There are also authorized exchange shops in the airport or tourist areas where you can exchange your money at a bit more cost, but fast. These shops are called “SARRAFI” in Farsi which is the equivalent word for exchange. There are also street exchangers in tourist areas who usually hold a bunch of banknotes and show them to people who are passing and shout Dollars, Pounds, Euros.
