How to Get an International Driver's License (IDP): What You Need to Know
If you're planning to drive abroad, you've likely come across the term International Driving Permit — often called an IDP or, informally, an "international driver's license." Understanding what it actually is, how it works, and how to get one can save you real trouble at a foreign border or rental car counter.
What an International Driving Permit Actually Is
An IDP is not a standalone license. It's a travel document — a standardized booklet that translates your existing domestic driver's license into multiple languages recognized by countries that have signed the 1949 Geneva Convention on Road Traffic or the 1968 Vienna Convention.
When you drive abroad, the IDP works alongside your valid U.S. driver's license. You carry both. The IDP translates your credentials so foreign officials, police, and rental agencies can verify your license without a language barrier. It does not replace your home license, and it has no legal standing without it.
Over 150 countries recognize IDPs in some form, though the specific treaty each country follows — Geneva or Vienna — affects which IDP format applies. Some countries honor either format; others are more specific. 🌍
Who Issues IDPs in the United States
In the U.S., only two organizations are authorized by the federal government to issue IDPs:
- AAA (American Automobile Association)
- AATA (American Automobile Touring Alliance)
No government agency — including the DMV — issues IDPs to U.S. residents. If you find a website claiming to sell "official" international driver's licenses from any other source, those documents are not recognized and are considered fraudulent by law enforcement in many countries.
What You Generally Need to Apply
The application process is straightforward and does not require a visit to a DMV office. While exact requirements can vary slightly between the two issuing organizations, the standard checklist typically includes:
| Requirement | Details |
|---|---|
| Valid U.S. driver's license | Must be current and valid at time of application |
| Minimum age | Generally 18 years old |
| Passport-style photos | Typically two recent photos required |
| Completed application form | Available through AAA or AATA |
| Fee payment | Fees vary by issuing organization; generally modest |
Some issuing organizations allow you to apply in person at a local branch, by mail, or online. The IDP is typically issued on the spot or within a short processing window.
How Long an IDP Is Valid
IDPs issued in the United States are generally valid for one year from the date of issue. They cannot be renewed — when one expires, you apply for a new one using the same process. The IDP's validity is also tied to your underlying domestic license: if your U.S. license is suspended or expires, the IDP becomes invalid regardless of its issue date.
What Countries Require or Recommend an IDP
Whether an IDP is legally required, strongly recommended, or entirely optional depends on the destination country and sometimes on how long you'll be driving there. Some countries:
- Require an IDP for all foreign drivers, no exceptions
- Require an IDP only if your domestic license isn't in their local language
- Strongly recommend an IDP even when not legally required, because rental agencies and police may request it
- Don't recognize IDPs at all and require a locally issued license for extended stays
Countries within the European Union, much of Southeast Asia, parts of Latin America, and many others commonly request IDPs. Japan, for example, has specific requirements that differ from standard IDP rules. Researching your destination country's specific entry and road laws before departure is essential — those rules sit entirely outside what any DMV or domestic licensing system controls.
IDPs for Foreign Drivers in the United States
The reverse situation also comes up: foreign visitors driving in the U.S. with an IDP issued by their home country. 🚗
Most U.S. states recognize foreign IDPs paired with a valid foreign license for short-term visitors. However, once a foreign national establishes residency in a U.S. state — the definition of which varies — they typically become subject to that state's driver's license requirements. At that point, many states require the person to obtain a domestic license within a specified period, often 30 to 90 days after establishing residency, though timelines and definitions vary significantly by state.
What an IDP Cannot Do
A few important boundaries worth understanding:
- An IDP cannot restore driving privileges that have been suspended or revoked in your home jurisdiction
- It does not authorize driving in your home country in place of a valid domestic license
- It cannot be used as a primary ID document for non-driving purposes like boarding domestic flights or accessing federal facilities
- It does not extend any grace period if your domestic license lapses
The Variables That Shape Your Specific Situation
Even though the IDP process is more standardized than most DMV procedures, several factors still determine exactly what applies to you:
- Your destination country — which treaty it follows, whether IDPs are legally required, and how long you can drive before needing a local license
- Your domestic license status — class, current validity, and whether any restrictions apply
- Your age — most IDP issuers require you to be at least 18, but some countries set their own minimum driving age for foreign visitors
- How long you'll be abroad — short-term tourism and long-term residency abroad are treated very differently by most countries
- Whether you're renting a vehicle — rental companies often have their own IDP policies independent of local law
How those factors combine in your particular case — destination, license type, length of stay, and purpose of travel — determines what documents you actually need in hand before you drive.
