If you don't hold a driver's license issued in Armenia, then you'll likely need to apply for an International Driving Permit (IDP) in your place of residence to be allowed to rent a car. You should also be aware that if an IDP is required, it won't be valid on its own. You'll be asked to show your driver's license from your home country your passport and other forms of documentation as well. Lastly, it's important that the credit card used to book the rental matches the name on your driver's license and passport. A few other things to note to rent a car internationally are:

• Age restrictions: You'll need to be at least 25 in most places to rent a car. If you're younger, it may still be possible to rent a car but you'll have to pay a Young Driver's Surcharge. Additional restrictions may also apply to the types of cars you can rent.
• Driving limitations: Be sure to read the rules and regulations before driving away. Typically, you can't cross country borders, drive onto ferries or go off-roading with a rental car.
