A regular driver's license works for domestic flights, but not international ones

You can board a domestic flight within the United States using a standard driver's license as your ID. The Transportation Security Administration (TSA) accepts it at airport security checkpoints. However, if you're flying internationally—to Canada, Mexico, the Caribbean, or anywhere outside U.S. borders—a regular driver's license is not sufficient. You'll need a passport, passport card, or one of a few other federally approved travel documents.

The distinction matters because TSA rules for domestic travel differ from the requirements set by U.S. Customs and Border Protection (CBP) for leaving and re-entering the country. A domestic flight only requires proof of identity and citizenship status; an international flight requires proof that you have permission to cross a border.

Key Takeaways

  • A regular driver's license satisfies TSA requirements for domestic U.S. flights and is one of the most common forms of ID used at security checkpoints.
  • International flights require a passport, passport card, enhanced driver's license, or NEXUS/SENTRI card—a regular driver's license will not work.
  • Your driver's license must be current and not expired; TSA will not accept an expired license even for domestic travel.
  • If your license was issued by a state that does not meet federal Real ID standards, you may face additional screening on domestic flights after May 2025.

What TSA accepts for domestic flights

TSA maintains a list of acceptable forms of ID for domestic air travel. A valid driver's license from any U.S. state or territory appears on that list. The license must not be expired—TSA checks the expiration date printed on the card. If your license expired yesterday, it will not work, even if you've already renewed it and are waiting for the new card to arrive.

Other documents that work at TSA checkpoints include a passport, passport card, military ID, tribal ID, or a state ID card (the non-driver version). You need only one form of acceptable ID. If you're traveling with children under 18, they do not need ID on domestic flights if they're traveling with an adult, though some airlines have their own policies worth checking before you arrive at the airport.

Real ID compliance and what it means for your license

Starting May 7, 2025, TSA will enforce Real ID standards for all domestic flights. This is a federal security standard that most states have already met, but a handful have not. If your driver's license was issued by a state that does not comply with Real ID requirements, you will still be allowed to fly domestically—but you may face additional screening at the security checkpoint.

To know whether your state's license meets Real ID standards, check the TSA website or look at your license itself. Real ID-compliant licenses typically display a star or other marking in the upper right corner. If your license does not have this marking and your state has not met the standard, you have two options: obtain a Real ID-compliant license from your state's DMV, or bring a second form of ID (such as a passport) to the airport. Either approach will allow you to pass through security without delay.

International travel requires a passport or equivalent document

A regular driver's license will not get you past U.S. Customs and Border Protection when you leave the country or return to it. For flights to Canada, Mexico, or any other destination outside the U.S., you must carry a passport book or passport card. These are issued by the U.S. State Department and prove both your citizenship and your identity to foreign governments.

A few alternatives exist if you don't have a passport. An enhanced driver's license (available in some states) includes security features that allow entry to Canada and Mexico by land or sea, though not by air. A NEXUS card or SENTRI card (trusted traveler programs) also works for some land crossings but not for air travel. For flights, a passport is the standard requirement. If you're planning an international trip and don't have a passport, explore at your local passport acceptance facility—processing times range from several weeks to several months depending on demand.

What happens if you show up without acceptable ID

If you arrive at the airport without any acceptable form of ID, TSA will not let you through the security checkpoint. You will not be able to board your flight. TSA can conduct additional identity verification on the spot—they may ask you questions about your personal history or request other documents—but this process is slow and often unsuccessful. The safest approach is to verify before you leave home that you have an acceptable ID and that it is not expired.

If you realize at the airport that your license is expired or you've left it at home, you have limited options. Some airports have DMV offices or passport acceptance facilities on-site, but these typically cannot issue a replacement on the same day. Your best option is to reschedule your flight if possible. If you must travel, contact the airline directly to ask whether they have any procedures for passengers without ID; policies vary, and some airlines may refuse to board you regardless of what TSA says.

Renewing your license before a trip

If your driver's license is expiring soon, renew it before your flight. Most states allow online renewal for standard license updates, though some require an in-person visit to a DMV office. Processing times vary—some states issue a temporary license when ready and mail the physical card later, while others require you to wait for the card to arrive before you can use it.

Check your state's DMV website for renewal procedures and timelines. If you're cutting it close, call your local DMV office to ask how long processing takes and whether you'll receive a temporary license you can use for travel. Arriving at the airport with a temporary license that shows your name, photo, and expiration date is generally acceptable to TSA, though having the permanent card is preferable.

Frequently Asked Questions

Can I use an expired driver's license if I'm only flying domestically?

No. TSA will not accept an expired license for any flight, domestic or international. The expiration date is checked at the security checkpoint. If your license expired, you'll need a different form of acceptable ID or a renewed license.

Do I need a passport if I'm flying to Puerto Rico or U.S. Virgin Islands?

No. Puerto Rico and the U.S. Virgin Islands are U.S. territories, so flights there are treated as domestic. A regular driver's license is sufficient. However, some airlines may ask for additional ID, so check with your carrier before traveling.

What if my state's driver's license doesn't have a Real ID star?

After May 7, 2025, you can still fly domestically, but you may experience additional screening at security. Bring a second form of ID (like a passport) to avoid delays, or visit your state's DMV to obtain a Real ID-compliant license.

Can I use a digital or mobile driver's license for flights?

Currently, TSA does not accept digital or mobile versions of driver's licenses at airport security checkpoints. You must present a physical card. Check the TSA website for updates, as policies may change.

What if I'm flying with a learner's permit instead of a full license?

A learner's permit is not an acceptable form of ID for air travel. You need a full driver's license, state ID card, passport, or another document on TSA's approved list.
