The official age rating for Grand Theft Auto VI is M for Mature, set by the ESRB. That means you need to be at least 17 years old to purchase the game legally in the United States. Rockstar has not announced any separate in-game age gate or parental controls beyond what the consoles themselves offer.
Outside the US, ratings vary. PEGI gives the game an 18 rating in Europe, while Australia uses R18+. In both cases, the minimum age is 18. Some retailers may enforce these limits at checkout, but there is no official word on any additional age verification inside the game itself.
If you are under 17, you will need a parent or guardian to buy it for you on PS5 or Xbox Series X|S. The game launches digitally on November 19, 2026, with no physical disc, so the age check happens at the store account level, not at a counter.
