It depends on the type of gambling you want to enjoy. Here is a quick rundown of the minimum ages for all forms of gambling in MO:

How Do I Verify My Gambling Age in Missouri?

You will have to verify your age to sign up and use each of the online sportsbooks listed above now that sports betting is legal in Missouri. Thankfully, this is a fairly painless process as you will usually just need to submit personal information as well as your social security number via a verification link, and then your account should be swiftly verified.

However, in certain instances, there may be further documentation required. This means that you might have to submit the following verification documents:

  • Proof of identity: A valid government-issued photo ID.
  • Proof of address: A recent utility bill, bank statement, or similar document showing your current residential address
  • A recent selfie: Used to match your face to the ID and prevent fraudulent account creation

These requirements are standard across regulated markets and ensure compliance with Missouri’s age, security, and responsible gambling rules.

Identification Accepted for Age Verification

All Missouri sports betting sites and online casinos are legally required to verify that all players meet the minimum gambling age of 21. To do this, they only accept valid, government-issued identification that clearly shows a person’s name, photograph, and date of birth.

The following forms of ID are commonly accepted in MO:

  1. State-Issued Driver’s License or Identification Card: Issued by Missouri or any other U.S. state or territory and must be current and not expired.
  2. U.S. Passport or Passport Card: Must be unaltered and valid.
  3. U.S. Military ID: Active-duty, reserve, retired, or dependent military IDs are typically accepted. It must include a photo and date of birth.
  4. Permanent Resident Card (Green Card): Accepted for lawful permanent residents as valid proof of age and identity.

IDs Not Accepted

Most betting sites in Missouri do not accept the following for age verification:

  • Temporary paper licenses without a photo
  • College or university IDs
  • Workplace IDs or badges
  • Birth certificates (no photo)
  • Student passports for minors

If a player presents an ID that is damaged, expired, or appears altered, the sportsbook can legally refuse service.

Why Is There a Minimum Gambling Age Law?

Minimum gambling age laws are set in place to ensure that wagering takes place in a controlled and responsible environment. They help prevent underage individuals, who are statistically more vulnerable to risk-taking behaviours and problem gambling, from accessing real-money betting products. By setting a firm age threshold, regulators create a safeguard that aligns with broader public-health and consumer-protection standards.

These age requirements also support market integrity. Licensed operators must verify a customer’s age and identity before allowing them to wager, reducing the risk of fraud, financial abuse, and unauthorized account activity. Establishing a clear minimum age ensures that gambling remains limited to adults capable of understanding the financial and legal implications of betting.
