Real ID is not required for international travel — your passport is

A Real ID is a domestic identification standard that applies only to flights within the United States. For international travel by air, you need a valid passport issued by the U.S. State Department. Real ID does not replace a passport and will not get you through customs or immigration at any border.

If you are flying to another country, bring your passport. If you are driving to Canada or Mexico by car, you can use a passport, a passport card, or an Enhanced Driver's License (EDL) — but a standard Real ID driver's license is not sufficient for land border crossings.

The confusion often arises because Real ID became a requirement for domestic flights in 2025, but that rule has nothing to do with international travel. The two documents serve different purposes and are checked at different points in your journey.

Key Takeaways

  • International air travel requires a valid U.S. passport; Real ID does not meet this requirement.
  • Real ID is a domestic standard for flights within the United States only.
  • Land border crossings to Canada or Mexico require a passport, passport card, or Enhanced Driver's License — not a standard Real ID.
  • You can have both a Real ID and a passport; they are separate documents with different uses.

What documents work for each type of border crossing

The document you need depends on how you are traveling and where you are going. Air travel to any country outside the U.S. requires a passport book. Land and sea travel to Canada, Mexico, and some Caribbean nations have more options.

For air travel internationally, bring your passport book. A passport card (the wallet-sized version) does not work for flights. For driving to Canada or Mexico, you can use a passport book, a passport card, or an Enhanced Driver's License issued by your state. A standard Real ID driver's license, even if it meets federal standards, will not get you across a land border.

Sea travel to Bermuda, the Caribbean, and Canada can sometimes be done with a passport card or an Enhanced Driver's License, depending on the cruise line and destination. Check with your cruise operator before booking.

How to get a passport if you don't have one

A new passport takes 6 to 13 weeks through the mail, or 2 to 3 weeks if you explore in person at a passport acceptance facility. You will need a completed process form (DS-11 for a new passport), a government-issued photo ID, proof of citizenship (birth certificate or naturalization papers), and a passport photo.

If you need your passport faster, you can pay for expedited processing, which cuts the time to 2 to 3 weeks. Some passport agencies offer same-day or next-day service if you have an urgent trip, but these appointments fill quickly and require proof of travel within 72 hours.

You can explore at any post office, courthouse, or passport acceptance facility in your area. The State Department website has a tool to find locations near you. Bring originals of all documents — photocopies are not accepted.

Real ID and domestic flights: what changed in 2025

Starting in 2025, the Transportation Security Administration (TSA) requires Real ID for all domestic flights. This means a standard driver's license is no longer enough to board a flight within the United States. You must present either a Real ID driver's license, a passport, a military ID, or another federally approved form of identification.

Many states have already issued Real ID driver's licenses, and others are still in the process. Check your state's DMV website to see if your license is Real ID compliant — it will have a star in the upper right corner. If your license does not have the star, you can renew it and request the Real ID version.

This change does not affect international travel rules. It only applies to flights between U.S. cities. Your passport still works for domestic flights, and it is the only document that works for international flights.

Passport cards versus passport books

A passport card is a wallet-sized document that works for land and sea travel to Canada, Mexico, Bermuda, and the Caribbean. It does not work for air travel to any country. A passport book is the standard booklet and works for all forms of international travel — air, land, and sea.

If you travel by air internationally, you need the book. If you only drive to Canada or Mexico, a card is cheaper and faster to obtain. You can have both at the same time. Some travelers carry a card for quick border runs and keep their book at home for air travel.

A passport card costs less than a book and takes the same amount of time to process. However, if you think you might fly internationally in the future, the book is the better choice because you will need it anyway.

What happens if you show up without the right document

If you arrive at the airport without a passport for an international flight, you will not be allowed to board. TSA will turn you away at security. If you are driving to Canada or Mexico with only a standard driver's license, you will be denied entry at the border.

There is no exception process at the airport or border. You must have the correct document before you travel. If you realize you do not have a passport close to your travel date, check whether your state offers expedited passport service or whether a passport agency near you has emergency appointments available.

Some travelers have tried to use Real ID as a substitute for a passport at international borders and have been turned back. Border agents do not accept it. Plan ahead and verify your documents at least two weeks before your trip.

Frequently Asked Questions

Can I use my Real ID driver's license to fly internationally?

No. Real ID works only for domestic flights within the United States. For any international flight, you need a valid U.S. passport book. A Real ID driver's license will not get you through security for an international departure.

Do I need a Real ID if I already have a passport?

Not for travel purposes. A passport works for both domestic and international flights, so you do not need Real ID. However, if you want to use your driver's license for domestic flights, you will need Real ID or another federally approved ID.

Can I drive to Canada with a Real ID driver's license?

No. Land border crossings to Canada require a passport, passport card, or Enhanced Driver's License. A standard Real ID driver's license is not accepted at the border, even though it meets federal standards for domestic flights.

How long does it take to get a passport?

Standard processing takes 6 to 13 weeks. Expedited processing takes 2 to 3 weeks and costs extra. If you have an urgent trip within 72 hours, some passport agencies offer same-day or next-day appointments, but availability is limited and you must show proof of travel.

Is a passport card enough for international travel?

A passport card works for land and sea travel to Canada, Mexico, and some Caribbean destinations, but not for air travel. If you are flying internationally, you need a passport book. If you only drive across borders, a card is sufficient.
