Checking Identification and Preventing Sales to Minors

Domain 2 - Checking Identification and Preventing Sales to Minors

This domain tests how a server verifies age and prevents underage sales. The exam focuses on acceptable ID, the steps of a proper check, how to calculate age on the birthday, and what to do when an ID is expired, altered, borrowed, or simply doubtful. Hawaii's minimum drinking age is 21, and a server who accepts weak or invalid proof of age risks administrative, criminal, and civil consequences.

Acceptable ID and the check

Commonly accepted proof-of-age documents in Hawaii include a valid Hawaii driver's license or Hawaii state identification card, a valid U.S. passport, a valid U.S. military identification card, and a valid foreign passport. County rules can differ on foreign driver's licenses, so a passport is the safer foreign document. An expired ID is not valid proof. A vertical driver's license usually signals a person under 21.

Check in this order:

  1. Ask for ID whenever the customer appears young or there is any doubt.
  2. Inspect the photo and compare it with the customer's face.
  3. Read the date of birth and calculate the age carefully.
  4. Check expiration, holograms, font, and signs of alteration.
  5. Return the ID and either proceed or refuse service.

If the ID is fake, borrowed, altered, or expired, do not accept it. Refuse the sale, notify the manager, and document the incident. Do not confiscate an ID unless your employer's policy and local law clearly permit it; refusal is the priority.

Worked example

A customer presents a Hawaii driver's license showing a date of birth of July 4, 2004. Today is July 3, 2025. The customer is still 20 because the birthday has not arrived; the server must refuse alcohol service. On July 4, 2025, the customer turns 21 and may be served, subject to all other rules. If the license expired in June 2025, it is not valid proof even after the birthday.

Traps that cost marks

  • Counting the birth year only and ignoring whether the birthday has occurred.
  • Accepting an expired ID because the birth date looks correct.
  • Accepting a photo of an ID on a phone.
  • Assuming a foreign driver's license is always acceptable; check county rules or ask for a passport.
  • Serving a minor because an older friend vouches for them.
