Passing the Know Your Customer Verification is actually not a hard and long process, you can finish it for just a few minutes. The KYC verification will not only prove your identity, but also should prove to you, that the bookmaker is legal and you are not going to face any problems through your betting journey.
There is no other way to prove your identity.
The verification process required not only from William Hill but from every online bookmaker is called KYC Verification, or Know Your Customer. You already know that, after the registration process you should pass the verification, in order to prove your identity and not have any problems with William Hill in the future. It is very easy to fraud from the bookmaker if you did not verify your personal details, so the only way for William Hill to prevent any scammers from joining, is to require personal details verification (KYC Verification), which makes any scamming impossible. But, the problem which not only William Hill faced, but all the online bookmakers, is that online scammers see a lot of potential in this. The bookmaker has a lot to offer to its clients, like the many payment methods and bonus offers, which can literally give you some free money. William Hill is one of the oldest and well-known online bookmakers, with a lot of experience behind its back.
