What Is a Referral Code in Betting? Your Guide to Friend Bonuses

A referral code in the world of online casinos and sports betting is a unique alphanumeric identifier used to enroll new users into a platform’s “refer-a-friend” program. This code, generated by an existing user, is a marketing tool that benefits both parties: the existing user (referrer) and the new user (referred friend) receive a bonus when the friend completes a required action, such as signing up, depositing, and placing a bet.

The key takeaway is that referral codes provide free bonuses like bonus bets, site credit, or free spins. However, a new user should always check if the referral bonus is worth more than the standard welcome offer the sportsbook provides, as the referral code might replace the better bonus.

How Referral Codes Work

Referral programs follow a simple, multi-step process to ensure both the new player’s identity and the qualifying action are verified.

The 4-Step Process

  1. Code Generation: The existing user finds their unique code or sharing link (the preferred method) within the app’s promotions or account section, often labeled “Refer a Friend” or “Earn $$$.”
  2. Signup and Entry: The new player uses the shared link or manually enters the code during the registration or initial deposit process.
  3. Qualifying Action: The friend must meet specific requirements, which always include a minimum deposit (e.g., ) and usually a qualifying wager (e.g., placing a  bet). The friend must also verify their identity and location in a legal betting state.
  4. Reward Distribution: Once the qualifying bet settles (usually within 24 to 72 hours), the platform credits the agreed-upon bonus to both the referrer’s and the referred friend’s accounts.

Rewards and Restrictions

Rewards are typically granted as bonus bets (free wagers where only the winnings are returned, not the stake) or site credit. All bonuses come with strict terms:

  • Wagering Requirements: Bonuses are generally non-withdrawable until they are wagered at least once (1x wagering requirement).
  • Expiration: Bonuses expire quickly, often within 7 to 30 days.
  • Odds Restrictions: Qualifying bets often require minimum odds (e.g., -200 or longer) to prevent users from betting on heavy, low-value favorites.

Referral Examples from Major U.S. Platforms

Referral program structures vary widely among the top legal U.S. sportsbooks and casinos:

BetMGM in bonus bets each minimum deposit and placing a qualifying wager at -200 odds or longer. 20 per month
Caesars Up to in Reward Credits each minimum deposit and wager. 10 total

Benefits and Risks for the New User

While referral codes offer a great way to earn free money, new users must weigh the potential cost.

Benefits

  • Free Bonus: You get bonus funds or credits for an action (signing up/depositing) you would likely do anyway.
  • Social Incentive: It is an easy way to share the fun of betting with friends while earning rewards.

Key Risk: Forfeiting the Welcome Offer

The main risk is that the referral code may override a much more valuable standard welcome bonus.

  • For instance, a sportsbook might offer a massive first-bet safety net to new users, but using a friend’s referral code might only grant a  bonus bet.
  • Best Practice: Always check the app’s current promotions page to compare the value of the referral bonus against the highest standard new user offer available.

User Tips for Maximizing Referral Value

  • Share Links, Not Codes: Use the unique sharing link provided by the app, not the manual code. Links automate the tracking process and prevent common errors like typos during manual entry.
  • Verify Requirements: Confirm the minimum deposit and required odds for the qualifying bet before the friend places their wager. Failure to meet these requirements voids the bonus for both parties.
  • Use in Legal States: Referral programs are only valid when the new user signs up and plays within a state where the platform is legally licensed to operate.
