The nine states are Kentucky, Maine, Minnesota, Missouri, Montana, Oklahoma, Pennsylvania, South Carolina, and Washington. Each of these states does not currently issue a state ID that lives up to federal ID minimum security requirements, according to the REAL ID Act of 2005. That means these states have about three months to make changes to their state IDs or drivers licenses so that they meet federal government standards. Otherwise, you'll need to apply for or renew a passport—or at the very least, find yours, wherever you stashed it after the last trip—before passing TSA and getting on a commercial airplane to another U.S. city. Other forms of ID that will work are permanent resident cards (green cards) or military IDs.This story was posted in October and the deadline was in January, which has already passed. Does anyone know how it was resolved?
