When you register a new debit or credit card to your LevelUp account we conduct an authorization hold. This is a temporary charge on your account for $1.00, $0.00, or Not Available as a test to ensure this card will function properly with LevelUp. This way, when it comes time for you to make a transaction with LevelUp there are no issues processing the payment.
This authorization hold typically will be removed from your account in 1-5 business days, but it may take up to 30 days depending on the issuing bank. As this is just an authorization, you are not responsible for paying this amount to LevelUp.
Additionally, the amount of the charge varies depending on the bank - LevelUp does not control this.
