How to Withdraw Money. You may withdraw funds from your CashBox Account by requesting a Genie eCheck electronically, requesting a physical check through the mail, or using your Genie Debit Card (eligible Genie Members only). Generally, we will send checks only to a Confirmed Address. We will not send checks to P.O. Boxes. If you would like us to send a check to an address that does not meet these criteria, you must contact Customer Service and provide the documentation that we request to verify your association with the address.
