What Is an International Driving Permit?
An International Driving Permit (IDP) is a standardized translation of your domestic driving license into multiple languages. It does not replace your regular license — instead, it supplements it, making it easier for car rental companies and local police to verify your credentials in countries where your home license may not be in the local language.
The IDP is recognized in over 150 countries under two international conventions: the 1949 Geneva Convention and the 1968 Vienna Convention. Which one you need depends on where you plan to drive.
Do You Actually Need One?
Whether you need an IDP depends on three factors: your home country, your destination, and the car rental provider's policy. Some countries legally require an IDP for all foreign drivers, while others only require it if your license is not in the Latin alphabet.
Even in countries where an IDP is not strictly mandatory, many car rental agencies require one as part of their terms and conditions. Showing up without one can mean the agency refuses to hand over the car — leaving you stranded at the airport with a non-refundable booking.
Countries Where an IDP Is Required by Law
Japan is the strictest example — you must have a 1949 Geneva Convention IDP specifically (not the 1968 Vienna Convention version). Other countries with strict IDP requirements include Thailand, Brazil, Vietnam, and several Middle Eastern nations. In these places, driving without an IDP is technically driving without a valid license, which can result in fines, vehicle impoundment, or voided insurance coverage.
Countries Where an IDP Is Recommended
Throughout most of Europe, an IDP is recommended but not always required for EU license holders. However, if your license is from outside the EU — particularly if it uses non-Latin characters (Chinese, Japanese, Arabic, Cyrillic) — an IDP becomes essential. Countries like Italy, Spain, Greece, and Turkey will frequently ask for one at rental desks and police checkpoints.
Countries Where You Probably Don't Need One
If you're driving within the EU with an EU license, or in a country that has a bilateral recognition agreement with your home country (like US drivers in Canada or UK drivers in Australia), an IDP is usually unnecessary. But carrying one never hurts — it costs very little and can prevent arguments at the rental desk.
How to Get an International Driving Permit
In most countries, IDPs are issued by national automobile associations. In the US, both AAA and AATA issue them. In the UK, it's the Post Office. In Australia, your state motoring club handles it. The process is typically straightforward: fill out a form, provide a passport photo and a copy of your license, and pay a small fee (usually $15–25 USD equivalent).
Processing time varies from same-day at a walk-in office to 2–4 weeks by mail. Apply well before your trip to avoid last-minute stress. The permit is valid for one year from the date of issue.

Buying from an unofficial source. The internet is full of websites selling "international driving permits" or "international driving licenses" that are not recognized by any government. Legitimate IDPs are only issued by government-authorized organizations (usually automobile associations). If a website promises instant PDF delivery of an IDP, it's almost certainly a scam.
Leaving your original license at home. An IDP is not a standalone document. You must carry your original domestic license alongside the IDP at all times. Without the original, the IDP is worthless.
Getting the wrong convention version. Japan specifically requires a 1949 Geneva Convention IDP. If your country only issues 1968 Vienna Convention IDPs (like Germany or France), you'll need to obtain a special Japanese translation of your license from JAF (Japan Automobile Federation) instead. Check which convention your destination recognizes before applying.
Assuming your IDP covers motorcycles or heavy vehicles. Your IDP covers only the vehicle categories listed on your domestic license. If your home license only authorizes cars, your IDP won't permit you to rent a motorcycle or campervan that requires a different license class.
IDP and Car Rental Insurance
Here's a critical detail many travelers overlook: if your destination country requires an IDP and you don't have one, your car rental insurance may be completely voided. This means that in the event of an accident, you could be personally liable for all damages — potentially tens of thousands of dollars.
Even third-party insurance policies and credit card coverage typically include clauses requiring the driver to hold all locally-required permits. Driving without a required IDP creates a gap in coverage that could be financially devastating.

Bottom Line
An IDP costs less than a single day of car rental and takes minimal effort to obtain. Given that it can prevent refused rentals, police fines, and voided insurance, there's almost no reason not to get one if you're planning to drive abroad. Apply through your country's official automobile association at least 4 weeks before your trip, and always carry it alongside your original domestic license.
