The minimum age for betting online is 21 in most US states and 18 in a few, and the rule can differ between sports betting, online casinos and lottery products. Your state sets the age, not the operator.

How the minimum age for betting works

The age is part of each state’s gaming law, and a state may use one age for sports betting and another for casinos or lottery, so check the exact product you want. Operators verify your date of birth with identity checks at sign-up, using records and ID documents, and they enforce the rule afterward by closing accounts opened with false details. Underage betting has real consequences: the operator can void bets and close the account, and the person may lose winnings and face penalties under state law.

Look up your state regulator’s page on the legal age, never register with someone else’s details, and never let a minor use your account. If you are under the legal age, wait until you reach it.

Keeping minors away from betting apps

  • Lock devices: use passcodes and biometric locks, and do not hand a child a phone that is logged in.
  • Secure payments: do not leave cards saved on shared devices or in app stores.
  • Protect logins: never share betting passwords or codes.
  • Use parental controls: limit app installs and website categories on children’s devices.

Operators check age at sign-up, but the household is the first line of defense.

Talk about it early

Explain that betting is for adults, that the odds favor the house, and that ads and social media can make betting look easier than it is. If a young person has gambled, contact the operator, close any accounts involved and talk with them without blame. The National Problem Gambling Helpline can also help.

❓ Frequently Asked Questions

Can a teen use my account?

No. Using someone else’s account breaks the terms, underage betting is against the law, and the account can be closed. Never let a minor use your login, even for a single bet.

Is the age the same for casinos and online bets?

Sometimes, but not always. Rules can differ by state and by product, so check the age for the exact product on your regulator’s page before you sign up.

Why do sportsbooks ask for my date of birth?

To meet the legal age requirement and to run identity checks. Your date of birth is part of mandatory checks, and a mismatch can hold up verification and payouts.
