There are 4 possible reasons why the system will not allow you to withdraw funds from your Betfair account: You have exceeded the daily withdrawal limit. In this case you will have to wait until the next day to request a withdrawal. You have not verified your account. In this case you will need to send a copy of your ID card to confirm your account. You are withdrawing more than you are allowed to. Remember that you specified a maximum deposit and withdrawal amount when you registered, in which case you must request a change in the amount by emailing: soporte.co@betfair.com. The total amount of your bets is not less than 50% of your deposits at the time of withdrawal.
