Amex F14: multiple ROCs

F14 means the Card Member says they made one valid purchase with you but deny the additional charges that followed. A ROC is a record of charge. Processors don’t all label F14 the same way, so read the description on your notice.

What F14 means

Amex’s reference guide calls F14 “Multiple ROCs.” A ROC is a record of charge, one card charge on Amex’s books. The Card Member says they did make one valid purchase with you, but they deny taking part in the additional charges you submitted after it.

So it’s a fraud code with a twist: the customer admits they know you. They just say the extra charges weren’t theirs.

Check the label before you answer

F14 is one of the codes where sources disagree. Chase’s processor guide lists F14 as Duplicate Processing. Stripe’s Amex category table uses the name Multiple ROCs for F24 and doesn’t list F14 at all. Amex’s own guide puts Multiple ROCs on F14 and No Card Member Authorization on F24.

Don’t answer the label. Answer the description on your notice. If it says the customer denies extra charges, you’re dealing with the claim on this page, whatever your dashboard calls it.

Time limit

Amex’s guide gives Card Members (Amex’s word for cardholders) up to 120 days from the transaction date to dispute most charges, and processor guides list this fraud code at the same 120 days.

Your side of the clock is short. Amex’s own guide tells merchants to respond within 20 days. If you accept Amex through a processor such as Stripe or Square, the processor sets its own date, often a shorter one. The due date on your notice is the one that counts.

What proof matters

Amex accepts proof that each transaction is a valid charge, or proof that a refund already offsets the disputed one. Each charge has to stand on its own: what it was for, when, and why the same customer is behind it.

The customer has already told you who they are

Most fraud codes start with “I’ve never heard of them.” F14 starts with “one of these is mine.” That admission is useful. The valid first charge ties the customer to your business, and the question narrows to whether the later charges were part of the same relationship, such as add-ons, a balance due or a follow-up visit.

The common mistake

Treating F14 as a duplicate-charge complaint and refunding everything, including charges that were real. Amex’s prevention advice is simple: only submit charges for valid purchases made by the Card Member.
