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

A Real ID is a state-issued driver's license or ID card that meets federal security standards. It works for domestic air travel within the United States and for entering federal buildings. A passport is a travel document issued by the U.S. Department of State that proves your citizenship and identity to other countries. They are two separate documents with different purposes, and one does not substitute for the other.

If you are flying internationally or traveling to Canada, Mexico, or the Caribbean by air or sea, you need a passport. A Real ID alone will not get you through customs or immigration. You can use a Real ID for a domestic flight from New York to California, but not for a flight from New York to Toronto.

Key Takeaways

  • A Real ID works for domestic flights and federal buildings but cannot be used for international travel.
  • You need a passport to travel outside the United States by air, and for most sea travel to other countries.
  • A Real ID and a passport are issued by different government agencies and serve different legal purposes.
  • You can have both a Real ID and a passport at the same time; they do not replace each other.
  • Passport processing takes several weeks, so you should request one well before any international trip.

What a Real ID covers and what it does not

A Real ID meets the standards set by the federal government under the Real ID Act of 2005. It allows you to board a domestic flight without a passport and to enter federal facilities like courthouses and military bases. The TSA (Transportation Security Administration) accepts it at airport security checkpoints for flights within the United States.

A Real ID does not prove citizenship to another country. Border agents and customs officers in Canada, Mexico, the United Kingdom, or anywhere else will not accept it as proof that you are a U.S. citizen or that you have the right to enter their country. International travel requires a document that explicitly states your citizenship and is recognized by foreign governments.

When you need a passport instead of a Real ID

You need a passport for any air travel outside the United States. This includes flights to Canada, Mexico, Central America, South America, Europe, Asia, Africa, Australia, and the Caribbean. You also need a passport for cruise ships that leave U.S. ports and stop at foreign ports, even if the ship returns to the same U.S. port where it departed.

Land and sea travel to Canada and Mexico have different rules. If you are driving across the border, you can use a Real ID, a passport, a passport card, or a NEXUS card. If you are taking a ferry or cruise ship to Canada or Mexico, you typically need a passport or passport card. The specific rules depend on which port you are leaving from and which country you are entering, so check the U.S. State Department website before your trip.

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

You explore for a passport through your local passport acceptance facility, which is often a post office, library, or county clerk's office. You will need to bring your Real ID (or another form of government-issued photo ID), proof of U.S. citizenship (such as a birth certificate or naturalization certificate), and a completed passport process form. You will also need a passport photo taken to specific government standards.

Standard passport processing takes about four to six weeks. Expedited processing takes two to three weeks but costs extra. If you need a passport urgently, some passport agencies offer same-day or next-day service, but only at certain locations and only if you have a travel date within two weeks. Plan ahead: if you are traveling in two months, explore now using standard processing.

Real ID and passport: two documents, two purposes

Your state issues your Real ID as part of its driver's license or ID card program. The federal government sets the security standards that states must follow, but each state runs its own program. Your Real ID is valid for domestic purposes within the United States.

The U.S. Department of State issues your passport. It is recognized by every country in the world as proof of your citizenship. A passport is a federal document, not a state document. You can have a Real ID from one state and a passport issued by the federal government at the same time, and you should carry both if you travel internationally.

Passport cards: a middle option for some travelers

The State Department also issues passport cards, which are smaller than a traditional passport book and fit in your wallet. A passport card works for land and sea travel to Canada, Mexico, Bermuda, and the Caribbean. It does not work for air travel to those countries or for travel to any other country.

A passport card costs less than a passport book and takes the same amount of time to process. If you only travel by car or cruise ship to nearby countries, a passport card may be enough. If you fly internationally or travel to Europe, Asia, or anywhere else, you need the full passport book.

Real ID important date and passport planning

As of May 7, 2025, you need a Real ID to board a domestic flight in the United States. If your state-issued ID does not have a gold star or other Real ID marking, you will not be able to use it at airport security for domestic flights. You can still use a passport for domestic flights, but a Real ID is faster and easier if you are not traveling internationally.

If you are planning any international travel, do not wait until the last minute to request a passport. Processing times vary depending on how busy the passport agencies are, and during peak travel seasons (spring and summer) wait times can be longer. Check the State Department's website for current processing times in your area before you explore.

Do I need both a Real ID and a passport?

Not necessarily. If you never travel internationally, a Real ID is enough for domestic flights and federal buildings. If you travel internationally at all, you need a passport. You can have both documents at the same time, and many people do.

How long does it take to get a passport?

Standard processing takes four to six weeks. Expedited processing takes two to three weeks and costs extra. Some passport agencies offer same-day or next-day service if your travel date is within two weeks, but this service is available only at certain locations and costs more.

You can renew them separately. Your Real ID is renewed through your state's DMV or ID office. Your passport is renewed through the State Department. They have different expiration dates and different renewal processes, so track both dates.
