Reason code

American Express reason code FR4 is part of the Immediate Chargeback Program, which allows Amex to initiate chargebacks without requiring the cardholder to file a dispute. This typically applies to merchants operating in high-risk industries or those flagged by Amex for a pattern of problematic transactions.

Under this program, Amex can issue immediate chargebacks for transactions that appear suspicious or non-compliant with card acceptance requirements. It’s designed to proactively protect cardholders and reduce fraud, but it also places greater responsibility on merchants to defend legitimate transactions.

‍

If the transaction was valid and authorized, submit clear documentation to prove it met Amex standards:

• Provide order confirmations, signed receipts, or delivery records
  
  
• Include any AVS/CVV verification or fraud screening results
  
  

‍

If you’re in the Immediate Chargeback Program, adopt proactive practices to minimize risk:

• Ensure every transaction meets Amex acceptance requirements and is fully documented
  
  
• Use fraud prevention tools and maintain consistent communication with your customers
