Troubleshooting | Card Declines

4 min. readlast update: 08.04.2026

If the card on file declines once for a membership payment, and the Student chooses to pay via a separate captured payment with another card or cash, submit a billing change form to reschedule the payment so the card on file is not to be tried again. Go to Services, Bambora Billing, and select "Bambora Submit Billing Changes". 

After five failed payment attempts, Bambora will put the account on hold, and the member must provide a new payment method. Filling out a "Change Credit Card detail" form will fix this.

Bank error code 686 INVLD MER ID

Prepaid debit cards often have several restrictions, such as limited functionality for online or recurring payments, which can vary according to the card issuer’s policies. They do not always work everywhere, which would explain this. Your member may need to consider providing an alternative payment method or contacting their bank to clarify any restrictions associated with this card.


Bank error code 688, bad processing - "Failed Card Verification"

This a general error code that can be caused by a variety of factors, such as:

  • Invalid Zip Code on Member's Profile.
  • Invalid credit card information. This could be due to a typo in the credit card number, expiration date, or CVV code.
  • Insufficient funds: The customer's credit card may not have enough funds to cover the payment.
  • Declined transaction: The customer's bank may have declined the transaction for various reasons, such as fraud prevention or suspected suspicious activity.
  • Technical error: There may be a technical error with the bank's system or the payment processor.

To troubleshoot the problem, you can try the following:

  • Update the Member's Zip Code on their profile. 
  • Check the customer's credit card information carefully. Ensure that all information is correct and that the card has not expired.
  • Ask the customer to try processing the payment again later. If the payment goes through later, a temporary technical issue may have caused the problem.
  • They should contact their bank or payment processor for assistance. They may help identify and resolve the specific cause of the error.

If you are still receiving bank error code 688, bad processing, after trying the above steps, you may need to contact Bambora for further assistance.


Bank error code of 690 "Inv Acct Num"

This means the account number is invalid. The card information is most likely invalid. Try updating the Credit Card information directly in Bambora to see if it is invalid.


Bank error code of 693 or 695

The card has been declined. In this case, they should contact their bank to inquire about the declined card.


Bank error code of 697 - SERV NOT ALLOWED

The card has been declined, and the error code is SERV NOT ALLOWED.

This usually means the customer's credit card company does not allow them to purchase products from your business type. The member must contact the bank to authorize the purchase or switch the card on file.


Bank error code 701, "Please Retry"

This appears when there is trouble connecting to the billing server. It might be that the credit card processing was down for some scheduled maintenance for a portion of the night, impacting payments.

To resolve this, you will go to the member's profile and billing section and select to capture a manual member payment. Then, complete a billing change form to reschedule their next payment so the system doesn't attempt another charge.


If you receive a message that says, "Customer Info failed data validation," the card information is most likely invalid. Try updating the Credit Card information directly in Bambora to see if it is invalid.


Duplicate Request

If you receive this error message, it is likely because the card for another member is already on file. We recommend combining family members under one billing account through the Billing Change Form. If they wish to be billed separately, you must put another card on file.
