Dinar is the only legal tender in Serbia. Exchange offices are ubiquitous in major cities, and they routinely accept euros, U.S. dollars and pounds sterling. If exchanging U.S. dollars, you might be required to present a valid form of ID and the procedure may take longer as note serial numbers are recorded. There are no such formalities when exchanging other currencies. Officially aepproved exchange offices display licenses with the seal of the National Bank of Serbia. Banks also perform currency exchange, but almost always at less favorable exchange rates than small exchange offices. Either way, there is no commission charged. There are also exchange machines which can be found at the airport and in major shopping malls. The exchange rate can fluctuate in excess of 1% from one day to the other, but in overall, major fluctuations do not occur over short periods of time.
