The good folks at FanDuel take the “Gamble Responsibly” message very seriously. Verification is necessary to prevent minors from gambling and to detect potential money laundering and fraud.
Every user must upload personal information and documentation as part of the registration process, as is the case with any legally regulated online gambling operator, and why it is so important to only play on legit reputable sites. With well-known and highly-regarded sites like FanDuel, you can feel comfortable knowing that all your data is 100% safe and secure.
