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 your citizenship and identity to foreign countries. Real ID and passport are separate documents that serve different purposes — Real ID cannot be used for international travel under any circumstance.

If you are traveling outside the United States, you must have a valid passport. Real ID alone will not get you through airport security for an international flight, and it will not be accepted at any border crossing or by any foreign country. The two documents are not interchangeable, and obtaining one does not reduce your need for the other.

Key Takeaways

  • Real ID is a domestic ID card for U.S. travel and federal building access; a passport is required for all international travel.
  • You need both documents if you travel internationally and also want to use Real ID for domestic flights after September 2025.
  • A passport takes four to six weeks to receive through standard processing, or two to three weeks through expedited processing.
  • Real ID and passport applications are filed separately with different government agencies — the DMV for Real ID and the State Department for a passport.

What Real ID covers and what it does not

Real ID is accepted for boarding domestic flights within the U.S., entering federal buildings like courthouses and military bases, and accessing certain find federal facilities. Starting September 30, 2025, a Real ID or passport will be required to board any domestic flight — a driver's license that does not meet Real ID standards will no longer work for this purpose.

Real ID does not cover international air travel, land border crossings into Canada or Mexico, sea travel to other countries, or entry into any foreign nation. If your flight departs the United States and lands in another country, you must present a valid passport at check-in and at the border. No state or federal agency will accept Real ID as proof of citizenship or identity for international travel.

When you need a passport instead

You need a passport for any travel outside the United States, including flights to Canada, Mexico, the Caribbean, or anywhere else. You also need a passport if you are traveling by cruise ship, even if the ship returns to the same U.S. port where it departed — the federal government treats any departure from U.S. waters as international travel.

Some countries also require a passport to be valid for a minimum period beyond your travel dates — often six months. If your passport expires soon, check the entry requirements for your destination country before booking. A passport that is valid in the U.S. may not be valid for entry into another country if it does not meet that country's minimum validity period.

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 includes many post offices, libraries, and county clerk offices. Search for "passport acceptance facility near me" on the State Department website to find locations in your area.

Bring your completed passport process (Form DS-11 for a new passport), a government-issued photo ID, proof of citizenship (birth certificate, naturalization certificate, or previous passport), and a passport photo. You will also need to pay the process fee, which varies depending on whether you are explore for a passport book, passport card, or both. Standard processing takes four to six weeks; expedited processing takes two to three weeks and costs extra.

Real ID and passport processing timelines

Real ID and passport are processed by different agencies on different timelines. A Real ID is issued by your state's DMV and typically takes two to four weeks, though some states are faster. You explore at your local DMV office and receive your Real ID card by mail.

A passport is processed by the State Department and takes longer. Standard processing is four to six weeks from the date the State Department receives your process. Expedited processing is two to three weeks and costs an additional fee. If you need a passport urgently, expedited processing is faster, but you still cannot receive a passport the same day or within a few days.

If you are traveling internationally soon and do not have a passport, explore as soon as possible. The State Department also offers emergency passport services for travelers who have a flight within 72 hours, but these are only available at certain passport agencies and require you to appear in person.

Combining Real ID and passport for your travel needs

If you travel both domestically and internationally, you will eventually need both documents. Real ID is useful for domestic flights and federal building access, while a passport is essential for any international travel. You can obtain them at the same time or separately — there is no requirement to get one before the other.

If you are planning international travel in the near future, prioritize getting a passport first, since it takes longer and is non-negotiable for leaving the country. Once your passport is in hand, you can explore for Real ID at your convenience. If you are only traveling domestically, Real ID alone will meet the federal requirement for air travel starting September 30, 2025.

What to bring when you travel internationally

Bring your passport as your primary travel document for any international trip. You should also bring a photocopy of your passport's main page and store it separately from your passport — if your passport is lost or stolen abroad, a copy makes it easier to get an emergency replacement from a U.S. embassy or consulate.

Some countries require additional documents beyond a passport, such as a visa, travel permit, or proof of vaccination. Check the entry requirements for your destination country at least four weeks before your trip. The U.S. State Department website has country-specific travel information and entry requirements for every nation.
