Starting Jan. 22, 2018, Pennsylvania residents will need more than just a driver's license to travel domestically.

Driver's licenses from the Keystone State are currently not compliant with the federal government’s Real ID Act which set tougher standards for IDs to improve security in 2005.

The state's Act 38 prohibits Pennsylvania's participation with Real ID, Pennsylvania Department of Transportation's Driver and Vehicle Services Spokesperson Alexis Campbell told Fox News.

But Pennsylvania residents won't be alone. Other states not currently in compliance include Kentucky, Maine, Minnesota, Missouri, Montana, Oklahoma, South Carolina and Washington.

A new bill introduced in congress could repeal Act 38 and open discussion as to whether the state wants its IDs to meet federal standards. "Repeal of the REAL ID Nonparticipation Act," or Senate bill 133 , was voted out of the Senate Communications and Technology Committee on Feb. 8, putting it one step closer to a senate vote. If implemented, the Real ID standards would require residents to show more forms of identification to obtain an ID.

The Department of Homeland Security explains further explains on its website that, "Preventing terrorists from obtaining state-issued identification documents is critical to securing America against terrorism.”

Pennsylvania is set to keep its current IDs for now, meaning residents will need a passport or another form of federally acceptable identification to fly within the U.S. next year.

TSA has started to notify airline passengers of the upcoming changes at airports across the country.

Residents going into federal buildings will need a new ID sooner-- Pennsylvania state IDs won’t be valid starting June this year.
