The Illinois sports betting age limit is 21. That threshold applies to every legal wager in the state, whether you’re walking up to a sportsbook counter inside a casino or tapping a mobile app from your couch. Betting before you turn 21 means any winnings are forfeited, and you can be fined; using a fake ID to get around the age check can be prosecuted as a felony.
Why the Age Is 21
The 21 rule comes from the Sports Wagering Act, the 2019 law that legalized sports betting in Illinois.1Justia Law. Illinois Code 230 ILCS 45 – Article 25 Sports Wagering Act It matches the age required to gamble in an Illinois casino. The lottery is different: you can buy a lottery ticket at 18. That gap causes some confusion, but sports betting follows the higher casino standard, not the lottery one.
How Sportsbooks Check Your Age
Licensed operators carry the legal responsibility for keeping anyone under 21 out. In person, that means a staff member checking a government-issued photo ID before you enter the wagering area at a casino or a sports facility sportsbook.
Online, verification happens when you register an account. The platform cross-references the name, date of birth, address, and Social Security information you enter against public records. Illinois used to require an in-person registration at a partner casino before you could bet on your phone, but that requirement expired in March 2022. Account creation is now fully remote.
Operators also have to report suspicious activity to the Illinois Gaming Board, and the statute specifically names “using false identification” as something they must flag.2Justia Law. Illinois Code 230 ILCS 45 – Article 25 Sports Wagering Act – Section 25-15 A sportsbook that lets underage bettors slip through risks fines, suspension, or losing its license.
Penalties if You Bet Under 21
The Sports Wagering Act doesn’t spell out its own fine schedule for underage bettors. Instead, it says that where the Act is silent, the Illinois Gambling Act and its rules apply.3Justia Law. Illinois Code 230 ILCS 45 – Article 25 Sports Wagering Act – Section 25-107 Under the Gambling Act, the consequences stack up in a predictable way.
The first hit is the money. Any winnings from a bet placed by someone under 21 are confiscated and forfeited to the state, even if the sportsbook has already paid out. Those forfeited funds go to the Education Assistance Fund. You can’t quietly cash a winning ticket and walk away.
On top of forfeiture, civil fines apply, and they escalate with each offense:
- First violation: $50 fine.
- Second violation: $100 fine.
- Third or later violation: $150 fine, 40 hours of community service, and a mandatory gambling evaluation and counseling.
The dollar amounts are small. The third-offense package is the more serious signal: at that point Illinois treats repeat underage gambling as a behavioral issue, not just a rule broken.
Fake IDs Change the Picture Entirely
If you use fraudulent identification to bet before you’re 21, you leave the world of small civil fines and enter felony territory. Presenting a fake ID to place a sports bet can be charged under Illinois’s identity theft statute, which makes the production or use of false identification documents a Class 3 felony.4Illinois General Assembly. Illinois Code 720 ILCS 5/16-30 – Identity Theft A Class 3 felony in Illinois carries two to five years in prison.
A second conviction is a Class 2 felony, punishable by three to seven years. And if the ID you use belongs to a real person rather than being a manufactured fake, charges can escalate further under the same identity theft framework that applies to financial fraud. Using someone else’s account or ID to place bets exposes you to that same set of laws.
Other People Who Can’t Bet, Even at 21
Age isn’t the only bar. The Sports Wagering Act defines a group of “covered persons” who are restricted because of their connection to the sports being wagered on: athletes, referees and umpires, team and league personnel, athletic trainers and medical staff who treat players, and family members or close associates of those people.5Justia Law. Illinois Code 230 ILCS 45 – Article 25 Sports Wagering Act – Section 25-10 The restriction is there to keep anyone with inside influence over a game from betting on it.
Anyone on the Illinois Gaming Board’s self-exclusion list is also blocked from placing sports bets. And no operator, regardless of the bettor’s age, can accept wagers on kindergarten through 12th-grade sports events.6Justia Law. Illinois Code 230 ILCS 45 – Article 25 Sports Wagering Act – Section 25-25
If You Need To Stop Betting
Illinois runs a voluntary self-exclusion program that bans you from both casino gambling and sports wagering across the state. Once you enroll, licensed operators have to refuse your bets, and you can’t collect winnings if a bet does slip through.7Illinois Gaming Board.
