Can i withdraw an overdraft if i have no money in my account?

No, you typically cannot withdraw funds from an overdraft if your account balance is at zero. Overdrafts allow you to borrow money up to a certain limit when your account is overdrawn, but you must have a negative balance to utilize that feature. If your account is already at zero, you'll need to deposit funds before you can access any overdraft. Always check with your bank for specific policies regarding overdraft access.
