Tattoo Laws & Piercing Laws in the U.S.

What are the laws and regulations in the U.S. governing body art practices?

There are no federal laws concerning any of the procedures and practices associated with body art. Some states have absolutely no laws regarding body art and safe procedures, while others only regulate according to age, making it against the law to tattoo, pierce or brand anyone under the age of 18 without parental consent. Tattooing has been outlawed in Connecticut, Florida, Kansas, Oklahoma, South Carolina, Vermont and Albuquerque, New Mexico. It is important that you contact your local health department to find more information regarding the regulations in your state. For Pennsylvania, you may visit www.health.state.pa.us.
