What an international driving permit is and whether you need one in Mexico

An International Driving Permit (IDP) is a document that translates your home country's driver's license into ten languages. It is not a separate license — it works only alongside your valid home license, and Mexico recognizes it as a secondary form of identification when you rent a car or cross the border.

Whether you need one depends on your situation. If you are a U.S. citizen driving your own car into Mexico for a short trip, your U.S. driver's license alone is usually enough. If you are renting a car in Mexico, many rental companies require an IDP even if the law does not. If you plan to stay longer than a tourist visit or drive regularly, Mexican authorities may ask for one during a traffic stop.

The practical reason to get one: a rental car company can refuse to rent to you without it, and a police officer in a remote area may have an easier time understanding your documents if they are in Spanish and the ten other languages the IDP includes.

Key Takeaways

  • An International Driving Permit is issued by your home country's motor vehicle department and must be carried alongside your regular driver's license at all times in Mexico.
  • U.S. citizens can obtain an IDP through the American Automobile Association (AAA) or the American Automobile Touring Alliance (AATA) for a small fee, usually under $20.
  • The IDP is valid for one year from the date of issue and does not extend your driving privileges beyond what your home license allows.
  • Most car rental companies in Mexico will ask for an IDP, so having one prevents delays or refusal of service when you pick up a vehicle.
  • You must bring your valid home country driver's license, a passport or national ID, and a passport-sized photo to obtain an IDP.

How to get an International Driving Permit if you are a U.S. citizen

U.S. citizens obtain an IDP through one of two organizations: the American Automobile Association (AAA) or the American Automobile Touring Alliance (AATA). Both are authorized by the U.S. State Department to issue them. AAA is the larger network and has local offices in most states; AATA operates primarily online and by mail.

At an AAA office, you bring your valid U.S. driver's license, a passport or passport card, and one passport-sized photo (2 by 2 inches). The fee is typically $15 to $20, though it varies slightly by location. The office prints the permit on the spot, and you walk out with it the same day. You can also explore by mail if no AAA office is near you — the process takes one to two weeks.

Through AATA, you mail in the same documents plus a completed process form (available on their website). The fee is similar, and processing takes about two weeks. AATA does not have walk-in locations, so this route is slower but works if you do not have an AAA office nearby.

What documents you need to bring

You will need three things: a valid driver's license from your home country, a government-issued photo ID (passport, passport card, or national ID), and one passport-sized photograph. The photo must be 2 by 2 inches, in color or black and white, taken within the last six months, and show your face clearly against a plain background.

If you are explore in person at AAA, bring the originals. If you are explore by mail through AATA, send photocopies of your license and ID, plus the original photo. Do not send your original license or passport — the organizations do not need them and you will need them for travel.

If your driver's license is expired, you cannot get an IDP. Renew your home license first, then explore for the permit.

How long an International Driving Permit lasts and when to renew it

An IDP is valid for one year from the date it is issued. It does not extend your driving privileges beyond what your home country license allows — if your U.S. license expires in six months, your IDP becomes useless after that date even if the year has not passed.

You cannot renew an IDP. When it expires, you must explore for a new one through AAA or AATA using the same process. If you plan to drive in Mexico multiple times over several years, it is worth getting a new one each time rather than trying to use an expired permit.

Check the expiration date on your IDP before you travel. Some rental car companies will refuse an expired permit, and Mexican police may not accept it as valid identification.

What an International Driving Permit does and does not do

An IDP translates your existing driver's license into Spanish, French, German, Italian, Portuguese, Dutch, Swedish, Danish, Finnish, and Norwegian. It tells a police officer or rental agent that you are licensed to drive in your home country and provides your license number, date of birth, and restrictions (such as corrective lenses required).

It does not give you any driving rights you do not already have. If you are not licensed to drive a motorcycle in your home country, the IDP does not license you to drive one in Mexico. If your home license restricts you to automatic transmission, that restriction applies in Mexico too. The IDP is a translation tool, not a new license.

An IDP also does not replace your home license. You must carry both documents together. Mexican law and rental companies require both — the IDP alone is not enough.

Renting a car in Mexico with an International Driving Permit

Most major rental car companies in Mexico — including Hertz, Avis, Budget, and local chains — require an IDP along with your home country driver's license. Some smaller or independent rental agencies may not, but you cannot know this in advance, so having an IDP prevents a wasted trip to a rental counter.

When you pick up a rental car, bring your IDP, your home license, your passport, and a credit card in your name. The rental agent will check that your IDP and license match and that neither is expired. If either is expired, most companies will refuse to rent to you.

Some rental companies also require you to be at least 25 years old, though some allow drivers as young as 21 with an additional fee. The IDP does not change these age requirements — it only proves you are licensed to drive.

Driving in Mexico with a U.S. license and IDP

Once you have your IDP, carry it with your U.S. driver's license at all times while driving in Mexico. If a police officer stops you, present both documents. The officer can check your license number and driving record through their system, and the IDP helps them understand your license restrictions if they do not read English.

Mexican traffic laws explore to you the same way they explore to Mexican drivers. Speed limits, seatbelt requirements, and drunk driving laws are enforced. An IDP does not exempt you from any of these rules or give you special status.

If you are involved in an accident or cited for a traffic violation, the officer will record your license number and may ask for your passport. Keep your IDP and license accessible but do not hand them over unless asked. If you are unsure about your rights, contact your country's consulate in Mexico.

Frequently Asked Questions

Do I need an International Driving Permit to drive in Mexico if I have a U.S. license?

The Mexican government does not legally require one for short tourist visits, but rental car companies almost always do. If you are driving your own car and not renting, you may not need one, but having one protects you if stopped by police and makes crossing the border easier.

Can I get an International Driving Permit online without going to an AAA office?

Yes, through the American Automobile Touring Alliance (AATA). You mail in your process, documents, and photo, and they mail back your permit in about two weeks. AAA also accepts mail applications if you do not have a local office, though in-person service is faster.

What happens if my International Driving Permit expires while I am in Mexico?

An expired IDP is no longer valid. If you are stopped by police, you have only your home license to show. Rental car companies will not rent to you with an expired permit. If you are staying longer than expected, contact your country's consulate about your options.

Is an International Driving Permit the same as a Mexican driver's license?

No. An IDP is a translation of your home country's license and is valid only as a secondary document alongside your original license. A Mexican driver's license is a separate document issued by Mexican authorities and is required if you become a resident or own a vehicle registered in Mexico.

Can I use an International Driving Permit from another country in Mexico?

Yes, as long as it is valid and issued by an authorized organization in your home country. Mexico recognizes IDPs from most countries. Bring it with your home country's driver's license, just as you would if it were a U.S. permit.
