What does the "do not honor" credit card message mean?

The "Do Not Honor" message is a generic decline code (often code 05) sent by the card-issuing bank. It indicates that the bank has blocked the transaction for unspecified reasons rather than a specific error like an expired card. Common causes include:

• Suspected fraudulent or unusual activity
• Insufficient funds or reaching the credit limit
• Incorrect CVV or billing address details
• Technical glitches or bank server issues

To resolve this, double-check your card details or contact your bank's customer service to authorize the payment.
