The Know Your Customer (KYC) program that new casinos implement includes account verification. It would be best if you answered these questions for the casino to verify your identity. Casinos online ask you to provide some formal paperwork to prove your identity. Passport, government-issued ID, or driving permit are all acceptable forms of identification. Any legitimate bank statement or a copy of a utility bill will serve as proof of residence. These documents are sent to the email address you give when scanned and uploaded to the server. You should capture all papers, and each copy should be readable.
