Checking IDs at a California liquor store: the rules, and how ID scanners help

Ask for a government photo ID, look at it, and check that the photo, description and date of birth match the person in front of you. In California, a store that asks for and inspects a genuine-looking ID, and reasonably relies on it, has a legal defense if the buyer turns out to be under 21. Since January 1, 2026, a new law adds that if you also use an ID scanner and it misses a fake, that counts as evidence in your favor, as long as you inspected the ID too.

Here's what the law expects at the counter, how to spot fakes, how to train staff, and where a scanner fits.

What counts as a valid ID in California?

Under Business and Professions Code section 25660, acceptable ID is a document issued by a federal, state, county or municipal government (or one of its agencies) that contains the person's name, date of birth, description and picture. A driver's license or state ID card qualifies. So does a valid passport from the United States or another country. (California ABC, Business and Professions Code section 25660)

The defense: ask, inspect, rely

The law protects a store that:

1. Asks for that kind of ID,
2. Inspects it, and
3. Reasonably relies on it.

"Reasonably" is the part that matters. If the photo clearly isn't the customer, or the card is obviously altered, relying on it isn't reasonable, and the defense may not hold.

What changed in 2026: ID scanners (AB 509)

AB 509 (Chapter 264, Statutes of 2025) amended section 25660 and took effect January 1, 2026. In the words of California's Department of Alcoholic Beverage Control (ABC), it:

"establishes that the 'use of an active age verification software or an age verification device', as defined, that fails to identify a fake identification used in an alcoholic beverage transaction be considered evidence in a criminal prosecution or administrative hearing if the ID is bona fide evidence of majority and identity under Business and Professions Code section 25660 (a), is inspected, is seemingly legitimate, and matches the physical appearance of the customer, as specified."

ABC adds that the bill "simply makes it additional evidence if the licensee uses an age verification device or age verification software, provided that they inspected the ID." (California ABC, 2025 chaptered legislation, summary page)

What that means at the counter:

• A scanner adds to a clerk's check. It doesn't replace it.
• The clerk still has to look at the card and the customer.
• If the scan passes but the photo doesn't match, don't sell.

What happens if you sell to a minor?

ABC runs decoy operations, sending people under 21 into stores to try to buy. A sale can lead to action against your license and penalties for the clerk who made it. The penalty depends on the case and on past violations. ABC's site and your own attorney are the right sources for what applies to your license.

How to spot a fake ID

• Hold it. Take the card out of the wallet or sleeve. Look at both sides and feel the edges. Peeling layers, raised spots or a blurry photo are warning signs.
• Compare it with a real one. You see real California cards every day. If the colors, fonts or layout look off next to the ones you know, look closer. On REAL ID cards, California prints a golden bear and a star in the top right corner. (California DMV)
• Compare the person. Height, eye color and the photo. Ask a question the ID answers, like their zip code or birth year.
• Check the date. Make sure the card hasn't expired and the date of birth adds up to 21 or older today.

Training your staff

• ABC's LEAD program is free. LEAD (Licensee Education on Alcohol and Drugs) is a free, voluntary program for off-sale licensees and their employees, available online at lead.abc.ca.gov or in person. (California ABC, LEAD Training)
• Set a store rule and write it down, for example "ID everyone who looks under 40." A clear rule is easier to follow than a judgment call on a busy night.
• Practice the refusal. "Sorry, I can't sell this without a valid ID" is enough. No argument, no exceptions for regulars' friends.
• Back your staff when they refuse a sale.

How an ID scanner helps at the register

Most California licenses carry a barcode on the back that holds the date of birth. A scanner reads it and does the math, so nobody has to work out an age in their head.

In Ceyyo, the cashier scans the license with the same scanner they use for products. The register shows "ID checked · Age 34" when the customer is old enough, or opens the ID check screen when they're not. If the cashier checks a card by hand, the sale shows "ID verified". Ceyyo doesn't store the customer's name, address or license number.

The scan is the second check. The clerk looking at the card and the customer is still the first. Under AB 509, the scan only counts in your favor if that look happened.
