Financial Issues in Traveling to Iran
The currency used in Iran is the Iranian Rial which is actually Toman. In fact they’re not two currencies, official rates are announced in Rial but in daily life Toman is used instead which has one zero less. For example 10.000 Rials is equal to 1.000 Toman. Do not lost; it takes a couple of days to get used to. Finally if it troubled you in paying just ask the seller whether the rate is in Rial or Toman.
Exchange rate is not fixed in Iran like many other countries. Remember the
official exchange rate is different from real exchange rate; the official one is lower. It’s highly
recommended to travel to Iran with cash and exchange it in currency exchange offices in main cities;
no hotels, and no guys on the sidewalk with briefcases full of cash.
