The age at which a person can get a tattoo varies by state, from a total ban on tattoos for people under the age of 18 to laws allowing tattoos with parental consent and/or presence. As of 2014, South Carolina's laws are stricter, requiring parental consent until age 21.
No upper age limit exists in any state. The states that allow tattooing of minors with parental consent as of 2014 are Alabama, Arizona, Arkansas, Colorado, Connecticut, Delaware, Florida, Hawaii, Indiana, Kansas, Kentucky, Louisiana, Maryland, Michigan, Minnesota, Missouri, Montana, Nebraska, Nevada, New Jersey, New Mexico, New York, North Dakota, Ohio, South Dakota, Tennessee, Texas, Utah, Vermont, Virginia, West Virginia and Wyoming.
Sometimes consent must be given in person, and some states establish a lower age limit. Idaho requires written parental consent for minors between 14 and 18. The rest of the states fully ban tattooing of minors, with Georgia and Illinois making exceptions for tattooing under the supervision of a medical professional.
