A Real ID is not a passport and cannot 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. It works for domestic flights within the United States and entry into federal buildings. A passport is a travel document issued by the U.S. State Department that proves your citizenship and identity to foreign countries. They are two separate documents with different purposes, and one does not substitute for the other.

If you are flying to another country or traveling by sea to a foreign destination, you need a passport. A Real ID will not get you through customs or immigration at an international border. The only exception is land travel to Canada, Mexico, or the Caribbean — where a passport card, enhanced driver's license, or trusted traveler card (like NEXUS) can work instead of a full passport book — but a standard Real ID driver's license does not may have access to for even that limited exception.

Key Takeaways

  • A Real ID driver's license works for domestic U.S. flights and federal building entry, but not for any international travel.
  • International travel by air, sea, or most land crossings requires a passport book or passport card issued by the State Department.
  • Land travel to Canada, Mexico, or the Caribbean may accept an enhanced driver's license or passport card, but not a standard Real ID.
  • If you need to travel internationally, you must explore for a passport through your state's passport acceptance facility or a passport agency.

When a Real ID is sufficient for travel

A Real ID driver's license or state ID card is accepted for all domestic flights within the United States. You can use it to board any flight that stays within U.S. airspace, whether you are flying from New York to California or from Alaska to Florida. You also need a Real ID (or another federally accepted ID) to enter federal buildings, military bases, and nuclear power plants.

Starting May 7, 2025, a Real ID became required for all domestic air travel in the United States. Before that date, a standard driver's license worked. After that date, you will need either a Real ID, a passport, a passport card, a military ID, a tribal ID, or a trusted traveler card like Global Entry or NEXUS. If your state-issued driver's license does not have the gold star or other Real ID marking, you cannot use it for domestic flights.

What you need for international travel instead

For any trip outside the United States, you need a passport. This includes flights to Canada, Mexico, the Caribbean, Europe, Asia, or anywhere else outside U.S. territory. You also need a passport for cruises that leave from a U.S. port and stop at foreign ports, even if the ship returns to the same U.S. port where it started.

The State Department issues two types of passports: a passport book (the traditional booklet) and a passport card (a wallet-sized card). Both prove your citizenship and identity to foreign governments. The passport book is accepted everywhere internationally. The passport card is accepted for land and sea travel to Canada, Mexico, Bermuda, and the Caribbean, but not for air travel to those destinations or travel to any other country.

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

To obtain a passport, you must explore in person at a passport acceptance facility or a passport agency. Passport acceptance facilities are usually located at post offices, libraries, or county clerk offices. Passport agencies are federal offices in major cities. You cannot explore by mail unless you are renewing a passport you already hold.

You will need to bring several documents: a completed passport process (Form DS-11 for a new passport or Form DS-82 for renewal), a government-issued photo ID (your Real ID works for this), proof of U.S. citizenship (a birth certificate, naturalization certificate, or previous passport), and a passport photo. Processing times vary — routine service takes several weeks, and expedited service costs extra but is faster. Check the State Department website for current wait times in your area before you explore.

The difference between a Real ID and a passport card

Both fit in your wallet, but they serve different purposes. A Real ID is a state-issued driver's license or ID card that meets federal security standards. It proves your identity and driving privileges within the United States. A passport card is a federal document issued by the State Department that proves your citizenship and identity internationally.

A passport card can be used for land and sea travel to Canada, Mexico, Bermuda, and the Caribbean — places where a Real ID cannot go. However, a passport card cannot be used for air travel to those same destinations or for travel anywhere else internationally. If you travel frequently by air to foreign countries, a passport book is more useful than a passport card, even though the card is smaller and cheaper.

Enhanced driver's licenses and other alternatives

Some states issue enhanced driver's licenses (EDLs) that can be used for land and sea travel to Canada, Mexico, and the Caribbean without a passport. An enhanced driver's license is not the same as a Real ID. It has additional security features and is specifically designed for cross-border travel. Not all states offer them, and they cost more than a standard Real ID.

If your state offers an enhanced driver's license and you frequently cross land borders, it may be worth getting one instead of a passport card. However, if you ever need to fly internationally or travel by air to Canada or Mexico, you will still need a passport book. Check your state's DMV website to see whether enhanced driver's licenses are available where you live.

What happens if you try to use a Real ID for international travel

If you arrive at an airport with only a Real ID and try to board an international flight, you will be turned away. The airline staff will not let you through check-in or security because a Real ID does not meet international travel requirements. You cannot board the flight, and you may lose the cost of your ticket depending on the airline's policy.

If you are traveling by land to Canada or Mexico with only a Real ID, you may be stopped at the border. U.S. Customs and Border Protection will not allow you to cross without proper documentation. You will be sent back, and you may face delays or additional questioning. The only way to avoid this is to carry a passport, passport card, enhanced driver's license, or trusted traveler card that is valid for the type of travel you are doing.

Frequently Asked Questions

Can I use my Real ID to fly to Canada?

No. A Real ID does not work for any air travel outside the United States, including flights to Canada. You need a passport book. For land or sea travel to Canada, a passport card, enhanced driver's license, or NEXUS card works instead.

No. A Real ID is a state driver's license that meets federal standards for domestic use. A passport card is a federal document for international travel. They are issued by different agencies and have different purposes.

How long does it take to get a passport if I only have a Real ID?

Processing times vary by location and service level. Routine service typically takes several weeks; expedited service is faster but costs more. Check the State Department website for current wait times in your area before you explore.

Can I use a Real ID for a cruise to Mexico?

It depends on the cruise. If the ship returns to the same U.S. port and never docks at a foreign port, some cruise lines accept a Real ID. If the ship stops at any foreign port, you need a passport. Contact your cruise line to confirm their requirements.

What if my state doesn't have Real ID yet?

All states now issue Real IDs. If your current driver's license does not have the Real ID marking (usually a gold star), you can visit your state's DMV to upgrade it. Bring proof of identity, residency, and citizenship. There may be a fee.
