There is a very specific kind of travel frustration that tends to happen at the worst possible moment:
When you’re told you’re missing a document you’ve never heard of. Ugh.
Don’t let that be an International Driving Permit. It is a small detail, but it can completely derail your plans if you don’t have it when you need it.
What Is an International Driving Permit?
An International Driving Permit (IDP) is not a driver’s license.
It’s a translation of your valid U.S. driver’s license into multiple languages, designed to be understood by local authorities and rental agencies worldwide.
You must carry it alongside your physical U.S. or territorial license. On its own, it has no legal validity. It includes:
- Your name and photo
- Your driver information
- Translations in 10 languages
Do You Actually Need an International Driving Permit?
Short answer: sometimes yes, often no, but in most cases it’s worth having.
There are a lot of rumors out there about whether you do or don’t need an IDP. In places like Italy, it is officially required, though enforcement can be inconsistent and rental desks do not always check. This is what leads to the confusion and the idea that an IDP isn’t really necessary.
It’s always my policy to err on the side of caution and take the easy extra step to get the IDP and be prepared just in case it’s needed. This does not need to be the thing that ruins my vacation.
What happens in practice
An IDP is one of those “you may not need it, but you might wish you had it” items.
It is not always asked for at the rental car counter, even in places where it is technically required. Many travelers rent cars without ever being asked to show one. Where it becomes more relevant is:
- If you are pulled over by local authorities
- If you are involved in an accident
- If you encounter a stricter-than-typical rental agent or company policy
In these cases, not having an IDP can become an issue.
This is also where having the right travel insurance becomes important. It’s invaluable if you’re driving internationally and something unexpected happens.
You should likely get an IDP if:
- You are planning to drive any vehicle abroad
- You are renting a car abroad, especially if you will be driving it outside major cities
You may not strictly need it, but should still consider it if:
- You are traveling to countries like France or Portugal, where U.S. licenses are often accepted for short stays
- You want to avoid complications if something unexpected happens
- You prefer to remove variables from your trip (yes, we do)
You can likely skip it if:
- You are not planning to drive at all
- You are relying entirely on private transfers, trains, or guided transport
A practical rule:
If there is any chance you will drive internationally, it is usually worth getting one. It is a small, easy step that can go a long way toward protecting you if something goes wrong.

How to Get an International Driving Permit
In the United States, IDPs are issued by AAA (American Automobile Association) and the American Automobile Touring Alliance. Most travelers use AAA. (Hi, me)
There is typically no appointment required, but it’s worth calling ahead to confirm your local AAA branch offers IDP services and check their hours. (I found out the hard way that AAA offices keep very strange hours)
You do have to be at least 18 years old to obtain an IDP.
Step-by-Step
Step 1: Download the application
Complete and print the IDP application form from AAA.
Step 2: Get passport photos
You will need two physical 2″ x 2″ passport photos. This does not have to be the same photo that is on your actual passport. You can get these taken at drugstores like CVS, post offices, UPS stores, and some AAA offices can take these for you.
Step 3: Gather your documents
- Valid U.S. or territorial driver’s license
- Completed application
- Two physical 2″ x 2″ passport photos
- $20 Payment
Step 4: Apply in person or by mail
Applying in person is the fastest option. Typically your IDP is issued the same day.
Instructions for mailing in an application can be found on the application.
Important Rules to Know Before You Go
- You must carry your IDP together with your U.S. driver’s license. It is not a substitute for a license.
- An IDP is typically valid for one year
- An IDP cannot be issued more than six months before your trip
- An IDP must be issued in the United States
If you are already overseas, you cannot obtain an IDP locally. You can apply by mail through a U.S. office, but processing and return shipping can take several weeks.
FAQ: International Driving Permit
Will the rental car company ask for an IDP?
Sometimes, but not always.
Many travelers are never asked for it at the rental counter, even in places where it is technically required. That said, policies vary by company and agent.
Where it matters more is if you are stopped by local authorities or involved in an accident. That is when having an IDP can become important. Better safe than sorry.
Can I get an IDP after I leave the U.S.?
Not in person. And not quickly. It must be issued by a U.S.-authorized organization. You can apply by mail while abroad, just note that it can take several weeks to process and ship if applied for while already abroad.
Is an International Driving Permit required everywhere?
No. Some countries require it, others recommend it, and in many cases rental companies may still ask for it even if local law does not.
What happens if I don’t have one?
You may be denied a rental car or encounter issues with local authorities, including possible fines depending on the country.
Can I use it instead of my driver’s license?
No. It must always be used alongside your valid U.S. or territorial license.
How long is it valid?
One year from the date of issue.
How far in advance should I get it?
Within six months of your travel date, but at least a week or two before you travel, just in case there are any issues at the AAA office.
Final Thought
The International Driving Permit is not a glamorous part of travel prep, but it’s one of the easiest ways to avoid unnecessary complications.
You may never be asked for it. But if you are, having it turns a potentially stressful moment into a simple one.
If your trip involves renting a car or moving between destinations, having the logistics handled in advance makes a noticeable difference. I’m always happy to help make that part feel seamless.
