If you’re not quite ready, old enough, or in the market for a driver’s license but would still like to be able to prove to people that you exist, you can apply for a state-issued ID card. To get one of these bad boys, you need to present your social security number and an official document showing your birth date to the DMV. IDs expire at the end of your birth month each year divisible by five (15, 25, 80, etc.), so as long as you remember how old you are, it shouldn’t be too difficult to remember when to renew the card.
