TSA REAL ID Enforcement: What Travelers Need to Know About Airport Screening Rules

Travelers age 18 and older passing through domestic Transportation Security Administration (TSA) airport checkpoints must present a REAL ID-compliant state credential or another federally accepted form of identification, a requirement that took effect on May 7, 2025. While some recent summaries characterize the policy as a new mandate starting this May following a Department of Homeland Security (DHS) final rule, established coverage from Airport Online and Ground News confirms that federal enforcement at commercial aviation checkpoints actually began on May 7, 2025.

The implementation marks the culmination of a federal identification standard first enacted by Congress in 2005. Under the current screening rules, adult passengers flying domestically can no longer rely solely on a standard, non-compliant state driver’s license to clear airport security, according to The Travel.

From Enactment to the May 2025 Enforcement Date

The statutory framework for the current airport screening rules dates back to 2005, when the REAL ID Act was enacted to establish stricter security standards for state-issued driver’s licenses and identification cards. However, full implementation faced repeated delays over the subsequent two decades, particularly during the COVID-19 pandemic when state licensing agencies experienced severe administrative bottlenecks.

In December 2022, DHS extended the federal enforcement deadline by 24 months, moving the implementation target from May 2023 to May 2025 due to pandemic-related state processing backlogs, according to The Economic Times. Although some policy summaries describe the May 2025 transition as the result of a new DHS final rulemaking ending pandemic extensions, reporting from Airport Online and The Economic Times simply treats May 7, 2025, as the established start of checkpoint enforcement rather than a newly issued regulatory action.

How to Identify a Compliant Credential

For everyday citizens and business travelers, the primary impact of the rule is the need to verify the status of their state-issued identification before heading to the airport. A REAL ID-compliant state driver’s license or identification card is commonly identified by a star marking located on the upper portion of the card, according to Airport Online and El Cronista.

Travelers holding a standard state-issued driver’s license that lacks the compliant marking face significant limitations at the airport. While a non-compliant standard license may remain legally valid for operating a motor vehicle and other state-level purposes, it is not, by itself, sufficient to clear a domestic TSA security checkpoint, according to Airport Online. Passengers age 18 and older who arrive at a checkpoint with only a non-compliant standard license will not meet the federal identification threshold required to board commercial flights.

Acceptable Alternatives at TSA Checkpoints

A common misconception surrounding the federal mandate is that domestic air travelers must possess either a REAL ID-compliant state license or a U.S. passport book. While some brief summaries emphasize only those two credentials, reports from The Travel and The Economic Times note that a U.S. passport is only one of several acceptable alternatives.

Travelers age 18 and older who do not have a REAL ID-compliant state card can still pass through domestic TSA security checkpoints by presenting other approved federal or state documents. According to Airport Online, The Travel, and The Economic Times, TSA-accepted alternatives include:

U.S. passports and U.S. passport cards
State-issued Enhanced Driver’s Licenses
DHS trusted-traveler cards
U.S. military identification
Other TSA-accepted identification documents
