You typically need to provide clear photos or scans of official documents. They often ask for a photo ID (a passport or driving licence), proof of your address (a recent utility bill or bank statement), and sometimes proof you own the payment method you used. Betninja’s security team looks at these documents in private. Doing this quickly is a smart choice. You must complete it before your first withdrawal, so getting it done early eliminates delays when you want your winnings.
