Before you claim any sportsbook offer, you need to know one thing: your state's minimum betting age. Get it wrong and your account gets closed, your bonus gets voided, and you're out whatever you deposited. Here's the full picture so you can register with confidence.

What is the minimum age to bet on sports in the US?
The majority of legal states set the minimum age at 21, mirroring casino gambling requirements. Sports betting is legal in 39 states plus Washington D.C. and Puerto Rico as of September 2026, and most of those markets follow the 21+ standard. A small number of jurisdictions permit 18+ betting, but that list is shrinking. Kentucky originally launched at 18+ in 2023. In April 2026, the Kentucky legislature passed House Bill 904—overriding the governor's veto—and raised the minimum age. Washington D.C. remains one of the few markets where 18+ sports betting is permitted.
Which states allow 18+ sports betting?
Very few, and the rules can change fast (Kentucky proved that). Even where 18+ is technically legal online, you can still get turned away in person. Retail sportsbook locations attached to alcohol-serving casinos often enforce a 21+ entry policy on-site, regardless of what state law says about online wagering. Always verify with the individual property before making a trip.

Does age affect which bonuses I can claim?
Yes, directly. Every licensed sportsbook verifies your identity at registration. If you're under the required age in your state, you won't complete sign-up, which means no account and no bonus. Welcome bonuses are also limited to one per household, IP address, or device—so there's no workaround. Age requirements vary by state, so confirm your local rules before you start the registration process.

What should I do before registering at a sportsbook?
Confirm your state has legal sports betting. Confirm you meet the minimum age requirement—21+ in most markets, 18+ in a handful. If you're betting at a retail location, call ahead; the on-site policy may be stricter than state law. Enter any promo code at sign-up, not after—most sportsbooks won't apply it retroactively. And review the operator's current terms, since age rules and bonus eligibility can shift with new legislation.
