What is the youngest age for a belly button piercing in Kansas?

In most U.S. states the youngest age someone can get any body piercing is 16 but they must have their parents consent, meaning that the parent/guardian must go with the minor. Both the parent/guardian must have i.d. the parent can bring your birth certificate or your passport if you do not have any form of i.d like a drivers license. That's necissary to prove that they are really your guardian. If you are 18+ then you don't need a parent/guardian. If a shop doesn't ask for that then I would not trust them cause they obviously don't care if they lose they're licenses.
