Age-restricted products: ID checks and staff training

An ID check takes ten seconds, and it's one of the most important ten seconds at the counter. Age verification training teaches cashiers which products need an ID check, how to read an ID quickly, how to use the POS prompt, and how to refuse a sale politely. The federal minimum age for age-restricted nicotine products is 21, and state and local rules can be stricter. The store stays responsible for every sale, no matter what the register says.

Here's the straight version: a good ID habit protects your license, your staff, and your community.

Which products need an ID check?

It depends on what your store sells and where you are. Common categories include age-restricted nicotine products, some beverages, lottery in some states, and certain other items.

For age-restricted nicotine products, federal law sets the minimum age at 21. States and localities can set stricter rules, such as limits on certain product types or additional ID requirements.

Other products have their own rules, which vary by state and locality.

Make a list of every product your store sells that needs an ID check, with the minimum age next to each. Post it in the back room and cover it in training. Rules vary by state, so check your state and local requirements and update the list when rules change.

How should cashiers check an ID?

Teach a simple routine and use it every time.

Ask for the ID. Many stores ask everyone who looks under a certain age, well above the legal minimum, so cashiers don't have to guess.

Take the ID in hand. Don't just glance at it in a wallet.

Check the photo against the person.

Check the date of birth and do the math, or use the POS if it calculates age.

Check the expiration date. Many stores don't accept expired IDs.

Look for signs of tampering, like peeling layers, odd fonts, or mismatched details.

If anything seems off, don't make the sale.

Practice with sample dates until the math is quick. "Born on this date, is that 21 or older today?" should take a second or two.

How do POS prompts help, and what are their limits?

Many POS systems can flag age-restricted items when they're scanned. The register prompts the cashier to check an ID and sometimes to enter or scan the date of birth.

That prompt is a helpful reminder. It's not a replacement for the check. The cashier still has to look at the ID, compare the photo, and make the decision. And the store stays responsible for the sale.

Make sure your age-restricted items are set up correctly in the POS so the prompt appears. Review settings when you add new products.

If you're choosing or reviewing a POS, learn about NRS POS. For a general overview of how POS systems work, Investopedia explains the point of sale.

How do you refuse a sale politely?

This is where new cashiers need the most practice.

Stay calm and friendly. "I'm sorry, I can't sell this without a valid ID."

Don't argue or explain at length. A short, polite answer is enough.

Don't make exceptions for friends, regulars, or someone who says they "forgot it in the car."

If a customer gets upset, call a manager.

Back your staff. A cashier who refuses a sale correctly should hear "good job," never pressure to bend the rules.

Role-play in training. Have the new cashier practice refusing a sale with a coworker. It makes the real moment much easier.

How do you keep training current?

Train every new hire before they work the register alone.

Refresh training for all staff a few times a year.

Update your product list and training when rules change.

Keep a record of who was trained and when.

Post a clear sign at the register about ID checks. It sets expectations before the customer reaches the counter. For sign supplies, browse the office and school supplies category on NRS Marketplace. For industry resources on age-restricted sales, NACS publishes information for convenience retailers.
