Underage sales usually happen on a busy shift, when a clerk who knows the rules skips a step to keep the line moving. Compliance checks are routine. Regulators and local police send underage buyers into stores to see whether clerks ask for ID, and the clerk on the register has no way of knowing which customer is the test.

Your protection is a habit that holds up under pressure: the same check on every sale, on every shift. Here’s how to build it.

This is general information, not legal advice. Federal, state and local rules all apply, and where they differ, follow the strictest one.

The rules

Tobacco

• The federal minimum age to buy any tobacco product is 21. That covers cigarettes, cigars, smokeless tobacco, nicotine pouches, e-cigarettes and vapes. It has been federal law since late 2019.
• Federal rules require a check of photo ID with a date of birth for any tobacco buyer under 30. Since nobody can reliably tell 29 from 31 by looking, a card-everyone policy removes the guesswork.
• States, counties and cities can add their own rules on top, such as licensing, product restrictions and display rules.

Check FDA’s website, fda.gov, for current federal tobacco rules and free retailer materials, and your state and local licensing authority for the rest.

Alcohol

• The minimum age to buy alcohol is 21 in every state.
• Nearly everything else is set by your state, and sometimes by your county or city: sale hours and days, which IDs are acceptable, how old a clerk must be to sell alcohol and whether seller training is required.
• Your license may carry its own conditions. Know what yours says.

Your state’s alcohol control agency is the place to check.

A good ID check, step by step

1. Ask. Ask every customer your policy covers. A card-everyone policy is the easiest to train and the hardest to argue with.
2. Hold it. Have the customer take the ID out of the wallet and hand it over. You can’t feel the card or see the back through a plastic sleeve.
3. Check the date. Compare the date of birth with today’s “born on or before” date. For example, if today is October 21, 2026, a customer must have been born on or before October 21, 2005 to buy. Keep that date where the cashier can see it, and update it every morning.
4. Check that it’s valid. Make sure it isn’t expired, if your state requires an unexpired ID, and that it’s a type your state accepts, such as a driver’s license, state ID card, passport or military ID.
5. Check that it’s theirs. Compare the photo with the face in front of you, and the height and eye color with the person. Asking for the ZIP code or middle name on the card is a quick test.
6. Check for tampering. Feel for raised edges or bumps, look for mismatched fonts or a damaged photo area, and look for the card’s security features.
7. Refuse politely when something is off. “Sorry, I can’t sell this without a valid ID” is enough. Don’t argue, and don’t keep the customer’s ID unless your state’s law says you may.

Many states print licenses for drivers under 21 in a vertical layout. A vertical license is a cue to slow down and do the math carefully.

Set up the register to help

A register can’t replace a careful look at an ID, but it can make sure the question gets asked.

• Age restrictions on every restricted department and item. Tobacco, vapes, nicotine pouches, alcohol and anything else your state restricts should prompt for an age check when scanned.
• New items. Check the age setting every time you add an item. A new vape or pouch added to the wrong department rings up with no prompt at all, and it’s an easy gap to miss.
• ID scanning. Many registers can read the barcode on the back of a driver’s license and work out the age. That’s faster and avoids math mistakes. It only reads what’s on the card, though. It doesn’t prove the card belongs to the customer, so the clerk still compares the photo.
• Bypass keys. Some registers let a clerk skip the scan, for example with a visual check button. Decide whether you want that option at all and, if so, who may use it. If your register records bypasses, review them.
• Sale hours. If your register can block alcohol sales outside legal hours, set it to match your state and local rules.

Training

Train every new clerk before their first shift on the register, and refresh everyone regularly. Cover:

• The federal, state and local rules for your store
• Your store’s written ID policy
• The ID check steps above, with hands-on practice
• How to spot a fake or borrowed ID
• How to refuse calmly, and when to call a manager
• Sales to an adult who seems to be buying for someone underage, which you can refuse

Use free materials where they exist. FDA publishes tobacco retailer training materials, and many state alcohol agencies offer or approve seller training. In some states, approved training can be taken into account if a clerk makes a mistake.

Keep a signed record for each employee: the date, what was covered and who did the training. Have each employee sign your ID policy, too.

Practice between trainings. Role-play at shift change, and quiz staff on today’s born-on-or-before date. Some owners hire adult mystery shoppers who look young to see whether clerks ask for ID.

Keep a refusal log

Write down every refused sale at the counter, on paper or in whatever system you use:

• Date and time
• Product
• Reason: no ID, expired ID, under age, suspected fake or buying for someone else
• Clerk’s name
• A short description of the person, if useful

A refusal log shows that your staff check IDs and turn sales down. It helps you coach clerks and spot people who try again and again. It also backs up your side of the story if a sale is ever questioned. Review it every week and thank the clerks who refuse. Turning down an angry customer takes nerve, and it’s exactly what you want them to do.

Don’t record more personal information than you need. A description is usually enough. Don’t copy or photograph IDs unless your state’s rules allow it.

A quick checklist

• Federal, state and local rules known, and your policy written down
• Age restrictions set on every restricted department and item
• New items checked for age settings when they’re added
• Born-on-or-before date visible at the register and updated daily
• Every clerk trained and signed off
• Refusal log at the counter and reviewed weekly
