Mobile sportsbooks require this information for regulatory purposes. Your social security number serves to verify your identity but is also needed for tax forms issued by the sportsbooks if your annual winnings exceed $600.
A photo of your driver's license or legal identification card serves to verify who you are and that you are of legal betting age.
In most legal betting states, you must be at least 21 years old to place a bet at a sportsbook. There are four states, however, where the legal age to bet is 18, including Montana, New Hampshire, Rhode Island and Washington.
Mobile sports betting is only legal in certain states within the U.S. In order to place a bet, you must be physically located within one of those legal states. Enabling your location confirms with the sportsbooks that you are physically located in a legal betting state.
Mobile sportsbooks require your personal information to verify your identity and maintain a safe space for users. In order to protect your information, the sportsbook have encrypted any data provided you provided. Data encryption essentially makes the data unreadable, or unusable, to anyone without the key to view it.
