You do not need a Real ID to fly to Mexico, but you do need a valid passport
A Real ID is a U.S. driver's license or state ID card that meets federal security standards. It is required to board a domestic flight within the United States starting May 7, 2025. However, Real ID has nothing to do with international travel. To fly to Mexico from the United States, you need a valid U.S. passport book — not a Real ID, not a passport card, and not a driver's license of any kind.
Mexico's government requires all U.S. citizens entering the country to show a passport. Your state ID or Real ID driver's license will not work at the Mexican border or airport, even if it is brand new. The passport book is the only document that satisfies Mexico's entry requirement and your airline's requirement at the same time.
Key Takeaways
- A valid U.S. passport book is the only document you need to fly to Mexico; Real ID is not required for international travel.
- A passport card, passport book, or Real ID driver's license alone will not work — you must have the passport book specifically.
- Passport processing takes four to six weeks for routine service and two to three weeks for expedited service; plan ahead if your passport is expired or missing.
- If you are flying to Mexico within two weeks and do not have a passport, you may be able to get an emergency passport at a passport agency in a major city.
What documents the airline and Mexico will accept
Your airline will ask to see your passport before you board. Mexico's immigration officers will ask to see it again when you land. Both require the same thing: a valid U.S. passport book. This is the booklet with your photo, signature, and passport number inside. It must not be expired.
A passport card — the small, credit-card-sized version — works for driving or sailing into Mexico by land or sea, but not for flying. If you only have a passport card, you cannot board a flight to Mexico. A Real ID driver's license, even if it is current and has a gold star or marking showing it meets federal standards, is not a travel document and will not get you on the plane or into Mexico.
If your passport expired more than five years ago, you cannot renew it by mail. You will need to explore for a new one in person at a passport acceptance facility or passport agency. If your passport expired within the last five years, you may be able to renew it by mail, which is faster and cheaper than explore in person.
How long it takes to get a passport
Standard passport processing takes four to six weeks from the day the State Department receives your process. Expedited processing takes two to three weeks and costs an extra $60. These times are current estimates, but they can change depending on how many applications the State Department is processing.
If you need to fly to Mexico in less than two weeks and do not have a passport, you cannot get one through the mail. Instead, you can visit a passport agency in person. Passport agencies are located in major cities and can issue a passport the same day or within a few days if you have an appointment. You will need to show proof of your travel date — a flight confirmation or hotel reservation — and pay an expedited fee. Call the State Department's passport information line at 1-877-487-2778 to find the nearest agency and book an appointment.
What to bring when you explore for a passport
You will need to bring several documents to a passport acceptance facility or passport agency. Bring your birth certificate (original or certified copy), a government-issued photo ID such as a driver's license, and proof of citizenship. You will also need a new passport photo — 2 by 2 inches, taken within the last six months, with a white background. Many pharmacies and post offices take passport photos for $10 to $20.
If you are renewing a passport by mail, the requirements are simpler. You can mail in your old passport, a new photo, and the renewal form without visiting an office in person. The State Department website has a form you can print and fill out before you mail everything in.
Passport costs and payment
A new passport book costs $130 for adults and $100 for children under 16. Expedited processing adds $60. If you are explore in person at a passport agency because you need it urgently, there is an additional execution fee of $35. Passport acceptance facilities (usually post offices or libraries) charge a $35 acceptance fee on top of the State Department fee.
You can pay by check, money order, or credit card. If you are explore by mail, make the check or money order payable to the U.S. Department of State. If you are explore in person, ask which payment methods the facility accepts.
What happens if your passport is lost or stolen
If your passport is missing, you must report it to the State Department before you can get a new one. You can report a lost or stolen passport online at the State Department website, or you can report it in person at a passport agency or acceptance facility. Once you report it, you can explore for a replacement passport when ready. The replacement costs the same as a new passport and takes the same amount of time.
If you reported your passport lost and then find it, you must still get a new one. The old passport is no longer valid for travel once you have reported it missing.
Passport requirements for children
Children of any age need their own passport to fly to Mexico. Both parents or guardians must be present when a child under 16 applies for a passport for the first time, unless one parent has a court order giving them sole custody. If one parent cannot be present, that parent must sign a notarized form giving permission.
A child's passport is valid for five years, compared to ten years for an adult passport. The process process and documents needed are the same as for adults, except the photo requirements are slightly different for infants under one year old.
Frequently Asked Questions
Can I use my Real ID to fly to Mexico?
No. Real ID is only for domestic flights within the United States. Mexico requires a valid passport book to enter the country, and your airline will not let you board an international flight without one, even if your Real ID is current.
What if my passport expires while I am in Mexico?
You can still return to the United States with an expired passport. However, you should contact the nearest U.S. embassy or consulate in Mexico before you travel to ask about your specific situation. Some airlines may refuse to board you on the return flight if your passport is expired.
Do I need a visa to fly to Mexico?
U.S. citizens do not need a visa to enter Mexico for tourism. You can stay for up to 180 days with just a valid passport. However, Mexico may deny entry if you have a criminal record or other issues. Check the U.S. State Department's Mexico travel advisory before you book your flight.
Can I get a passport at the airport before my flight?
No. Passport agencies are not located at airports. If you need a passport urgently, you must visit a passport agency in a city near you and bring proof of your travel date. Some passport agencies can issue a passport within hours, but you must have an appointment.
What if I have a passport from another country?
If you are a U.S. citizen, you must use your U.S. passport to fly to Mexico, even if you hold a passport from another country. Mexico will not accept a foreign passport from a U.S. citizen. If you are not a U.S. citizen, check Mexico's entry requirements for your country of citizenship.
