I'll assume you're asking as a minor. In which case you need to get printed copies of your ID and your Guardian's ID, + a notarized paper signed saying you both understand the risks and such. Worth it though, to go to a professional and not get crooked/infected piercings!
18 and up under 18 with notarized consent form
How old do you have to be for what? You have to be 18 for any piercings or tattoos alone and if you're younger, you need an adult's consent.
