All forms of gambling, including bingo, are tightly controlled in the UK, and it is illegal for citizens under 18 to use such sites. Therefore, casino sites will go through various identity checks to prove your age and identity. This also helps prevent fraud and criminals using stolen identities to gamble. \r\rFailure to go through a site’s steps to verify your identity could result in your winnings being frozen from cashing out or being banned entirely. This might involve uploading a scan or photo of your passport, driving licence, or utility bill. This info must also correspond with your chosen payment method as you cannot use someone else’s financial account even if they give you permission.
