Quick answer
18. Puerto Rico’s legal drinking age is 18, not 21. Puerto Rico’s Internal Revenue Code bars anyone who sells alcohol from selling or giving it to a person under 18, and requires sellers to ask for photo ID from anyone who looks younger than 27.
- Carry a government photo ID (driver’s license or passport). You will be asked for it.
- Some bars and clubs run a 21+ door policy. That is a house rule, not the law.
- Casinos admit adults from 18: Puerto Rico law bars anyone under 18 from a gambling room.
- The 18 rule ends at the airport: once you are back in a US state, that state’s 21 minimum applies.
Quick answer
The legal drinking age in Puerto Rico is 18. Puerto Rico sets its own alcohol law, and its Internal Revenue Code bans selling or giving alcohol to anyone under 18.
- Bring photo ID. Sellers must check the ID of anyone who looks under 27.
- Some bars and clubs are 21+ or 23+. That's the venue's rule, not the law.
- Casinos: 18+.
- Driving: if you're under 21, the blood-alcohol limit is 0.02%, so don't drink and drive at all.
- Flying home: the 18 rule stops at the gate. On the mainland, the 21 minimum applies again.
Where the 18 rule comes from
Puerto Rico isn't a state, so the 1984 federal law that pushed every state to 21 (by tying it to highway money) doesn't set Puerto Rico's age. Puerto Rico's own code makes it unlawful for a seller to sell or give alcoholic drinks to a person under 18. Puerto Rico has kept 18 for decades.
What 18–20-year-old visitors should expect
- ID checks are routine. Use a driver's license or passport. Don't count on a phone photo.
- House rules vary. Some Old San Juan and Condado bars set a 21+ or 23+ door policy, especially late at night. Check before you build a night around one place.
- Hotel bars and casinos serve and admit adults from 18. Puerto Rico law bars under-18s from gaming rooms.
- Cruise ships set their own age (often 21 on US-based lines), even when docked in San Juan.
Drinking and driving
Puerto Rico's Vehicle and Traffic Law (Ley 22-2000) sets a 0.08% limit for adult drivers and 0.02% for drivers aged 18–20, so a single drink can put you over. Take a taxi, Uber (available in the San Juan metro area) or a designated driver.
Where you can drink
Bars, restaurants, colmados, supermarkets and liquor stores all sell alcohol. Many towns, including San Juan, restrict open containers on the street and set late-night sales hours for some areas. Rules change by town and by event, so follow posted signs and ask your bar.
