There are a number of possibilities for why a credit card transaction might not successfully go through during checkout. In most cases, our credit card processing service does not specify the cause for declined charges. We recommend contacting your credit card provider for further information. 


If your payment was declined but you are still seeing a charge on your card, it is probably a pending transaction and will be automatically voided. If you see that charge after 24 hours, contact support@biblio.com and we'll be happy to help.


 The most common reasons for declined payments on Biblio:


Insufficient Funds

A credit card or debit card may be declined due to insufficient funds available in the bank account or credit line.


Billing Address Mismatch

The address you have entered as the billing address during checkout does not match the address that your bank or credit card issuer has on file. 


Card Number Error

Try re-entering the credit card number.  You may have mistyped a portion of the credit card number.


Duplicate Transaction

The transaction submission button may have been pressed too many times, or the first transaction went through successfully and you may have clicked the "Back" button in your browser prematurely. If you are in question as to whether the first transaction went through properly, then email customer support at support@biblio.com.


CCV Mismatch

The Credit Card Verification number may have been entered incorrectly, or not at all. Please check this number and ensure that it has been entered appropriately. The number is usually the last 3 digits under your signature on Mastercard and Visa cards, and the 4 digits on the front right-hand side of American Express cards.
