Amex reason code C05 is the code for Goods/services canceled. It sits in the Card Member Disputes group. When it lands on your account, the Card Member is saying they canceled the goods or services they ordered. The charge should not stand.

What is Amex reason code C05?

C05 means the Card Member claims they canceled an order for goods or services, but you billed them anyway. It is a dispute about a cancellation, not about fraud or a bad card. The Card Member is not saying the sale was fake. They are saying they called it off first.

The code belongs to the Card Member Disputes group, which holds the codes where the buyer and seller disagree about what happened. That group shapes what proof works. A fraud code wants proof the real cardholder made the purchase. C05 wants proof about the cancellation itself.

If you have never read one of these notices before, start with the guide on how to read a chargeback notice. The code tells you what the Card Member claims, and the claim tells you what to send.

Why a merchant receives a C05 chargeback

A disputed charge is first worked on with the Card Member before the merchant is contacted. American Express tries to settle it with the papers it already has. If that fails, you hear about it.

If more information is needed, the merchant receives either an Inquiry or a Chargeback. An Inquiry arrives when a Card Member disputes a charge that cannot be resolved with the documents on file. A Chargeback means the money has already moved. If the Card Member gives enough information, the merchant's account may be debited upfront.

You get a C05 when the Card Member says they canceled and you still charged them. Common stories behind it:

  • The Card Member called or emailed to cancel, and says you billed them anyway.
  • They canceled a subscription or a recurring service, and the charges kept coming.
  • They canceled an order before it shipped, and the charge went through.

Some of these claims are wrong. The Card Member may have missed your cancellation window, or never canceled at all. That is what your reply is for.

How to respond to a C05 chargeback

The best way to respond is online through your Merchant Account. Do it there rather than by mail, so nothing gets lost.

Your reply has to answer the claim in the code. The Card Member says they canceled. So your proof has to show one of two things: either they never canceled, or their cancellation broke your policy.

A merchant can send its cancellation policy, how it showed that policy to the Card Member, and how the Card Member did not follow it. That is the core of a strong C05 reply. A good reply explains the documents, addresses the specific dispute reason, and describes the steps taken to resolve it.

Keep it short and label everything. A pile of papers with no explanation does not persuade anyone.

Documents needed to win a C05 dispute

Send the papers that speak to the cancellation. That usually means:

  • A copy of the charge record or credit record.
  • Your written cancellation policy, and proof the Card Member saw it. A signed order form, a screenshot of the checkout page, or the terms they clicked all work.
  • Any messages about the cancellation. If they claim they canceled by email, show the email thread. If they claim they called, show your call log with no such call.
  • Proof the goods or services were delivered or used after the claimed cancellation date.

Do not send proof that does not fit the claim. A delivery record alone does not answer a cancellation dispute. It shows the sale happened, not that the cancellation failed.

What happens after you respond

The path depends on what arrived in the first place.

If your reply settles an Inquiry on time, there is no Chargeback. The case ends there, and the money stays put.

After a Chargeback, the merchant can send supporting documents that might reverse it. The Chargeback is undone if your reply addresses the dispute successfully and on time. If you do not reply in time, or you send papers that do not answer the claim, the Chargeback stands.

So the deadline matters as much as the proof. Mark the date the day the notice arrives. For a fuller picture of the rounds that can follow, read what happens after you answer a chargeback.

Two other codes come up near C05, and mixing them up wastes your reply.

C02, credit not processed, is close cousin. There the Card Member says they returned goods or canceled, and you never gave the refund. C05 says the charge should never have happened. C02 says a refund is owed. The proof differs: C02 wants the refund record or the reason no refund was due.

On the Visa side, the matching code is 13.7, canceled merchandise or services. If you take cards on more than one network, know that the same customer story can arrive under different codes with different rules.
