You may withdraw a maximum up to $500 in a single day at an ATM or bank teller with most GreenDot cards. The limit may vary depending on the sessions for your specific card; whatever, the Walmart Money Card by GreenDot, for example, follows the $500 per day ATM withdrawal limitation. But offers higher withdrawal limits of up to $1,000 per day at a Walmart register or Money Center and $1,500 per transaction at an attending bank teller.
If you would like to grow your daily ATM withdrawal limit, contact Green Dot's customer service department (866) 795-7597. The total daily spend limit, which includes ATM withdrawals, is $3,000.
