Which of the following is an acceptable form of identification to check a guest's legal drinking age?

A passport is an acceptable form of identification to check a guest's legal drinking age because it is an official government-issued document that verifies a person's identity and date of birth. Passports include essential details such as the bearer’s full name, date of birth, and photograph, making them reliable for confirming age. Since they are issued by a national authority, they meet the legal standards for identity verification in many jurisdictions.

Other forms of identification, while they may include a person's birth date, may not be universally accepted in all establishments. For example, a birth certificate serves as proof of age but is less practical for identification purposes in public venues. A student ID might not necessarily include a date of birth and typically does not carry the same authority as government-issued documents. Credit cards, while commonly used for transactions, do not inherently indicate the person's age and are often not accepted as age verification due to their potential for fraud. Therefore, the passport stands out as the most reliable option for confirming a guest's legal drinking age.
