines. Any time a building has the word “Bank” in the title, you can find at least one ATM machine. Since all ATM machines in Iran are connected to Iran’s Central banking network called SHETAB, it does not matter which bank you choose to withdraw from. Most importantly, all ATM machines are equipped with English commands. Simply select your preferred language after entering your PIN number.
A bonus of the Tourist Card is that there are no withdrawal fees at any time.
There is however, a cash withdrawl limit of 2,000,000 IRR (~ €20/$30) per day.
