Checking ID & Preventing Sales to Minors
In Texas a minor is anyone under 21, and preventing sales to minors is one of a seller-server's most closely watched duties. This chapter explains how to check identification properly, which IDs are acceptable, how to spot fake or altered cards, how to calculate age from a date of birth, and the rules and narrow exceptions for minors. It also covers how TABC minor-sting operations work and why consistent carding is the only reliable protection.
The legal age and who must show ID
For alcohol purposes, a minor in Texas is any person under the age of 21. It is illegal to sell, serve, or make alcohol available to someone under 21 except in narrow statutory exceptions. Because appearances can be deceiving, a common best practice is to check identification for anyone who appears to be under a generous age threshold, such as 30 or even 40. Every individual person who will consume alcohol must show their own valid proof of age; friends vouching, or one person's ID covering a group, is never acceptable. If some members of a group have ID and others say theirs is 'in the car,' only those who present valid identification may be served.
Acceptable identification and inspecting the card
Acceptable identification is a valid, unexpired, government-issued document that includes a photo, such as a driver license, state ID card, passport, or military ID. A photocopy, a school library card, or a handwritten note is not acceptable proof of age. Good ID practice means physically handling and inspecting the card rather than glancing at it, confirming it is genuine and unaltered, and comparing the photo and the printed physical description, such as height and weight, to the actual person presenting it. If a server cannot confirm that an ID is valid and that the person is 21, the correct choice is to refuse the sale, following house policy and involving management when documents are unclear.
Spotting fake or altered IDs and calculating age
Warning signs of a fake or altered ID include a photo that does not match the person, physical tampering such as peeling edges or raised, re-glued numbers, and a printed height, weight, or description that clearly does not match the customer. Another common tactic is a young person using a real ID that belongs to an older sibling or friend, which is why comparing the photo and asking verifying questions matters. Calculating age correctly is essential: a person only reaches an age on the birthday itself, not at the start of the birth year. For example, on January 15, 2026, someone born March 10, 2005 is still 20 because their 21st birthday has not yet occurred, and they must be refused.
Minor rules and narrow exceptions
Texas law makes it illegal for a minor to purchase alcohol, to generally possess alcohol in public, and to consume alcohol, each of which can be a separate offense. A narrow exception allows a minor to be furnished alcohol by, and in the visible presence of, their adult parent, legal guardian, or spouse; promises not to drive, a birthday that is close, or a friend over 21 vouching are not exceptions. Servers must also watch situations where a legal-age adult buys alcohol and then hands it to a visibly underage companion, which is illegal furnishing that the server should stop, even to the point of ending service to that table. A customer who is honestly under 21 still cannot be served, regardless of any sting or good tip.
Minor sting operations
TABC and law enforcement periodically run minor-sting or decoy operations to test whether staff properly check ID and refuse. In these operations an underage person attempts to buy alcohol, often presenting their real ID or none at all, and staff are not warned in advance which customer is the decoy. The individual employee who makes an illegal sale during a sting can be cited, and the business faces administrative action against its permit. A decoy who honestly states they are underage still cannot be served, and honesty about being a minor creates no exception. The only reliable protection is to card consistently and calculate age carefully on every single transaction.
