Since May 7, 2025, the U.S. Transportation Security Administration (TSA) has required all passengers aged 18 and older to present a REAL ID-compliant form of identification in order to board domestic flights. The REAL ID is only available to U.S. citizens and lawful permanent residents, which means that most Mexicans living, working, or visiting the United States—whether on a temporary visa, humanitarian permit, or without legal immigration status—cannot obtain it.
As a result, travelers without other TSA-approved identification may face restrictions when flying domestically. What many do not realize is that the SENTRI card (Secure Electronic Network for Travelers Rapid Inspection), issued by the Department of Homeland Security (DHS), is accepted by the TSA as valid identification for U.S. flights.
This card, part of the U.S. government’s Trusted Traveler programs, is commonly used by those who frequently cross the land border between Mexico and the United States. However, its validity extends beyond border crossings—it can also be used at airports.
The TSA also maintains a list of acceptable forms of identification, which it recommends checking regularly for updates.
TSA-Approved IDs for Domestic Travel in the United States
The following forms of identification are approved by the TSA:
- REAL ID-compliant driver’s licenses or other photo IDs issued by a state’s Department of Motor Vehicles (or equivalent). If you are unsure whether your ID meets REAL ID requirements, check with your state DMV. Temporary driver’s licenses are not accepted.
- Enhanced Driver’s License (EDL) or Enhanced Identification Card (EID) issued by a state.
- U.S. passport.
- U.S. passport card.
- DHS Trusted Traveler cards (Global Entry, NEXUS, SENTRI, FAST).
- U.S. Department of Defense identification, including dependent IDs.
- Permanent resident card.
- Border crossing card.

The implementation of the REAL ID has caused uncertainty among travelers, particularly for those who cannot obtain this type of identification, such as Mexicans without permanent residency in the United States. However, there are legal alternatives to continue flying domestically, and the SENTRI card remains one of the most practical options.
