The Transportation Security Administration (TSA) has begun alerting all airline travelers that starting Oct. 1, 2020, they will need a REAL ID-compliant form of identification to board a commercial flight. 

The Missouri Department of Revenue and the Office of the Illinois Secretary of State will join the TSA and St. Louis Lambert International Airport to remind the public that enforcement of the Real ID Act is one year away. Millions of airline travelers in every state will be impacted by the Real ID Act (2005) and could be turned away from checkpoints if their licenses or identification cards do not meet the new federal standards and they do not have another REAL ID-compliant form of identification such as a valid U.S. passport, passport card, military ID, etc..

The state agencies will detail latest requirements and procedures for Missouri and Illinois residents to obtain Real ID-compliant identification.
