Yes. While you may wager using PayPal before verifying your account, there will be restrictions on how much you can transfer, receive, and withdraw. This may have an impact on how you fund your account or withdraw any winnings. It is usually preferable to authenticate your account as soon as possible in order to use it without limitations. If you have just got a sportsbook account but no verified payment method, you will not be able to make qualifying bets anywhere in the sports betting industry.
