No, a Real ID cannot replace a passport 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. It works for domestic flights within the United States and entry to federal buildings. A passport is a separate document issued by the U.S. State Department that proves your citizenship and identity to foreign countries. They are two different documents with different purposes, and you need a passport to leave the country or enter another one.

If you are planning to travel outside the United States — by air, sea, or land — you must carry a valid passport. A Real ID alone will not get you through customs or immigration at any border. Even if you are traveling to Canada or Mexico by car, you need either a passport, a passport card, or a NEXUS card (a trusted traveler program). A Real ID cannot substitute for any of these.

Key Takeaways

  • A Real ID is a domestic document for flights within the U.S. and federal building access; a passport is required for all international travel.
  • You need a passport book or passport card to cross any U.S. border, whether by plane, car, or boat.
  • A Real ID and a passport serve different purposes and are issued by different government agencies.
  • If you have a Real ID but no passport, you must obtain a passport before traveling internationally.
  • Some travelers use a passport card instead of a passport book for land and sea travel to Canada, Mexico, and the Caribbean.

What a Real ID actually covers

A Real ID is accepted as identification for domestic airplane flights and entry to federal facilities like military bases, nuclear power plants, and some government offices. Starting in May 2025, the Transportation Security Administration (TSA) requires a Real ID or another federally accepted form of ID to board a domestic flight. This means you can use a Real ID instead of a passport for a flight from New York to California, but not for a flight from New York to Toronto.

The Real ID standard was created after the September 11 attacks to may support that state-issued IDs meet consistent security requirements across all states. Each state's Real ID looks different, but they all have a gold or metallic star in the upper right corner. If your driver's license or state ID has this star, it is a Real ID. If it does not, you can still fly domestically using a passport, passport card, military ID, or other federally accepted document.

What a passport covers

A passport is the document you need to prove your U.S. citizenship and identity when you cross an international border. It is issued by the U.S. State Department, not by your state. There are two main types: a passport book (the traditional blue booklet) and a passport card (a wallet-sized card). Both prove citizenship, but they have different rules about where you can use them.

A passport book is accepted everywhere — for flights, cruises, land border crossings, and entry to any country. A passport card is smaller and cheaper, but it is only valid for land and sea travel to Canada, Mexico, Bermuda, and the Caribbean. You cannot use a passport card for international flights. If you are flying internationally, you must have a passport book.

How to get a passport if you only have a Real ID

If you need to travel internationally and only have a Real ID, you must obtain a passport before your trip. You can explore for a passport book or passport card through your local passport acceptance facility. These are usually located at post offices, libraries, county clerk offices, or state government buildings. You will need to bring your Real ID (or another form of identification), proof of citizenship such as a birth certificate, and a completed passport process form.

Processing times vary depending on demand and the time of year. Standard processing usually takes several weeks to a few months. If you need a passport quickly, you can request expedited processing for an additional fee, which typically reduces the wait to one to two weeks. Some passport agencies also offer same-day or next-day service if you explore in person at a passport agency office in a major city, though this requires an appointment and an additional fee.

When you might need both documents

You might carry both a Real ID and a passport if you travel frequently for both domestic and international trips. Your Real ID serves as your primary identification for domestic flights and federal building access. Your passport is necessary only when you cross an international border. Some travelers keep their passport at home in a safe place and only bring it when traveling internationally, using their Real ID for domestic trips.

If you are a frequent international traveler, you may also want to consider a passport card in addition to your passport book. The card is useful for quick trips to nearby countries by car or boat and is easier to carry than a full passport book. However, it does not replace the passport book for flights.

Other documents that work for international travel

If you do not have a passport, there are a few other documents that work for specific types of international travel. A passport card works for land and sea travel to Canada, Mexico, Bermuda, and the Caribbean. A NEXUS card, SENTRI card, or FAST card are trusted traveler programs that allow expedited border crossing and can be used as travel documents for land and sea borders. A military ID can be used for some travel to military installations abroad. None of these replace a passport book for international flights.

Frequently Asked Questions

Can I use my Real ID to fly to Canada?

No. A Real ID is not accepted for international flights. You need a passport book, passport card, NEXUS card, or enhanced driver's license to travel to Canada. If you are driving or taking a cruise, a passport card works. If you are flying, you must have a passport book.

What if my passport is expired but I have a Real ID?

An expired passport is not valid for international travel, and a Real ID cannot replace it. You will need to renew your passport before traveling internationally. Renewal is faster than a new process and can often be done by mail if your passport is not too old and was issued when you were an adult.

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

No. A passport book is accepted for domestic flights, so you do not need a Real ID if you have a passport. However, a Real ID is convenient for domestic travel because it is smaller and easier to carry than a passport book. Many people get a Real ID for everyday use and keep their passport for international trips.

Can I use my Real ID at the airport for an international flight if I also have my passport?

No. At the airport, you must show your passport to the airline and to customs and immigration for any international flight, regardless of whether you also have a Real ID. The airline will not accept a Real ID alone for international travel.

How much does a passport cost compared to a Real ID?

A Real ID costs the same as a regular driver's license or state ID in your state, which varies by state but is typically $20 to $50. A passport book costs $130 for adults (or $100 if you are renewing), and a passport card costs $35 (or $20 if renewing). Expedited processing adds an extra fee.
