A NYS driver's license is good for 8 years. There is an issue date and an expiration date shown on the front. If you are under 21, when you turn 21 you will get a new license without the under 21 code on it (for ID purposes). Also, you can renew your license up to a year before it expires, or up to 2 years (I think) AFTER it expires. After that, you have to take the test again. A NYS driver's license is good for 8 years.
