We pierce those 18+ with valid photo ID. We need the ID every time you need any procedure performed, even if you have shown it on a prior occasion.
For any piercing of a minor, a parent or legal guardian must be present to sign a consent form. Proof positive, state issued photo identification is required from the legal guardian, and a bona fide form of identification from the minor. In the event the parent has a different last name and/or address from the child, court documentation is needed to prove the relationship, i.e., divorce papers, or a remarriage certificate.
Piercing minors, including lobes for children 8+, is done on a case-by-case basis; the minor must show that they understand the responsibilities and commitment associated with the receiving and care of a piercing, they cannot be coerced or talked-into getting the piercing.
