Department of Homeland Security pushes REAL ID deadline to 2023

The federal government is delaying the deadline for the REAL ID enforcement for a second time.

Every domestic air traveler 18 and older will need a REAL ID-compliant driver's license or identification card, state-issued enhanced driver's license or another TSA-acceptable form of identification beginning on May 3, 2023, the Department of Homeland Security announced Tuesday.

The original deadline of Oct. 1, 2020, was postponed for one year due to the pandemic. The second delay is also "due to circumstances resulting from the ongoing COVID-19 pandemic," according to the DHS press release.

"The pandemic has significantly impacted states’ ability to issue REAL ID-compliant driver’s licenses and identification cards, with many driver’s licensing agencies still operating at limited capacity," the release states.

Extending the deadline is the "right move," Tori Emerson Barnes, U.S. Travel Association executive vice president for public affairs and policy, said in a statement.

"Getting to REAL ID compliance on time was already going to be a challenge before COVID shut down DMVs for extended periods," Barnes said. "Significant travel disruption was likely if the deadline were allowed to hit, which the U.S. economy can’t afford after a $500 billion decline in travel spending last year and millions of travel jobs lost to the pandemic."

All 50 states, Washington, D.C., and four of the five U.S. territories covered by the REAL ID Act and related regulations are now compliant with REAL ID security standards, the government said.

The regulation was put in place in 2005 as a way to ensure travelers' identities following the 9/11 attacks, according to the DHS. Only recently did all 50 states come into compliance.

Currently, only 43% of driver's licenses issued in the U.S. are REAL ID-compliant, according to DHS data.
