Age of seller and server laws set a minimum age for sellers in off-premise locations that sell alcohol and servers and bartenders in on-premise locations. Some states specify a separate minimum age to handle beer, wine, and spirits, and require a manager or supervisor to be present when an underage employee sells, serves, or dispenses alcoholic beverages1.
Expected Beneficial Outcomes (Rated)
Reduced underage drinking
Other Potential Beneficial Outcomes
Reduced alcohol-related crashes
Evidence of Effectiveness
There is insufficient evidence to determine whether age of seller and server policies reduce underage drinking. Available evidence suggests that underage sellers are more likely to sell alcohol to customers under the age of 212, 3 and to intoxicated patrons4. States with legislation that requires a minimum age of 21 for bartenders appear to have fewer alcohol-related fatal crashes among underage drivers than states with a younger minimum age or no required age5, 6; however, regulations that establish a minimum age for sellers and servers do not appear to affect alcohol-related fatal crashes5, 6, 7. Additional evidence is needed to confirm effects.
Impact on Disparities
The minimum age required for sellers in off-premise locations and servers and bartenders in on-premise locations varies by state. As of January 2016, the minimum age to serve alcohoic beverages ranges from 17 in Maine to 21 in Alaska, Nevada, and Utah; most states set a minimum age of 18. Ten states require a manager to be present when underage servers are working8.
