American Express F29 chargeback: Card Not Present fraud, and how to win it
Checked
American Express reason code F29, Card Not Present, means the Cardmember says they did not authorize an online, phone or mail order purchase. The issuer must report the fraud first and usually has 120 days to file. It does not apply when the payment was protected by the SafeKey (3-D Secure) liability shift. Win with delivery to a verified address or compelling evidence such as an earlier undisputed purchase on the same card with matching device, IP or email.

What PlatformDTC does
PlatformDTC writes the product description, delivery address, buyer email and IP address onto every Stripe payment at checkout, then adds the carrier and tracking number when the parcel ships. When a fraud dispute opens it stops the subscription behind the order, and its response states the buyer's IP, billing and shipping address, what was bought and that the customer never asked the store for a refund. With "Answer a chargeback automatically" switched on, it sends the response to the bank for you before the deadline.
What it means
The Cardmember says a card-not-present purchase was not theirs. US and Canada issuers cannot use F29 solely because a delivery signature is missing.
Excluded: SafeKey liability shift transactions, some card security code and address verification cases, contactless digital wallet and QR transactions.
Why customers file it
Stolen card details used online, a family member's purchase, or a charge the Cardmember does not recognise.
Evidence that wins
For every Amex code, a credit that directly offsets the disputed charge is also an accepted response.
- A carrier delivery receipt (US and Canada merchants do not need the signature)
- A valid authorization where the card security code (CID) check returned "N" or "U"
- The address was verified in the authorization and the goods shipped there
- Compelling evidence: the shipping address matches an earlier undisputed order
- E-commerce compelling evidence: description, purchase date and time, an undisputed e-commerce purchase on the same card in the prior 12 months with the customer's name and login and two or more matching of device ID, full IP or email, plus your own verification (password, two-factor login, device history or address/CID "Y")
How to prevent it
- Use American Express SafeKey (3-D Secure) on risky payments
- Check the address and card security code
- Refund payments flagged as fraud before a chargeback
For developers
On Stripe the dispute object arrives with reason "fraudulent" and the card network's own code in payment_method_details.card.network_reason_code; listen for charge.dispute.created and read evidence_details.due_by for the deadline.
American Express uses one letter plus two digits for US and Canada merchants; elsewhere it uses four-digit ISO codes, and each letter code sits under one.
Frequently asked questions
- Does Amex need a signature on delivery for F29?
- No. US and Canada merchants do not need the Cardmember's signature on the carrier delivery receipt, and issuers cannot use F29 solely for a missing signature.
- Does SafeKey prevent F29?
- Yes. Transactions covered by the SafeKey liability shift are excluded from F29.
