U.S. gambling age verification: Compliance, risks, and 2025 tips

The rise of online gambling

The U.S. gaming industry has earned overwhelming recognition as a growing, value-adding segment of the economy. In fact, 85% of Americans now acknowledge the casino gaming industry as a growth driver, while 76% believe it has a positive impact on the U.S. economy, according to the latest American Gaming Association report. As participation rises across sectors — from sports betting and iGaming to physical casinos — the opportunity for economic contribution grows, but so too do the challenges around responsible gambling.

As interest and participation rise across all verticals — from sports betting and iGaming to land-based casinos — so does the urgency to balance growth with responsibility.

This responsibility begins with regulatory compliance, particularly in age verification. As online gambling becomes more accessible due to mobile platforms and consumer demand, ensuring only eligible participants gain access is no longer just a checkbox on a compliance form — it’s fundamental to preserving trust, mitigating fraud, and shielding underage or vulnerable users from harm.

Federal regulations provide the backbone of online gambling governance. The Wire Act of 1961 remains a foundational law, prohibiting the transmission of bets and wagers via wire communication for sporting events. Although traditionally applied to sports betting, its implications continue to shape the digital gambling environment. Meanwhile, the Unlawful Internet Gambling Enforcement Act (UIGEA) of 2006 reinforces the legal framework by prohibiting gambling businesses from accepting payments connected to illegal online gambling. While UIGEA doesn’t directly address age requirements, it emphasizes the need to comply with state-level laws, many of which include strict age verification mandates.

Amid these federal statutes lies a fragmented landscape of state-by-state gambling laws and rapidly shifting compliance standards.

Let’s explore in this blog how Veriff helps gaming operators navigate this complex regulatory landscape, implement best-in-class age verification, and build safer, more trusted experiences for players.

Why age verification matters

The rise in online gambling has prompted lawmakers to set stringent age verification measures. The stakes are high, as allowing minors to gamble can lead to legal repercussions for operators, tarnished brand reputation, and societal harm. Regulatory bodies across the US have thus mandated online gambling platforms to implement effective solutions to verify users’ ages before accessing gambling services.

The U.S. age verification landscape: Fragmented and fast-evolving

In the United States, age verification laws for online gambling are primarily determined at the state level, leading to variations in legal requirements across the country. However, several overarching trends and regulations have emerged to ensure the protection of minors and promote responsible gambling practices.

State-specific age requirements:

Minimum age variations: The legal age for gambling varies by state and type of gambling activity. For instance, while many states set the minimum age at 21 for casino gambling, others allow individuals aged 18 to participate in certain forms of gambling, such as lotteries or pari-mutuel betting. Operators and players must be aware of their respective states’ specific age requirements. For this purpose, we would like to provide a few examples of state-specific age requirements that gambling businesses need to be aware of:

Strict 21+ enforcement states

Certain states mandate that users must be at least 21 years old to participate in most forms of online gambling:

• New Jersey, Pennsylvania, Michigan

These states enforce a strict 21+ age requirement for all online gambling activities. Advanced security measures like advanced identity verification measures and geolocation verification are used to confirm user identity and location, especially in states like New Jersey.

18+ exceptions and nuanced access

While 21+ is the standard in many states, some allow younger players in specific contexts:

Montana and Rhode Island

• Individuals 18 and older can engage in certain gambling activities, such as lotteries and charitable games, depending on the venue and regulations.

Ohio

• Casinos: 21+ for slots and table games at commercial casinos and racinos
• Lottery, Pari-Mutuel Betting, Charitable Bingo: Open to those 18+
  Ohio maintains clear age boundaries, offering a broad range of legal gambling activities for both age groups.

Texas

• Tribal Casinos: Limited, typically require 21+
• Lottery, Pari-Mutuel Betting, Charitable Bingo: Accessible to those 18+
  Texas restricts most gambling, with only a few legal pathways available for those meeting the minimum age.

New York

• Casinos: Mostly 21+, but some allow entry at 18 if alcohol isn’t served
• Sports Betting: Legal for those 21+
• Lottery, Pari-Mutuel Betting, Charitable Bingo: Open to players 18+
  New York provides a wide array of gambling options, with age thresholds depending on venue and activity type.
  

Massachusetts

• Casinos and Sports Betting: Require 21+
• Lottery, Pari-Mutuel Betting, Charitable Bingo: Available to individuals 18+. The state offers comprehensive gambling access with age limits tailored to specific activities.
  

Prohibited states

Utah

Gambling in Utah is not just prohibited—it’s criminalized at multiple levels. The state has one of the most uncompromising stances on gambling in the United States. Under Utah Criminal Code § 76-10-1102, all forms of gambling are illegal, whether conducted online or offline, and regardless of verification systems or regulatory frameworks applied elsewhere.

This is particularly significant because gambling offenses are embedded in the Utah Criminal Code, not just administrative or regulatory law. This means that violations are prosecuted as criminal acts, and individuals involved can face severe legal consequences:

• Engaging in gambling is classified as a class B misdemeanor.
• Possessing or transferring gambling records can elevate the offense to a class A misdemeanor.
• Operating a gambling enterprise—even facilitating access to gambling services—can be charged as a third-degree felony, which carries more severe penalties including potential prison time.

What makes Utah’s approach especially notable is its zero tolerance. Unlike other states that carve out exceptions for charitable gambling, social gaming, or heavily regulated online platforms, Utah forbids all of it. Even offering a gambling platform or service to someone within the state could expose operators to felony charges.

For any business or digital platform operating in the identity verification or fintech space, understanding Utah’s strict anti-gambling stance is critical—compliance isn’t just a best practice, it’s a legal imperative.

Tools of the trade: Veriff’s compliance-first age assurance suite

Age assurance involves methods to ensure that users accessing online content, services, or platforms meet the appropriate age requirements. It consists of two main approaches: age estimation and age verification. 

Age estimation uses passive data signals, such as behavioral patterns, device data, and technologies like behavioral biometrics or voice and facial analysis, to predict a user’s age without extensive data collection or privacy infringement. 

On the other hand, age verification relies on official documents, biometric checks, or database records (e.g., credit bureaus) to confirm a user’s age, ensuring compliance with age-restricted services. Innovative solutions, like real-time facial analysis, further enhance age assurance by providing accurate predictions and validation without requiring document uploads.
