Declines can happen for a variety of reasons. When we submit a charge to your bank, they have automated systems that determine whether or not to accept the charge. These systems take various signals into account, including your spending habits, account balance, and card information like the expiration date and CVC.
These signals are constantly changing, so a previously successful card might be declined in the future. Even if all of the card information is correct, and you've previously made a successful payment, a future charge can still be declined by a bank’s fraud systems.
Finding out more information about a specific decline
We show all the information we receive from your bank about a decline in your dashboard. Unfortunately, most declines are generic, so we don’t have much specific information as to why a charge was declined.
If all of the card information seems correct, it's best to contact your bank, inquire for more information, and ask for future charges to be accepted.
