Guam sets its legal drinking age at 21, the same as every US state. This applies uniformly to buying alcohol at a store, ordering at a bar or restaurant, and simply possessing alcohol in public.
This can catch visitors from countries with a lower drinking age off guard — Japan and Korea, for example, both set the age at 19–20. If you're 19 or 20 and visiting from a country where that's legal, alcohol is still off-limits to you in Guam.
Bars, restaurants, and stores in Guam commonly check ID for anyone who appears under roughly 30–35 years old — this is standard US practice, not a sign of suspicion. A passport is always accepted; a foreign driver's licence with a clear date of birth is usually accepted too.
Carry physical ID, not just a photo of it on your phone — most venues in Guam require the original document.
Drinking alcohol on the beach is commonly tolerated in the Tumon tourist area, particularly at hotel-adjacent stretches, but it's not guaranteed everywhere — look for posted signage, and never assume open containers are fine outside clearly tourist-facing beach areas.
Hotels, resort bars, and restaurants serve alcohol under standard licensing. Some public parks and government-managed sites prohibit alcohol outright — respect posted rules, particularly at cultural and historical sites like War in the Pacific National Historical Park.
Driving under the influence is enforced under US-standard DUI law. Do not drive after drinking — arrange a taxi or hotel shuttle instead.
