This doesn’t just apply to casino but to all areas of gambling. If you’re a new customer and you withdraw a large amount of cash, you are going to be asked for ID. Usually, this will be some kind of photo identification like a passport or driving license. In addition, you will also need to provide utility bills to prove your current address.
Yes, it’s absolutely frustrating - digging out all these documents, you may be thinking to yourself why do casinos need all this information? The answer is simple: to prevent online crime and specifically fraud. One of the most common internet crimes is credit card theft and fraud; these very same cards are then used at online casinos. With fraud prevention in place, casinos ensure that your details are protected.
If you are a regular player or expect to play more often, then keep your documents in order and ready to send across; the faster you send in the requested information, the faster you will get your money. And once you have verified yourself with a casino, you shouldn’t be asked for any more documentation.
