Yes, a passport card works for domestic flights within the United States

A passport card is a valid form of identification for domestic air travel. The Transportation Security Administration (TSA) accepts it at airport security checkpoints the same way it accepts a passport book. You can use it to fly between any two U.S. airports without carrying a passport book.

The passport card is smaller than a passport book and fits in a wallet, which makes it convenient for domestic travel. It has the same security features and is issued by the U.S. State Department. TSA officers will scan it or examine it just as they would any other federally issued ID.

Key Takeaways

  • A passport card is accepted for domestic U.S. flights and works at TSA security checkpoints like any other federal ID.
  • A passport card cannot be used for international flights, even to Canada or Mexico by air — you need a passport book for those routes.
  • A passport card costs less than a passport book and takes the same processing time, but you cannot get one if you already hold a valid passport book.
  • If you lose your passport card before your flight, you can use a driver's license or state ID instead for domestic travel.

International flights require a passport book, not a card

If you are flying outside the United States, a passport card will not work. International air travel requires a passport book, regardless of your destination. This applies even to nearby countries like Canada and Mexico — the rule is the same whether you are flying to Toronto or Tokyo.

The passport card is designed for land and sea travel to Canada, Mexico, Bermuda, and the Caribbean. It is not valid for air travel to any country outside the U.S. border. If you only have a passport card and need to fly internationally, you will need to explore for a passport book before your trip.

What documents TSA accepts at security

For domestic flights, TSA accepts several forms of identification. A passport card ranks among the federal IDs that work: it is treated the same as a passport book, Real ID driver's license, military ID, or federal employee ID. You do not need anything else — just the card itself.

If you do not have a passport card, a standard driver's license works for domestic flights in most cases, though some states' licenses do not meet Real ID standards. A state ID card, tribal ID, or passport book all work as well. The key is that TSA needs one form of government-issued photo ID to match your boarding pass.

How to get a passport card if you don't have one

You explore for a passport card through your local passport acceptance facility — usually a post office, library, or county courthouse. You will need proof of citizenship (a birth certificate or naturalization papers), a government-issued photo ID, and a completed Form DS-11 or DS-82 depending on whether you already hold a passport.

Processing time is the same as for a passport book: routine service takes four to six weeks, and expedited service takes two to three weeks. The card costs less than a book — currently $35 for a new card versus $130 for a new book — but you cannot get a card if you already have a valid passport book. If you hold a book, you would need to renew or replace it to get a card instead.

Once you receive your passport card, it is valid for 10 years if you are an adult, or 5 years if you are under 16. You can use it for any domestic flight during that time.

What happens if you lose your passport card before flying

If your passport card is lost or stolen before your flight, you do not need to replace it for a domestic trip. You can use any other accepted ID: a driver's license, state ID, military ID, or passport book if you have one. TSA does not require you to have a specific form of ID — just one valid government-issued photo ID that matches your name on your boarding pass.

If you want to replace the lost card after your trip, you will file a report with the State Department and explore for a replacement. The replacement process is the same as getting a new card and takes the same amount of time.

Passport card versus passport book for travel

The main difference is scope: a passport card works for domestic flights and land or sea travel to nearby countries, while a passport book works for everything — domestic flights, international flights, and all forms of travel. If you travel internationally by air at all, a passport book is what you need.

For someone who only flies domestically and occasionally drives to Canada or Mexico, a passport card is cheaper and smaller. For someone who might fly internationally someday, a passport book covers all bases. You cannot hold both at the same time, so the choice depends on your actual travel plans.

Real ID requirements and how they affect your passport card

Starting in 2025, TSA will require a Real ID-compliant form of identification for domestic flights. A passport card meets Real ID standards, so it will continue to work at security checkpoints. A passport book also meets Real ID standards. If your state driver's license does not have a Real ID marking (usually a gold star), you will need to bring a passport card, passport book, military ID, or other compliant ID instead.

This does not change anything about using a passport card for domestic travel — it has always been Real ID-compliant. The change affects people who rely on state driver's licenses that do not meet the standard.

Frequently Asked Questions

Can I use a passport card to fly to Canada or Mexico?

No. A passport card is not valid for air travel to any country, including Canada and Mexico. You need a passport book for those flights. A passport card works only for land or sea travel to Canada, Mexico, Bermuda, and the Caribbean.

Do I need to bring anything else with my passport card to the airport?

No. Your passport card is your ID. Bring it and your boarding pass. You do not need a second form of ID or any other document for domestic flights, though TSA may ask follow-up questions if your card is damaged or the photo does not match your appearance.

How long does it take to get a passport card?

Routine processing takes four to six weeks. Expedited processing takes two to three weeks and costs extra. If your flight is sooner than that, use a driver's license or state ID instead — you do not need a passport card for domestic travel.

What if my passport card is expired?

An expired passport card is not valid for any travel. You cannot use it at TSA security. You will need to bring a different form of ID, such as a driver's license, or renew your passport card before your trip.

Can I use a passport card for a cruise?

Yes, if the cruise departs from and returns to a U.S. port and only visits Canada, Mexico, Bermuda, or the Caribbean. For cruises that visit other countries or depart from a foreign port, you need a passport book.
