Your passport works at airport security, but Real ID is becoming the standard for domestic flights

Yes, you can use your passport instead of a Real ID to get through airport security for domestic flights. The Transportation Security Administration (TSA) accepts a valid U.S. passport as proof of identity. However, starting May 7, 2025, you will need either a Real ID-compliant driver's license, a passport, or another approved document to board a domestic flight — a regular driver's license alone will no longer work.

The key difference: a passport proves citizenship and identity, which is all TSA requires. Real ID is a security standard for state-issued IDs that adds extra verification steps when you get the card. Both get you through security, but they serve slightly different purposes. If you already have a valid passport, you do not need to get a Real ID just for flying domestically.

Key Takeaways

  • A valid U.S. passport is accepted at airport security for domestic flights and counts as Real ID-compliant identification.
  • Starting May 7, 2025, you must present either a Real ID driver's license, passport, passport card, or other approved document — a standard driver's license is no longer sufficient.
  • You do not need to obtain a Real ID if you have a current passport, since the passport satisfies the federal requirement.
  • Passport cards (the wallet-sized version) also meet Real ID requirements for domestic air travel.
  • International travel still requires a full passport book; a Real ID driver's license alone is not sufficient to leave the country.

What documents the TSA accepts at security checkpoints

The TSA maintains a list of documents that satisfy the Real ID requirement for domestic flights. A valid U.S. passport book is at the top of that list. So is a U.S. passport card — the smaller, wallet-sized version issued by the State Department. Both are federal documents, which is why they work regardless of your state's Real ID status.

Other accepted documents include a Real ID-compliant driver's license or state ID card (marked with a gold star or star outline, depending on your state), a military ID, a trusted traveler card (like Global Entry or TSA PreCheck), a permanent resident card, and a U.S. Enhanced Driver's License. If you hold any of these, you meet the requirement. A passport is straightforward one option among several.

Why your passport might be easier than getting Real ID

Getting a Real ID requires a trip to your state's DMV with original documents — typically a birth certificate, proof of residency, and your current ID. The process varies by state, and some DMVs have long wait times. If you already have a passport, you have already completed similar verification, and the passport is valid for 10 years (or 5 years if you are under 16).

A passport card lasts the same 10 years and costs less than a full passport book, though it is only valid for land and sea travel to Canada, Mexico, Bermuda, and the Caribbean — not international air travel. For domestic flights alone, either the passport book or card works. If you travel internationally by air, you need the full passport book.

The difference between a passport and Real ID for travel

A passport is a travel document issued by the federal government that proves citizenship. Real ID is a security standard that applies to state-issued driver's licenses and ID cards. The two are not the same thing, but they overlap in what they accomplish at airport security.

When you explore for Real ID, your state verifies your identity and citizenship using documents you provide, then issues a driver's license or ID card marked as Real ID-compliant. A passport goes through a similar verification process at the federal level. Both prove you are who you say you are, which is what TSA needs to let you board a domestic flight. The passport straightforward does it through a different agency.

What happens if you only have a standard driver's license after May 7, 2025

If your driver's license does not have a Real ID marker (usually a gold star in the upper right corner), you will not be able to board a domestic flight using only that license after May 7, 2025. TSA will turn you away at the checkpoint. You will need to present a passport, passport card, military ID, or another approved document instead.

This does not mean your old license becomes invalid for driving or other purposes — it straightforward will not work for federal facilities like airports. If you do not have a passport and do not want to get one, you will need to explore for a Real ID driver's license at your state's DMV. If you already have a passport, you have nothing to do.

How to check if your driver's license is already Real ID-compliant

Look at your driver's license. If there is a gold star, a star outline, or a marking that says "Real ID" in the upper right corner, your license is compliant. The exact appearance varies by state — some use a star, others use a different symbol — but your state's DMV website will show you what to look for.

If you are unsure, contact your state's DMV directly or visit their website. You can also bring your passport to the airport; TSA will accept it regardless of what your license says. The simplest way to know you are covered is to have either a current passport or a Real ID-marked license in your wallet.

Passport cards versus passport books for flying

Both versions are valid for domestic flights. A passport card is smaller, cheaper, and easier to carry. A passport book is larger but necessary if you fly internationally. If you only fly domestically and want to keep your travel document wallet-sized, a passport card is sufficient. If you ever fly internationally, you need the book.

The card costs less to obtain and renew, but it is only valid for land and sea travel to nearby countries. The book costs more but works everywhere. Neither one expires faster than the other — both last 10 years for adults. Choose based on where you actually travel, not on which one works at the airport, since both do.

Frequently Asked Questions

Do I need to renew my passport before May 7, 2025?

No. As long as your passport is currently valid, it works at airport security after May 7, 2025. You do not need to renew it early. If your passport is expired, you will need to renew it before you can use it to board a flight, but that is true whether or not the Real ID important date has passed.

Can I use an expired passport at the airport?

No. TSA requires a valid, unexpired document. An expired passport will not work, even if it was valid before May 7, 2025. Check your passport's expiration date before you go to the airport. If it is expired, you will need to renew it or bring a different approved document.

What if I have a passport but it is at home and I forgot it?

TSA will not let you board without an approved document. If you forgot your passport and your driver's license is not Real ID-compliant, you cannot fly that day. Always bring your passport or Real ID with you when you travel. Some airports have Real ID information desks, but they cannot issue documents on the spot.

Is a passport card valid for international flights?

No. A passport card is only valid for land and sea travel to Canada, Mexico, Bermuda, and the Caribbean. For any international flight, you need a full passport book. If you travel internationally by air, do not rely on a passport card alone.

Can I use my passport instead of Real ID for other federal buildings?

Yes. A passport is accepted at federal facilities that require Real ID, including some government offices and military bases. However, Real ID is primarily designed for airport security and federal building access. Check with the specific facility about what documents they accept.
