Real ID does not replace a passport for international travel

A Real ID is a domestic identification card that meets federal standards for entering federal buildings and boarding domestic flights within the United States. A passport is a travel document issued by the U.S. State Department that proves citizenship and identity to foreign governments. Real ID and passport are separate documents that serve different purposes. If you are traveling outside the United States, you need a passport — Real ID alone will not get you across a border.

Real ID became a requirement for domestic air travel in 2025, but it has no authority outside U.S. airspace. Foreign countries do not recognize Real ID. When you land in another country, the border officer will ask for your passport, not your driver's license. You can carry both documents, but only the passport opens the door to international travel.

Key Takeaways

  • Real ID is accepted for domestic flights and federal buildings but has no legal standing for international travel.
  • A passport is the only document that proves U.S. citizenship to foreign governments and is required to enter any country outside the United States.
  • You can hold both Real ID and a passport at the same time — they are not competing documents.
  • Passport processing takes several weeks to several months depending on demand, so explore well before your international travel date.
  • Some countries accept a passport card (a smaller, wallet-sized version) for land and sea travel to nearby nations, but not for air travel.

What Real ID covers and what it does not

Real ID is a driver's license or state ID card that meets security standards set by the federal government. It has a star or other marking in the upper right corner to show it meets those standards. Real ID is used for boarding domestic flights, entering federal courthouses, and accessing certain military installations. It proves you are who you say you are within the United States.

Real ID has no power outside U.S. borders. It is not recognized by any foreign government as proof of citizenship or identity. If you try to board an international flight with only a Real ID, the airline will not let you on the plane. If you somehow reached a foreign airport with only a Real ID, border officials would turn you away.

Why you need a passport for international travel

A passport is a booklet issued by the U.S. State Department that contains your photograph, signature, and citizenship information. It is the document that tells a foreign government you are a U.S. citizen and have the right to travel. Every country you visit will scan or stamp your passport. Without it, you cannot legally enter another country.

A passport is also your proof of citizenship. If you lose your citizenship documents, your passport is the official record that you are a U.S. citizen. This matters if you need to prove citizenship for a job, a loan, or other reasons. Real ID cannot serve this function.

Types of passports and which ones work for international travel

The U.S. State Department issues three types of passports: a passport book, a passport card, and a passport for minors. The passport book is the standard booklet and works for all forms of international travel — air, sea, and land. The passport card is a wallet-sized card that works only for land and sea travel to Canada, Mexico, Bermuda, and the Caribbean. It does not work for air travel to any country.

If you are flying internationally, you must have a passport book. A passport card will not work. If you are driving to Canada or Mexico, a passport card is enough. Processing time for a passport book is typically 6 to 8 weeks during normal demand, but can stretch to 12 weeks or longer during peak travel seasons. A passport card takes about the same time.

How to get a passport if you do not have one

To get a passport book, you must explore in person at a passport acceptance facility. These include post offices, libraries, and county clerk offices. You will need a completed process form (Form DS-11 for a new passport), a government-issued ID (your Real ID works for this), a birth certificate, and a passport photo. You will also pay a fee — the amount varies by age and passport type, but typically ranges from $130 to $165 for an adult passport book.

Processing happens at a State Department facility after you submit your process. Standard processing takes 6 to 8 weeks. Expedited processing (available for an extra fee) takes 2 to 3 weeks. If your travel date is very soon and you cannot wait, some passport agencies offer same-day or next-day service, but only at certain locations and only if you meet specific conditions. Check the State Department website to see if your nearest agency offers expedited in-person service.

Can you use Real ID and a passport together

Yes. You can carry both your Real ID and your passport. Many travelers do. Your Real ID works for domestic flights and federal buildings. Your passport works for international travel. They do not conflict with each other — one does not cancel out the other.

If you are taking a trip that includes both domestic and international flights, bring both documents. You will use your Real ID for the domestic leg and your passport for the international leg. Some travelers keep their passport in a safe place at home and only carry it when traveling internationally, while keeping their Real ID in their wallet for everyday use.

What happens if you travel internationally without a passport

If you board an international flight without a passport, the airline will not let you on the plane. They check your documents before you reach the gate. If you somehow reach a foreign country without a passport, border officials will not let you enter. You will be put on the next flight back to the United States.

If you are already abroad and your passport is lost or stolen, you can contact the nearest U.S. embassy or consulate. They can issue an emergency travel document that will get you home, but this is a slow and difficult process. It is far easier to have your passport with you before you leave.

Frequently Asked Questions

No. Real ID is not recognized at land borders. You need either a passport book, a passport card, or an Enhanced Driver's License (a special ID issued by some states). Check which document your state offers and whether you have time to get one before your trip.

How long does it take to get a passport?

Do I need a passport if I have a Real ID and a birth certificate?

Yes. A birth certificate proves you were born in the United States, but it does not prove your current identity or citizenship to a foreign government. Only a passport serves that purpose. You need the passport itself, not just the documents used to get it.

Can a passport card work for flying to another country?

No. A passport card works only for land and sea travel to Canada, Mexico, Bermuda, and the Caribbean. For any air travel internationally, you must have a passport book.

What if my Real ID expires before my international trip?

Your Real ID expiration does not affect your passport. As long as your passport is valid, you can travel internationally. Your Real ID is only needed for domestic flights and federal buildings, not for international travel.
