First question is are you 18? If your 18 and about to graduate high school and are male (which I assume you are seeing as your name is Nate) you have to be registered with the Selective Service before you can use ANY governmental or state benefit or process. Also, you mentioned getting charged but beating it. That WILL put you into the draft pool too. All males in the united states are required to be registered with the SS, when they check your SSN it shows if you are or aren’t. As a way of being D-bags they probably signed you up instead of punishing you. You do need to call and ask HOW you got registered, because the way you are registered can affect a lot of things in your future.
Also, if your planning on going to college you have to be (males) registered with SS to apply for grants, and you could get heavily fined or jailed for not being registered and pulling government money.
I highly suggest you go through google and read EVERYTHING there is to know about Selective Service, I didn’t have that opportunity when I was graduating high school.

If your 18 your parents can’t sign you up “legally” but it does happen a lot since they have your information. That’s still perjury, but if you wanted to sign up anyway you can let it slide. But seriously call and find out how you got registered, they have to mail a card to your address and if someone signed up using your information the card won’t come to your address.
