There are many reasons why your payment might have failed due in the checkout, however, 95% of the errors are caused by the information being inputted incorrectly and these errors can be rectified easily. Below are the following reasons that make up 95% of why payment may have failed:

1. Billing Address does not match where the card is registered to - please ensure that the Billing Address you have entered in the Checkout matches the address of where the card is registered to.  

2. Billing Address matches where the card is registered to but has been entered incorrectly - please ensure that the Billing Address you have entered had been entered exactly as the bank or card issuer would have it in their database. i.e. the address is in the same format, the address has no more or fewer details in it, the postcode is correct and the spaces are in the correct place.

3. Name on the Billing Address does not match the name on the card - please ensure that the name on the Billing Address matches the name on the card you are using. 

Error Codes: If the following codes are shown on the error message then the issue is with the Billing Address: 10701, 10702, 10703, 10704, 10705, 10706, 10707, 10708, 10709, 10710, 10711, 10712, 10713, 10714, 10715, 10716, 10717, 10718

7. Your bank or card issuer may have blocked the payment - sometime the payment may not go through as your bank or card issuer will not allow the payment to go through for some reason. This may be because:

            a) The delivery address is not recognised by your bank or card issuer. Sometimes if you are delivering goods to a new address or an address that your bank or card issuer does not recognise then they may block the payment for your safety. Error Codes: 10424, 10474, 10477, 10540, 10719, 10720, 10721, 10722, 10723, 10724, 10725, 10726, 10727, 10728, 10729

            b) Insufficient funds. There may be insufficient funds in your bank or on your credit card to complete the transaction, therefore please double-check this. Error Codes: 10321, 13602, 17200

            c) Reached daily spending limit. Most credit and debit cards have a daily spending limit, so please ensure you haven't hit your daily spending limit as this could be a reason for the payment to be blocked. Error Codes: 10553, 10578, 10610, 11091
