If you don't possess a driver's license issued in Northern Mariana Islands, then you'll likely need to apply for an International Driving Permit (IDP) in your home country in order 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 current driver's license your passport and other forms of ID as well. Lastly, make sure the credit card used to book the rental matches the name on your license and passport. Some additional requirements to rent a car internationally are:

• Age restrictions: You need to be 25 or older in many countries to rent a car. If you're younger than that, it might still be possible to rent a car but you'll have to pay a Young Driver's Surcharge. Additional restrictions may also apply to what kinds of cars you can rent.
• Driving limitations: Be sure to read the fine print before driving away. Usually, you can't cross country borders, drive onto ferries or off road with your rental car.
