American Express chargeback reason codes, in plain English
Amex doesn't use Visa or Mastercard reason codes. It runs its own dispute system with its own code families — C codes for cardmember disputes, F codes for fraud, P codes for processing errors — and if you take Amex through a processor like Stripe, the dispute that lands in your dashboard carries one of these codes. The good news: the underlying stories are the same ones Visa and Mastercard tell. This page translates five common codes, names the evidence that answers each, and points to the Parry guide that covers the situation in depth.
C08 — Goods or services not received
What it means: The cardmember says they paid and the goods or services never arrived — or only part of the order did. It's the Amex counterpart to Visa 13.1 and Mastercard 4855.
Evidence that answers it: For goods, the carrier delivery scan at the checkout address, with timestamp, plus the order confirmation showing that address. For services, dated proof the service happened: deliverables as sent, engagement records, client communications. One structure works for both — summary first, then dated exhibits.

C14 — Paid by other means
What it means: The cardmember says this purchase was paid another way — cash, a different card, a separate invoice — so the Amex charge shouldn't stand. Sometimes that's a genuine double payment; often the "other payment" was for a different order, or never happened.
Evidence that answers it: The Amex transaction record tied to its own order or agreement, and a clear mapping of what any other payment actually covered. If the customer did pay twice for the same thing, the winning move is the refund record for the duplicate, with its reference number. If the other payment belongs to a separate purchase, show both paper trails, side by side.

C28 — Canceled recurring billing
What it means: The cardmember says they canceled the subscription or recurring arrangement, and charges kept coming anyway. The Amex counterpart to Visa 13.2.
Evidence that answers it: The signup terms and cancellation policy as shown when they enrolled, your cancellation records (or evidence no cancellation was ever requested), and — strongest of all — proof of continued use after the date they claim they canceled. If they did cancel and you charged in error, refund the post-cancellation charges and submit that record instead of arguing.

F14 — Multiple records of charge (fraud family)
What it means: F codes are Amex's fraud family. F14 arises when multiple records of charge exist for what the cardmember says was a single transaction — the pattern looks like one purchase billed several times, and Amex treats the extras as unauthorized until shown otherwise.
Evidence that answers it: A per-charge breakdown: each record of charge matched to its own authorization, order, and fulfillment. If each charge bought something distinct, two (or more) complete parallel paper trails answer it. If the extra records really are duplicates of one transaction, refund them and submit the refund records — under a fraud code, a fast honest refund beats a slow argument.

P01 — Unassigned card number (processing error)
What it means: P codes are processing errors. P01 means the charge was posted against a card number Amex can't match to the account it should belong to — a keying, tokenization, or account-updater problem somewhere between checkout and posting. The cardmember may genuinely not recognize the charge because, on their statement, it isn't properly theirs.
Evidence that answers it: Your authorization record showing the card details as presented at checkout and approved, the order record tying that authorization to a real purchase, and any processor trace data connecting the charge to the correct account. If the charge truly posted to the wrong number, coordinate the correction and refund through your processor rather than fighting — P01 is a plumbing problem, not a credibility contest.

The pattern across all five
Whatever the code, the packet shape that works on Amex is the one that works everywhere: a 3–5 sentence summary naming the code and your strongest fact, a dated timeline, and labeled exhibits where every claim points at a document. Amex analysts work from your evidence file, not your store's backend — if a record isn't in the packet, it doesn't exist. And as everywhere: if the customer's claim is actually right, refund fast and document it. No outcome can be guaranteed; the bank always decides.
