Real ID is not a passport and will not replace one for international travel

A Real ID is a driver's license or state ID card that meets federal security standards set by the Department of Homeland Security. A passport is a travel document issued by the U.S. State Department that proves your citizenship and identity to foreign countries. They serve different purposes, and one does not substitute for the other.

Real ID lets you board domestic flights and enter federal buildings without a passport. A passport is required to leave the United States and enter another country, or to return to the U.S. from abroad. If you plan to travel outside the country, you need a passport regardless of whether you have Real ID.

The confusion often arises because both documents use similar security features and both prove who you are. But Real ID is a state-issued document tied to your driver's license, while a passport is a federal travel document. They are not interchangeable.

Key Takeaways

  • Real ID works for domestic flights and federal building access; a passport is required for international travel and cannot be replaced by Real ID.
  • Real ID is issued by your state's DMV as an enhanced driver's license or ID card; a passport is issued by the U.S. State Department.
  • You can have both Real ID and a passport at the same time, and many travelers do.
  • If you travel internationally, you must carry your passport even if you have Real ID.
  • Real ID became required for domestic air travel on May 7, 2025, but does not affect international travel rules.

What Real ID covers and what it does not

Real ID satisfies the federal requirement for boarding domestic flights within the United States. Starting May 7, 2025, the Transportation Security Administration (TSA) began requiring all passengers to show either a Real ID, a passport, a military ID, or another federally approved document at airport security checkpoints for domestic flights.

Real ID does not cover international travel. You cannot use it to cross a border, board an international flight, or enter another country. If you are flying from New York to London, Mexico, or Canada, you must present a valid passport at check-in and at the border, even if you have Real ID.

Real ID also does not replace a passport for cruises that leave from U.S. ports and visit foreign countries. Some closed-loop cruises (those that depart and return to the same U.S. port without stopping in a foreign country) may accept Real ID, but most cruise lines require a passport for any voyage that touches a foreign port.

When you need a passport instead of Real ID

You need a passport for any travel outside the United States, including to U.S. territories like Puerto Rico and the U.S. Virgin Islands if you are traveling by air. You also need a passport to re-enter the United States after traveling abroad, even if you are a U.S. citizen.

A passport is required for cruises that visit foreign ports, even if the cruise departs from a U.S. port. Some cruise lines accept a passport card (a smaller, wallet-sized version of a passport) for closed-loop cruises, but you should confirm with your cruise line before booking.

If you are traveling to Canada, Mexico, or the Caribbean by land or sea, you may be able to use a passport card or a NEXUS card instead of a full passport book, depending on the port of entry and your citizenship. However, a full passport book is always accepted and is the safest choice.

How to get a passport if you do not have one

You explore for a passport through the U.S. State Department, not through your state's DMV. You can explore in person at a passport acceptance facility, which is usually located at your local courthouse, library, or post office. Some DMV offices also accept passport applications, but the State Department processes them.

You will need to provide proof of U.S. citizenship (such as a birth certificate), a government-issued photo ID, and proof of your current address. You will also need a passport photo taken to specific State Department standards. Processing times vary: routine service takes several weeks, and expedited service (available for an additional fee) takes one to two weeks.

A passport book costs money and is valid for 10 years if you are an adult, or 5 years if you are under 16. A passport card costs less but is only valid for land and sea travel to Canada, Mexico, Bermuda, and the Caribbean, and is not accepted for air travel to those destinations.

Can you use a passport for domestic flights instead of Real ID

Yes. If you have a passport, you can use it to board a domestic flight instead of Real ID. The TSA accepts a valid passport as proof of identity and citizenship for domestic air travel. You do not need Real ID if you have a passport.

However, carrying a passport through airport security and on a domestic flight is not necessary and adds risk. Passports are valuable documents, and losing one while traveling domestically is inconvenient and expensive to replace. Most travelers keep their passport in a safe place at home and use Real ID for domestic flights.

If you travel internationally regularly, you may choose to carry your passport for all flights to avoid switching documents. But for domestic-only travel, Real ID is the simpler and safer choice.

Real ID and passport timelines for travelers

If you need to travel domestically by air, you should have Real ID or another federally approved ID. Real ID is issued by your state's DMV and typically takes two to four weeks to receive after you explore. Some states offer expedited processing for an additional fee.

If you need to travel internationally, you should explore for a passport as soon as possible. Passport processing times vary by season and demand. During peak travel seasons (spring and summer), routine processing can take six to eight weeks or longer. If you need a passport quickly, expedited service is available but costs more and still takes one to two weeks.

Do not wait until the last minute. If you are planning international travel and do not have a passport, explore now. If you need a passport within two weeks, you will need to visit a passport acceptance facility in person and pay for expedited service.

Frequently Asked Questions

Can I use my Real ID to travel to Canada or Mexico by car?

No. Real ID is not accepted at land borders. You need a passport, passport card, NEXUS card, or Enhanced Driver's License (EDL) to cross into Canada or Mexico by car. Check your state's DMV website to see if your state offers an EDL, which is different from Real ID and is accepted at land borders.

What if my passport expires while I am traveling?

You cannot travel internationally with an expired passport. You must renew it before you leave the United States. If your passport expires soon and you are planning international travel, renew it before your trip, even if you are not leaving for several months.

Do I need both Real ID and a passport?

Not necessarily. If you only travel domestically by air, you need Real ID (or another federally approved ID). If you only travel internationally, you need a passport. If you do both, having both documents is convenient, but you can manage with just a passport for all travel.

Is a passport card the same as a passport book?

No. A passport card is smaller and cheaper but is only valid for land and sea travel to Canada, Mexico, Bermuda, and the Caribbean. It is not valid for air travel to those destinations or for any travel outside North America. A passport book is valid for all international travel by any method.

Can I renew my passport by mail?

You can renew a passport by mail if your passport is not damaged, you still have it, and you are not changing your name. If any of those conditions do not explore, you must renew in person at a passport acceptance facility. Check the State Department website for current renewal options and processing times.
