Yes. Bars, liquor stores, tobacco shops and dispensaries in Michigan can scan IDs to verify age. Alcohol sellers must make a diligent inquiry into every buyer’s age, and examining an accepted picture ID meets that duty.
Michigan makes skipping the age check a crime on its own. Under MCL 436.1701, failing to make a diligent inquiry into a buyer's age is a misdemeanor, and being shown an accepted ID is a defense a scan helps you prove. A first sale to a minor can bring a $1,000 fine, 60 days in jail, and Liquor Control Commission action.

Can you scan IDs in Michigan?
Yes. Michigan alcohol sellers must make a diligent inquiry into a buyer’s age, and examining an accepted picture ID meets that duty. Dispensaries must check every customer, and tobacco shops must card buyers who appear under 27. A scan checks the ID fast and leaves a record. The minimum age is 21 at bars, stores, tobacco shops and dispensaries, and federal rules add a check for tobacco buyers under 30.
What counts as a diligent inquiry
A diligent inquiry is a good-faith effort to learn the buyer’s age. It must include at least one of these:
- Examining a Michigan driver’s or chauffeur’s license or state ID card
- Examining a military ID or another bona fide picture ID showing identity and age
- Using a secure identity verification device that matches a biometric scan to a verified picture ID
If you demanded and were shown an accepted ID before the sale, that’s a defense. For the exact wording, see MCL 436.1701.
Which IDs are accepted in Michigan?
You can accept a Michigan driver’s or chauffeur’s license, a Michigan personal ID card, a military ID, or another bona fide picture ID showing identity and age, but never a fraudulent ID.
Michigan doesn’t issue a mobile driver’s license yet. Bills to allow one were still in a Senate committee in March 2026.
Fines for selling to minors in Michigan

| Selling alcohol to a minor, or no diligent inquiry | Up to $1,000 and/or 60 days. Repeat: $2,500 and/or 90 days |
