American Express FR4: Immediate Chargeback Program
An American Express dispute reason code, what it asks you to prove, and what Do The Proof puts in the response.
What this code means
Program chargebacks, no inquiry
The inventory records this row as coming from Stripe's map rather than from Amex's own Regulations, whose whole April 2026 document does not list this code. One other published list still prints it.
What the network says wins it
Transaction records
How the app handles it
Arrives in the app as: Fraudulent
Proof this usually needs
- Customer email
- Billing address
- Shipping address

- Delivery confirmation
- Customer name

What the app cannot collect for you

- 20 days from the inquiry or chargeback notice
Where this comes from
- Stripe, reason code categories Accessed 8 September 2026.
