KNOXVILLE, Tenn. — If you haven't upgraded your driver's license to a Real ID yet, you still have plenty of time. 

Tuesday marks one year until the new IDs will be enforced in airports and government buildings. The state started issuing the new forms of identification on July 1, 2019.

But it's not mandatory to get a Real ID in the state of Tennessee unless you're flying out of state or the country. 

Tennessee has roughly 4.7 million valid license holders, according to the Tennessee Department of Safety & Homeland Security Driver Services Division. 

Since July 1, when the law went into effect, roughly 162,809 Real IDs have been issued, according to the Driver Services Division. That leaves 4,537,191 Tennesseans who don’t have Real ID yet.

If you do plan on getting a Real ID, you will need to bring one document proving your citizenship, one proving your social security number and name, and two forms of proof that you reside in Tennessee. You can find a list of the documents you can bring here. Also, if you have changed your name, you will need to bring that documentation, too.

You will have to take a new picture when you get your Real ID, and it will cost you $8 if it's your first time replacing a non-expired license or $12 if it's your second time doing so.
