26 states make you check ID before a tattoo. The other 25 give you a reason to.

A client hands you a license. Whether you have to look at it, write down which one it was, or keep a copy in the file depends on the state you are standing in. Here is what all 50 states and the District of Columbia say about a photo ID before a tattoo, in one table, each row read from the state's own rule and linked to it.

26 states make you check ID in some form. 14 of those want a copy of it in the client's record, 4 want you to write down which ID you saw, 6 say check it and leave the rest to you, and 2 put a condition on it: New Jersey wants proof of age on the form itself, and North Dakota wants the parent's ID for a minor and lets Fargo ask everyone. 22 have no state ID rule at all, and 5 of those name a county or city that does. Massachusetts puts the date of birth on the record and lets Boston ask for the ID. Ohio writes the check as your defense rather than your duty, which comes to the same thing on a bad day. Vermont's rule says nothing either way.

The 22 with no rule are not 22 places where a fake ID is somebody else's problem. Every one of them bans tattooing anyone under 18 without a parent, and in most of them the only defense the statute gives a shop is that it looked at an ID and had reason to believe it. The details are under the table.

12 rows carry a * after the name. That marks a medium-confidence read: the citation is real and linked, but the rule behind it is thinner, older or more scattered than most, and the state's page says why. Each state name links to its page on this site, which carries the whole rule: the age, the record, the consent form, who inspects you.

This is a plain-language summary, not legal advice. Your local health department has the final word. Ask them, and bring your records.

Where there is no rule, check anyway

Washington's tattoo rule sets no ID requirement, and then RCW 26.28.085 makes a real attempt to check a driver's license or other picture ID the only defense a shop has when a client turns out to be 17. Arizona writes it the same way: asking for age identification and relying on it in good faith is an express defense to prosecution under § 13-3721. Ohio's § 3730.08 shields you from an under-18 charge only if the client showed a driver's license, a commercial driver's license or a state ID card showing 18 or over, you compared it to the person in front of you, and it was not altered. Utah's defense is having reviewed, photocopied and kept the ID, so the copy is the defense, not the glance. Florida makes inspecting an ID that shows 18 or older the safe harbor for a client who lied about their age. California writes no ID rule at all and then makes tattooing a minor a crime under Penal Code § 653. Wisconsin makes it a forfeiture.

In none of those states does the rule say "check ID." In all of them, the shop that did not is the one with no answer. So the honest reading of the table is 51 for 51. Check ID for every client, every time. Where your state wants a copy, take the photo. Where it wants the type written down, write it down. Everywhere else, look at it and put the date of birth on the record, because 31 of the 44 rules that list the record's fields ask for the date of birth or the age whether or not they ever mention the ID.

What goes on the record

Where the rule names the ID, it names what to keep. Texas and Virginia want the age, the date of birth and the type of ID written into the record. Maine has the client write down the ID they showed and its serial number, and the artist checks the entry. Kansas wants the type named. 14 states want the copy itself: Arkansas, Delaware, Georgia, Iowa, Kentucky, Mississippi, Nebraska, Nevada, New Hampshire, Oklahoma, Oregon, Rhode Island, South Carolina and Utah. A copy does not mean a photocopier. A photo of the license, kept with the signed form, is a copy, and it carries the date it was taken.

For a minor, the states that allow one at all almost always want the parent's ID too, and often the paperwork proving the relationship: Michigan, Kentucky and New Jersey say so in the rule, and El Paso County in Colorado asks for copies of both. Where your county is stricter than your state, the county is the rule you get inspected against.

The years you keep a record are half the rule. The ID is the half that decides whether the record was worth keeping. A file with a name and a signature says a person signed. A file with the ID says who.
