What is the minimum legal age to purchase alcohol in Arizona?

The minimum legal age to purchase alcohol in Arizona is 21 years old. This age requirement aligns with federal regulations established by the National Minimum Drinking Age Act of 1984, which set the minimum drinking age at 21 across all states. The law aims to reduce alcohol-related accidents and promote public health, particularly among young people. Consequently, anyone under the age of 21 is prohibited from legally purchasing alcohol in Arizona, ensuring that access to alcoholic beverages is restricted to individuals who are of legal age.
