Pennsylvania law does not give a minimum age for persons getting tattooed, as long as the minor has the consent of a parent or legal guardian. The consenting parent must also be present at the time of the tattooing.
Even though Pennsylvania doesn't set a minimum age for tattoos with parental consent and presence, county and local ordinances should indicate specific restrictions. In addition, many shops have their own limits and restrictions.
For example, Ink Assassins of Erie, P.A., will do tattoos for minors between 16 and 18, if they present identification and are accompanied by a parent with proper identification. On the other hand, Atom Age Tattoos of Mechanicsburg, P.A., will do tattoos for minors aged 15 to 17 with parental consent and presence. Because of these differences, it's always best to check the policies of the shop and artist before making an appointment.
