Undue sanctions not only have crippled Iran’s economy, but also made money transitions from and into Iran extremely hard, if not impossible. Thus, you can’t use your credit or debit cards (Master and Visa Cards for example) in Iran. The solution is bringing enough cash in USD or Euro with which you can easily buy Iranian money.
Rial & Toman:
All the numbers written on our banknotes and coins are in Rial. Rial is the official currency of Iran, but, in daily life, people say prices in Toman. Each Toman equals 10 Rial.
The following instances give you a fair estimate about the real value of Rial/Toman:
There are different rates in Iran. One, famous as the official rate, is defined by the government and is very low (€1 is officially about Toman 5000). You would lose almost two third of your money if you exchange with this rate. The free market rate, though, is decided by supply-and-demand rule. By the time I modify this blog, 19th February 2020, each Euro is about Toman 15300, increasing from about 14100 a few weeks ago.
Tehran Exchange Center:
It is definitely the biggest exchange center of Iran, including hundreds of individual exchange shops which are located at Ferdowsi Avenue. The best way to get there is by metro; the metro station is called Ferdowsi St.
There are Iranian companies that offer touristic debit cards. They usually charge you an initial fee and up as much money as you want to your account. They also offer exchange service that I don’t advise you because their rate is always lower than the free market’s. We have no affiliation with any of them.
