List of Credit Card Declined Codes – Error Codes Explained

Introduction

This KB article explains why your credit card payment may be declined and what each decline code means. These codes come directly from your bank and usually point to the exact issue. In most cases, you can resolve the problem yourself by checking your card details or contacting your bank.

 

What Is a Credit Card Decline Code?

A credit card decline code is a short message (usually numbers or letters) that appears when a payment cannot be processed. It’s generated by your bank or card issuer and indicates the reason your transaction was stopped, for example, insufficient funds, card restrictions, incorrect details, or a temporary technical issue.

When Should You Contact Us?

Please reach out to us only if:

  • You followed the steps below, and the bank has confirmed everything is working on their end

  • You’re still unable to make a payment

  • If you receive a decline code that does not match our guide

We’ll be happy to look into the issue further once you’ve checked with your bank.

Common Reasons a Card Is Declined

Although each decline code is specific, most issues fall into a few simple categories:

  • Codes 14, 15, 63 - Incorrect card details
    The card number or security code was entered incorrectly. Re-enter your details carefully.

  • Code 54 - Expired or restricted card 
    The card has expired or is no longer valid.

  • Codes 51, 65 - Insufficient funds or credit limit reached
    Your account doesn’t have enough available balance, or the transaction would push you over your credit limit. Check your balance or use an alternative card or payment method.

  • Code 57 -Transaction not allowed
    Online, international, or certain merchant types may be blocked on your card.

  • Code 36 - Restricted card
    The card is restricted by the card issuer.  Contact your bank or card issuer to get more information and to resolve the issue. 

These issues can usually be fixed quickly by checking your card details, paying down your balance, or contacting your bank to remove restrictions.

Fraud-Related Decline Codes

The following codes mean your bank has flagged the card for security reasons:

  • Code 07Card flagged for fraud
    The card has been flagged for possible fraud. Contact your bank or card issuer to confirm the activity and remove the block.

  • Code 41Card reported lost
    The card has been reported lost. Contact your bank or card issuer to confirm the activity and remove the block.

  • Code 43Card reported stolen
    The card has been reported stolen. Contact your bank or card issuer to confirm the activity and remove the block.

  • Code 215 / 534 / 596Suspects fraudulent activity
    Bank or payment provider suspects fraudulent activity. Contact your bank or card issuer to confirm the activity and remove the block.

If you see any of these, contact your bank immediately. For your safety, we cannot override fraud-related blocks.
