It takes up to 15 business days—or three weeks—for you to receive your plastic driving license by mail in most states.
Drivers under 16 will likely have restricted driving privileges, even after graduating from a learner’s permit to a license. Most states remove restrictions at the age of 18 and grant a full license at 21.
In the meantime: Keep your permit and your paper license with you while you’re on the road, and follow any restrictions in place on your driving privileges. Your paper license will prove that you can legally operate a vehicle, but it does not provide identification like a plastic driver’s license with a photograph does.
