Standing for Know Your Customer, KYC is a procedure that every locally authorized gaming lobby needs to maintain. The KYC has several important goals, including making sure that the casino or its customers do not launder money, that the gamers are legally old enough to gamble, that they reside in Sweden, etc.
KYC sounds like a bit of a bureaucratic headache (and it actually is one) but luckily, it is not that complex to pass. The help desk representatives will walk every player through the process. The KYC has to be passed only once (unless a jackpot is won), it is standard, and takes between 24 to 72 hours. The typical list of documents for the KYC includes a copy of ID, a copy of a utility bill or any other proof of address, and a few other documents.
