What is one of the identifiers on a personal identification certificate issued to individuals under 21?

The presence of "UNDER 21" printed on the face of a personal identification certificate serves as a clear indicator of the individual's age status. This label helps to differentiate those who are under the legal drinking age, which is crucial for enforcing laws relating to alcohol consumption and purchase. By having this explicit marking, it becomes easier for businesses and law enforcement to quickly verify a person's age, ensuring that regulations are adhered to.

The inclusion of this information is vital for preventing the unlawful sale of alcohol and promotes responsible practices in settings that serve or sell alcoholic beverages. It also aids in avoiding potential legal consequences for establishments that might inadvertently serve underage individuals.

Understanding this key identifier is important for both compliance with regulations and the public’s safety, making it an essential feature of identification for those under 21 years of age.
