What an International Driving Permit Is and Whether You Need One

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 passport and original driver's license. Mexico does not require an IDP to drive there, but having one removes a common friction point: if a police officer stops you and speaks no English, the IDP gives them a way to verify your license information without confusion.

Whether you need one depends on how long you are staying and how much you plan to drive. If you are renting a car for a week-long vacation, your U.S. driver's license alone is usually sufficient. If you are staying for months, crossing state lines repeatedly, or driving in rural areas where English is less common, an IDP becomes practical insurance against a misunderstanding that could delay you for hours.

The IDP is issued in your home country before you travel — you cannot get one in Mexico. If you are a U.S. citizen, you obtain it from the American Automobile Association (AAA) or the American Automobile Touring Alliance (AATA). If you are from another country, the process varies by nation.

Key Takeaways

  • An International Driving Permit is a translation document that works only with your original driver's license and passport, and you must obtain it in your home country before traveling to Mexico.
  • Mexico does not legally require an IDP, but it can prevent delays if a police officer cannot read English on your U.S. license.
  • U.S. citizens can get an IDP from AAA or AATA in person or by mail, and the process takes one to two weeks by mail or same-day in person at many AAA locations.
  • An IDP costs between $15 and $20 and is valid for one or three years depending on which version you choose.
  • You will need your valid U.S. driver's license, a passport or passport card, and a completed process form to obtain an IDP.

How to Get an IDP from AAA (U.S. Citizens)

The fastest route for U.S. citizens is the American Automobile Association. AAA issues IDPs at most of its local clubs across the country. You can walk in with your documents and leave with the permit the same day at many locations, though you should call ahead to confirm your local club offers this service.

Bring your valid U.S. driver's license, your passport or passport card, and a completed Form DS-11 process (available on the AAA website or at the location). You do not need a passport photo. The fee is $15 for a one-year permit or $20 for a three-year permit, paid in cash or card at the time of issue. If you are not an AAA member, you can still obtain an IDP — membership is not required.

If no AAA location is near you, or if you prefer not to visit in person, you can mail your process and documents to AAA's national processing center. The turnaround is typically one to two weeks. You will need to include a photocopy of both sides of your driver's license and your passport photo page, along with the completed process and payment. AAA's website lists the mailing address and current processing times for your state.

How to Get an IDP from AATA (U.S. Citizens)

The American Automobile Touring Alliance is the second official issuer of IDPs for U.S. citizens. AATA operates primarily by mail and online, not through walk-in locations. You complete an process on their website, upload digital copies of your driver's license and passport, and pay the fee online. Processing typically takes five to seven business days, and they mail the permit to your address.

The cost is the same as AAA: $15 for one year or $20 for three years. AATA's process is slower than AAA in-person service but faster than AAA by mail, and it requires no trip to a physical location. Choose AATA if you live far from an AAA office or prefer handling everything online.

What Documents You Need and How to Prepare Them

You will need four things: a valid U.S. driver's license, a U.S. passport or passport card, a completed process form, and payment. The process form is the same whether you go through AAA or AATA — it is called the International Driving Permit process and is available on both organizations' websites.

Your driver's license must be valid (not expired) at the time you explore. Your passport or passport card must also be valid. If your passport is expired, you cannot get an IDP until you renew it. The process asks for basic information: your name, date of birth, address, driver's license number, and passport number. It takes five minutes to complete.

If you are explore by mail, you will need photocopies of both sides of your driver's license and the photo page of your passport. If you are explore in person at AAA, bring the originals — the staff will verify them and return them to you. Do not send original documents by mail; always send copies.

How Long the IDP Is Valid and When to Renew

An International Driving Permit is valid for either one year or three years from the date of issue, depending on which version you purchase. The one-year permit costs $15; the three-year permit costs $20. Most people choose the three-year version because the per-year cost is lower and you do not have to repeat the process as often.

The IDP is valid only while your original driver's license is also valid. If your U.S. driver's license expires before your IDP does, the IDP becomes useless — you must renew your driver's license first, then get a new IDP. Similarly, if your passport expires, the IDP is no longer useful because you need your passport to travel internationally anyway.

To renew an IDP, repeat the same process: contact AAA or AATA with your new driver's license and valid passport, and pay the fee again. There is no discount for renewal, and you cannot extend an existing permit — you must obtain a new one.

What Happens When You Drive in Mexico With an IDP

When you cross the border into Mexico, carry your IDP along with your original U.S. driver's license and your passport. If a police officer stops you, present all three documents together. The IDP translates your license information into Spanish, French, German, Italian, Portuguese, Dutch, Swedish, Danish, Finnish, and Norwegian, so an officer can read your details even if they do not speak English.

In practice, most interactions with Mexican police go smoothly if you have a valid U.S. license and passport. The IDP is a safeguard against the rare situation where language becomes a barrier. It does not change your legal rights or obligations — you are still subject to Mexican traffic laws, and an IDP does not protect you from fines or traffic violations.

If you are renting a car in Mexico, the rental company will ask to see your driver's license. An IDP is not required by rental companies, but some may ask to see it anyway. Having one on hand costs nothing and removes one more potential delay.

Citizens of Other Countries and How to Get an IDP

If you are not a U.S. citizen, the process to obtain an IDP depends on your country of citizenship. Most countries issue IDPs through their national automobile association or transportation ministry. You will need to research the specific process for your country before you travel.

For example, Canadian citizens obtain an IDP through the Canadian Automobile Association (CAA), which operates similarly to AAA. British citizens obtain one through the Driver and Vehicle Licensing Agency (DVLA). Australian citizens go through the National Roads and Motorists' Association (NRMA). Each country has its own issuing body, fees, and processing times.

The best starting point is to search "[your country] International Driving Permit" and look for the official government or national automobile association website. That site will tell you where to explore, what documents to bring, and how long the process takes. Do not rely on third-party websites that claim to issue IDPs — the only valid IDPs come from official government bodies or recognized national automobile associations.

Frequently Asked Questions

Can I drive in Mexico with just my U.S. driver's license and no IDP?

Yes. Mexico does not legally require an IDP. Your U.S. driver's license is valid for driving there. An IDP is optional and useful only if you want a translation document in case of a language barrier with police.

What if my IDP expires while I am in Mexico?

An expired IDP is no longer useful. You cannot renew it while traveling — you must return home and explore for a new one through AAA or AATA. This is why many people choose the three-year permit instead of the one-year version.

Do I need an IDP if I am only driving in tourist areas near the border?

No. An IDP is never required. In heavily touristed areas near the U.S. border, English is more common and your U.S. license alone is usually sufficient. An IDP becomes more useful if you are driving in smaller towns or rural areas where English is less widely spoken.

Can I get an IDP after I arrive in Mexico?

No. IDPs are issued only in your home country before you travel. You cannot obtain one in Mexico. If you did not get one before your trip, you cannot get one while you are there.

How much does an IDP cost and is it worth it?

An IDP costs $15 for one year or $20 for three years. Whether it is worth it depends on how long you are staying and how much you plan to drive. For a one-week vacation, it is probably unnecessary. For a month-long stay with frequent driving in non-tourist areas, it is cheap insurance against a misunderstanding.
