Currently, your Oklahoma driver's license is an acceptable form of ID.
The WRWA staff has recently been receiving a lot of questions regarding the REAL ID Act. Oklahoma travelers want to know if they can use their Oklahoma driver’s license as identification when they fly. Your Oklahoma driver’s license is an acceptable form of ID until January 22, 2018.
Beginning January 22, 2018, passengers who have driver’s licenses or identification cards issued by a state that is not compliant with REAL ID, and that state has not received an extension, will need to show another acceptable form of identification for domestic air travel.
Currently the state of Oklahoma is not compliant and is operating under an extension for compliance. If the state does not receive another extension, air travelers will be required to use a Federal ID such as a passport for domestic travel beginning January 22, 2018. If the state does receive an extension, current Oklahoma driver’s licenses will be accepted until October 1, 2020.
The REAL ID factsheet provides additional information as does TSA’s FAQ’s and the DHS Brief.
