The Transportation Safety Administration (TSA) has reached out to clarify that only IDs issued by compliant states can be used until 2020. IDs issued by states with extensions are valid until October 11, 2018.

According to sources, frequent flyers and credit cardholders have a list of deadlines to keep in mind if they’re hoping to take full advantage of their benefits — and earn or retain elite status. But several US states have had a looming travel-related deadline of their own to deal with, too, and it’s created a fair amount of buzz within non-compliant states.

The issue at hand is that a handful of United States states currently issue driver’s licenses dont meet the guidelines. Therefore, the Transporation Safety Administration previously announced that without an approved extension, it would no longer accept those documents for identity verification as of January 22, 2018. This has been indicated by signage at checkpoints throughout the United States.
