Amex reason code F14 and how to answer missing signature chargebacks

Amex reason code F14 (Missing Signature) means the American Express Card Member denies taking part in a charge and the merchant did not obtain the Card Member's signature where it was required. It is a card present code, so most online merchants rarely see it, and it is far less common since Amex made signatures optional in many markets.

What Amex reason code F14 means

American Express files F14 when a Card Member says they did not make a charge and the merchant cannot show a signed record of charge. In 2018 Amex made signature capture optional in the United States and several other markets, so many merchants no longer collect signatures at all. Where a signature is still required by your agreement, for example certain high value or manual sales, a missing signature leaves the fraud liability with you. Fraud claims like this often arrive as a chargeback directly, without an inquiry first.

Is F14 relevant for online merchants

Mostly not. Online and phone orders never carry a signature, and card not present fraud on Amex is filed under F29. F14 matters for businesses that also sell in person, such as event sales, showrooms, rentals or hospitality, and for merchants whose agreement still asks for signed receipts.

Typical triggers for an F14 chargeback

  • Staff skipped the signature on a sale where your agreement still required one.
  • A stolen card was used in person and the receipt was not signed.
  • A signed receipt exists but was lost or never stored.
  • The Card Member does not recognize the merchant name on the statement.

Time limits for Amex F14

The Card Member typically has up to 120 days to dispute, although Amex can accept some claims later. Your response window is typically about 20 days from the chargeback notice, and many processors set an earlier internal deadline. In Stripe, follow the evidence due date shown on the dispute.

Evidence that helps with an F14 dispute

  • The signed record of charge, if one exists.
  • Proof the card was read by chip with PIN or contactless, which shows the card was present.
  • A receipt or invoice with the Card Member's name and order details.
  • Proof the Card Member took part, such as ID checked at the counter, a rental agreement or later contact about the purchase.
  • Earlier undisputed charges on the same card at your business.

What to avoid when you respond

  • Do not rely on a statement that the sale looked normal. You need records that link the Card Member to the charge.
  • Do not refund after the chargeback is filed, since the funds are already debited.
  • Do not leave signed receipts in paper boxes you cannot search before the deadline.

How to prevent Amex F14 chargebacks

  • Check your merchant agreement to see when a signature is still required.
  • Store signed receipts digitally and link them to the order record.
  • Use chip and contactless reads for in person sales.
  • Use a clear statement descriptor with your brand name.

How F14 appears in Stripe

Stripe usually shows Amex F14 disputes with the reason fraudulent, and the raw code F14 is always in the network reason code field on the dispute. NoChargeback reads both, gathers the card read method, receipt data and customer history, and fills the matching evidence fields. See Stripe chargeback protection.

Does Amex still require signatures?

In 2018 American Express made signatures optional in the United States and several other markets. Check your merchant agreement, because some sale types may still call for one.
