Yes, you can fly domestically with a driver's license, but it must be a Real ID-compliant license or you'll need a backup document

A standard driver's license works for domestic flights within the United States. The Transportation Security Administration (TSA) accepts it at airport security checkpoints. However, the license must be either a Real ID-compliant license (marked with a gold star or other state-specific indicator) or issued after your state began enforcing Real ID requirements. If your license is older and not Real ID-compliant, you can still fly—but you'll need to bring a second form of identification, such as a passport, passport card, military ID, or permanent resident card.

International flights are different. A driver's license alone is never enough to leave the country. You must have a valid passport, and depending on your destination, you may also need a visa. A driver's license can serve as a secondary form of ID at the airport, but it cannot replace a passport for international travel.

Key Takeaways

  • A Real ID-compliant driver's license is accepted for domestic flights and is the only ID you need at TSA security.
  • If your license is not Real ID-compliant, bring a second form of ID such as a passport, military ID, or permanent resident card.
  • International flights require a valid passport; a driver's license cannot substitute for one under any circumstance.
  • Check your state's DMV website to confirm whether your current license is Real ID-compliant, as the marking varies by state.

What Real ID compliance means and how to check your license

Real ID is a federal security standard that went into effect in 2020. States began issuing Real ID-compliant licenses gradually, and enforcement at airport security became mandatory in May 2025. A Real ID-compliant license has a visible marker—usually a gold star, but some states use a circle, a flag, or another symbol. Check the front or back of your license for this marking.

If you're unsure whether your license is compliant, visit your state's Department of Motor Vehicles (DMV) website and search for "Real ID." Most state DMV sites have a page explaining which licenses are compliant and how to upgrade if yours is not. You can also ask at the airport security checkpoint; TSA officers can tell you when ready whether your license meets the standard.

Upgrading to a Real ID-compliant license usually requires an in-person visit to your DMV, proof of citizenship or legal residency, and proof of your current address. The process and cost vary by state—some states charge a small fee, others do not. Most upgrades are processed within a few weeks.

What to bring if your license is not Real ID-compliant

If your driver's license does not have the Real ID marking, you have two options: upgrade your license, or bring a second form of identification to the airport. The second form must be an official government-issued ID. Acceptable documents include a U.S. passport, passport card, military ID, permanent resident card (green card), tribal ID, or enhanced driver's license.

You do not need both documents to be in perfect condition, but they must be valid and not expired. TSA officers will check both IDs at the security checkpoint. Bring them both in your carry-on bag, not checked luggage, so you have them when you reach security.

International flights and passport requirements

A driver's license has no value for international travel. Every country requires visitors to present a valid passport at immigration control. Some destinations also require a visa, which is a separate document issued by the country's embassy or consulate. A few countries allow U.S. citizens to enter without a visa under specific conditions (such as the Schengen Area in Europe for stays under 90 days), but a passport is always mandatory.

If you do not have a passport, you must obtain one before you can book an international flight. U.S. passports are issued by the State Department. You can explore in person at a passport acceptance facility (often a post office, library, or courthouse) or renew by mail if your passport is not expired and meets other conditions. Processing times vary—standard service takes several weeks, and expedited service costs more but is faster.

What happens at TSA security if your ID is questioned

TSA officers are trained to recognize Real ID-compliant licenses and other acceptable forms of ID. If you arrive at security with a non-compliant license and no backup ID, the officer will tell you that you cannot proceed through the checkpoint. You will not be allowed to board your flight that day.

If this happens, you have a few options: return home to retrieve a passport or other acceptable ID, visit a nearby DMV to explore for a Real ID upgrade (though this will not be processed in time for your flight), or rebook your flight for a later date when you have the correct documentation. Some airlines allow you to change your flight date without a fee if you miss your flight due to ID issues, but policies vary—contact your airline directly.

To avoid this situation, check your license before you book your flight. If it is not Real ID-compliant and you do not have a passport, either upgrade your license or plan to bring a second form of ID.

Real ID requirements by state

Real ID compliance is a federal standard, but each state decides how to mark compliant licenses and what documents are required to obtain one. All 50 states now issue Real ID-compliant licenses, but the timeline for issuing them and the appearance of the marking differ.

Some states automatically upgraded existing licenses to Real ID status; others require you to visit the DMV and request an upgrade. A few states issue both compliant and non-compliant licenses depending on what you request. The safest approach is to check your state's DMV website directly and look for the Real ID marking on your current license. If you do not see it, contact your DMV or visit in person to upgrade.

Frequently Asked Questions

Can I fly if my driver's license is expired?

No. TSA requires a valid, non-expired form of ID. An expired driver's license will not work, even if it is Real ID-compliant. If your license is expired, renew it at your DMV before your flight. If you have a valid passport, you can use that instead.

What if I lost my driver's license and only have a passport?

A passport is a valid form of ID for domestic flights. You do not need a driver's license if you have a passport. Bring your passport to the airport, and TSA will accept it at security.

Do I need a Real ID license if I have a military ID?

No. Military ID is an acceptable form of identification for TSA security on its own. You do not need a Real ID-compliant driver's license if you have a valid military ID.

Can I use a passport card instead of a full passport for international flights?

A passport card is valid for international travel by land or sea to Canada, Mexico, Bermuda, and the Caribbean. However, for air travel to most international destinations, you need a full passport book, not a card. Check your destination's entry requirements before you travel.

What if my state hasn't issued me a Real ID license yet?

All states now issue Real ID-compliant licenses. If you have not received one, visit your state's DMV website to learn how to request an upgrade, or bring a second form of ID (such as a passport) to the airport along with your current driver's license.
