Most people reach for their driver's license when they head to the airport — it's the most common form of photo ID Americans carry. But what happens if you don't have one, it's expired, or it isn't Real ID-compliant? The short answer is: you may still be able to fly, but the requirements and alternatives depend on several factors that vary by traveler and situation.
Flying domestically within the United States requires identity verification at TSA security checkpoints. For decades, a standard state-issued driver's license was enough. That began to change with the REAL ID Act, passed by Congress in 2005 following the 9/11 Commission's recommendations. The law established minimum federal standards for state-issued IDs and driver's licenses to be accepted for certain federal purposes — including boarding domestic flights.
The TSA enforces these requirements at airport security. What you need to get through depends on whether your ID is REAL ID-compliant, what other documents you carry, and in some cases, your age.
As of May 7, 2025, the TSA requires a REAL ID-compliant driver's license or another accepted form of identification to board domestic flights in the U.S. Before that date, non-compliant licenses were still accepted at many checkpoints during a long phase-in period. That grace period is now over.
A REAL ID-compliant driver's license typically displays a gold or black star in the upper corner — though the exact marking varies slightly by state. If your license doesn't have that marking, it may not be accepted as a standalone document at TSA checkpoints for domestic air travel.
States issue REAL ID-compliant licenses, but not all driver's licenses are automatically REAL ID-compliant. When you apply or renew, you generally choose whether to obtain a REAL ID version, which requires additional documentation (typically proof of identity, Social Security number, and two proofs of state residency). Some states automatically issue REAL ID licenses; others require you to opt in.
Not having a driver's license — or having a non-compliant one — doesn't automatically ground you. The TSA accepts a range of other identity documents for domestic travel, including:
| Accepted ID Type | Notes |
|---|---|
| U.S. passport or passport card | Accepted regardless of REAL ID status |
| Department of Defense ID | Military and dependents |
| Permanent resident card (Green Card) | Issued by DHS |
| DHS trusted traveler cards (Global Entry, TSA PreCheck, NEXUS, SENTRI) | Card must be valid |
| Tribal Nation-issued photo ID | Must meet TSA standards |
| HSPD-12 PIV card | Federal employee/contractor ID |
| Enhanced driver's license (EDL) | Issued by select states — not the same as REAL ID |
Children under 18 are generally not required to provide ID when traveling with a companion domestically, though airline policies may differ.
The full and current list of accepted documents is maintained by the TSA directly — and that list can be updated.
The TSA has a process for travelers who arrive without compliant identification. You may be asked to complete an identity verification process, which can include providing personal information and answering questions to confirm your identity. If identity can be verified through that process, you may still be allowed to proceed — though typically subject to additional screening.
This is not guaranteed, and the process can add significant time at the checkpoint. It also isn't available for international travel, where passport requirements apply regardless of your driver's license status.
Whether your driver's license works at the airport comes down to a few specific variables:
Whether you can fly without a driver's license, or whether your current license is sufficient, ultimately depends on what state issued your license, when you last renewed it, whether you opted into REAL ID at that time, and what other identification you have available. Someone with a valid U.S. passport faces no complications at all. Someone with only a non-compliant state license issued before their state fully implemented REAL ID faces a different situation entirely.
The TSA's current accepted ID list, your state DMV's REAL ID status information, and your own license's compliance marking are the three things that determine where you actually stand.
