Category FraudBy Payment Defender Editorial TeamUpdated July 17, 2026Last reviewed July 17, 2026
What American Express Reason Code F29 Means
American Express reason code F29 applies when the Cardmember disputes a card-not-present charge as fraudulent, such as an online, phone, or mail-order purchase they say they did not authorize.
Why This Chargeback Happens
This dispute commonly occurs after third-party fraud on card-absent orders, when a Cardmember does not recognize a descriptor, or when a household member used the Card without the Cardmember's knowledge.
What the Cardholder or Issuer Is Claiming
The Cardmember is claiming the card-not-present charge was not authorized by the legitimate account holder.
What Merchants Should Review
Review order authentication, AVS results, device and IP data, delivery confirmation, and prior undisputed activity. Confirm the verification steps taken and whether the order aligns with legitimate account behavior.
Recommended Chargeback Evidence
- AVS and verification results from the authorization
- Device, IP, and order data linking the customer to the purchase
- Delivery confirmation to the verified Cardmember address
- Evidence of prior undisputed purchases from the same account
How to Prevent Similar Disputes
Merchants may reduce these disputes by using strong verification for card-absent orders, screening high-risk transactions, keeping descriptors recognizable, and responding quickly to fraud notifications before disputes are filed.
