American Express Compelling Evidence (Merchant Guide)

American Express is notoriously tough on merchants when it comes to chargebacks and disputes initiated by cardholders. 

But Amex does give merchants a defined way to show that certain disputed transactions were legitimate. It’s called compelling evidence, and it can improve your chances of getting a chargeback reversed.

How American Express Uses Compelling Evidence

While merchants have the right to contest any chargeback, Amex says that compelling evidence should only be used if you strongly believe that the customer actually participated in the transaction or benefited from the purchase. 

Compelling evidence documentation supports the merchant’s position that the cardholder:

• Participated in the transaction
• Received the goods or services
• Benefited from the transaction
• Authorized the transaction

The key distinction here is that ordinary transaction records alone don’t always prove these things.

For example, a receipt can prove how much was charged or a tracking number may prove that a package was delivered to a particular address. But neither of these necessarily connects the cardholder to the person who placed the order or received the purchase.

Compelling evidence is designed to establish that connection. 

Now that doesn’t mean that submitting qualifying evidence automatically reverses the chargeback. First, Amex needs to verify whether the documentation satisfies the applicable compelling evidence requirements. If it does, the evidence still needs to be reviewed by the issuer before a final decision is made.

The exact evidence required depends on the chargeback reason and transaction type.

Types of Amex Chargebacks That Allow Compelling Evidence

According the latest version of Amex’s Merchant Regulations, compelling evidence can be used for two primary dispute categories:

• C08: Goods or services not received or only partially received
• F29: Card-not-present (CNP) fraud

The requirements are different for each reason code. And within those categories, there are specific data points and documents that you need to present your chargeback reversal request. 

Compelling evidence isn’t just a broad term to share your side of the story. It’s specific, and you’ll need to satisfy the requirements first before your reversal request is even considered. 

Goods or Services Not Received (C08) Compelling Evidence

C08 applies when the Amex cardholder claims they never received the goods/services that they paid for. Or that the goods/services were only partially received. 

Standard compelling evidence for this chargeback can include:

• Proof the full purchase was actually received
• Proof of delivery to the address that was specified by the cardholder
• A completed work order approved in writing
• Evidence refuting a cancellation or return claim
• Proof that an offsetting credit was already processed

Beyond these supporting elements, Amex allows merchants to submit more specialized compelling evidence for C08 chargebacks for certain categories covered below.

General Goods and Services

For transactions involving goods or services, the merchant can provide evidence that shows a link between the cardholder and the person who received the purchase.

American Express specifically says that photographs and emails can serve as compelling evidence here.

For example, the merchant may have email records showing that the cardholder arranged for another person to receive the goods on their behalf. Or confirmation from the recipient that they received delivery.

Again, you’re not just showing that something reached a particular location. You need to provide evidence that links the recipient to the cardholder. 

Airline and Passenger Transportation

Airlines and other passenger transportation MCCs can provide one of several different forms of evidence, including:

• Boarding pass or passenger manifest
• Frequent flyer or loyalty account connected to the trip
• Related transactions like baggage fees, seat upgrades, or onboard purchases
• An itemized invoice with associated transactions

In this case, it’s tough for a passenger to claim they didn’t authorize the purchase of a flight if you can show that the same cardholder paid for a bag at check-in or received a boarding pass and then boarded the plane. This makes it clear that they actually participated in the transportation service being provided. 

Buy Online, Pick Up in Store

For CNP transactions where the items are collected at the merchant’s location, Amex requires the merchant to show:

• Cardmember’s signature on the pickup form
• Or an authorized third-party’s signature
• Additional proof that the recipient’s identity was verified at pickup

So American Express won’t automatically reverse the chargeback based on a signature alone. You also need to document the identity-verification step (like scanning the customer’s driver’s license). 

Digital Goods and Online Services

If you’re selling digital products that can be accessed online, downloaded, or delivered through an app, you can use one of the following components to serve as compelling evidence in your reversal request:

• IP address used at purchase matches IP address used to download the product
• Email address provided at purchase matches email used to deliver the product
• Cardmember accessed merchant’s website for the digital goods/services after the transaction date

Merchants can also provide a description of the digital product, along with the date and time it was downloaded or accessed.

This is why digital merchants should always retain access and delivery logs rather than exclusively relying on payment receipts. As the strongest evidence may come after the transaction has been approved. 

Card-Not-Present Fraud (F29) Compelling Evidence

The F29 Amex chargeback code means the cardholder denies participating in the transaction altogether. This code explicitly applies to CNP transactions (online, phone, mail order, app-initiated). 

For these reversal requests, Amex offers several potential responses to F29 chargebacks:

• Proof of delivery to the cardmember’s billing address
• Evidence that the address was validated and the goods were shipped there
• Proof that an offsetting credit was issued
• Other qualifying compelling evidence (details below) 

The category-specific scenarios below give merchants additional ways to connect the cardholder to the transaction.

Shipped Goods

You can show that the shipping address used for the disputed transaction matches an address used for an earlier transaction that was undisputed.

This type of compelling evidence is particularly useful when a repeat customer claims they don’t recognize an order. 

Passenger Transportation and Airlines

Airlines and passenger transportation businesses can submit the following compelling evidence for F29 disputes:

• Passenger boarding pass
• Passenger manifest
• Loyalty points earned or redeemed for the trip
• Proof the ticket was received at the cardmember’s billing address
• Passenger name matching one used in a previous undisputed transaction

Again, Amex is looking for more than proof that a reservation simply existed. Compelling evidence needs to connect the passenger or trip the cardholder that’s disputing the charge. 

Ecommerce Transactions

Ecommerce has the most detailed compelling evidence requirements compared to any other Amex chargeback type.

First, the merchant must provide:

• Description of goods or services
• Date and time of purchase
• Date and time the cardmember downloaded, accessed, or received the purchase

Second, the merchant must also prove that the customer completed at least one prior undisputed ecommerce transaction during the 12 month period before the chargeback was processed.

That previous transaction must have the same payment credentials for the same unique customer account.

Merchants need to provide the customer’s name and login information associated with the account, plus at least two of the following matching elements that connect the previous undisputed transaction to the disputed transaction:

• Device ID
• IP address
• Email address used for transaction confirmation
• Proof that the merchant verified the cardmember on its website, app, or platform

Examples of verification include: passwords, prior history involving device ID and IP address, two-factor authentication, Amex AAV response of “Y”, or a CID/CVV verification response of “Y”.

This is obviously a much higher standard than just submitting an invoice and order confirmation, and it’s similar to the requirements for Visa Compelling Evidence 3.0. 

Compelling Evidence for Recurring Billing

American Express has a separate set of F29 requirements for recurring billing chargebacks. To have a chance at winning a reversal request here, you need to provide all of the following information:

• Written authorization for periodic billing
• Cardholder’s name and account login information
• Prior undisputed recurring transaction for the same goods or services
• Use of the same payment credentials and unique account
• Descriptions and timestamps for previous and disputed charged
• Evidence of communication sent to the cardholder about recurring billing

For annual or semi-annual merchant-initiated renewals, you also need to document how you obtained the cardholder’s consent for the upcoming renewal.

This includes:

• Date and time of the renewal notification
• Communication method
• Customer contact information used for the notification

These requirements essentially mean you’re obligated to document recurring billing consent. So while the initial agreement matters, that alone won’t help you with a chargeback if you arne’t continuing to communicate with the customer a year or two down the road. And a general terms and conditions page likely doesn’t address this entire requirement as compelling evidence in Amex’s eyes. 

Compelling Evidence for Search and Advertising Services

There’s also a specialized compelling evidence package for website search or advertising services used to promote consumer products or services. 

In this category, compelling evidence requirements include:

• Legally binding contracts
• Details from the initial advertising setup
• At least two of the following identifiers: purchaser IP address, email, company name, purchaser name
• Proof that the cardholder accessed the website to establish the service
• Evidence that the device and card were used in previous undisputed transactions
• Device, IP address, location, and available device names associated with the account
• Proof the services were received
• Description of the services and the date they were provided

This is one of the most documentation-heavy categories in the entire compelling evidence policy. 

Merchants think that a signed contract is all they need to win their case. But as you can see, it’s only a small part of the required response. 

What Merchants Need in Place to Collect Compelling Evidence Before an Amex Dispute Arrives

The way Amex’s compelling evidence policy is set up, most merchants can’t retroactively retrieve documentation if they don’t have certain data collection systems in place to begin with. 

So if you accept a large volume of CNP Amex transactions and chargebacks have been a problem for your business, you need to have:

• A gateway that retains data like full IP addresses, device IDs, confirmation emails, authentication results, and AVV or CID responses
• Ability to retrieve the necessary records by transaction
• Well-documented shipping history
• Recurring billing records with detailed communication and consent
• Digital logs, download records, and access timestamps
• In-person pickup procedures that document identity verifications

Your exact requirements will obviously vary based on your business type. 

And it’s also worth noting that some of this information might already exist within your gateway, subscription software, fraud management platform or order management system. Your processor may have some of it, too. 

But that information simply existing somewhere is far from being able to access everything you need and organizing it in a way that can quickly be sent to Amex during representment. 

How to Submit a Strong Amex Chargeback Response

Lots of merchants make the mistake of just sending as much information as possible to Amex as part of a chargeback reversal request. But more documentation isn’t always better. 

American Express has a compelling evidence policy in place so that you only need to submit evidence that’s related to your specific chargeback reason with applicable requirements.

For example, if you only need to send 6 pieces of evidence, sending 30 doesn’t improve your chances. Especially if one of those 6 requirements is missing. And even if everything required is submitted, you shouldn’t have the reviewer search through dozens of unrelated screenshots, price lists, or website terms.

The best way to make a strong case is by:

• Responding on time (typically within 20 days)
• Submitting a short written explanation of the situation
• Clearly labeling each supporting document
• Stating how each record supports the reversal request

What you need to understand is that your compelling evidence submission is just the first step. You’re satisfying the minimum requirements that will move your request forward for a reversal consideration. 

Final Thoughts

American Express compelling evidence gives merchants a structured path to challenge legitimate transactions that were disputed as fraud or non-receipt of goods and services. 

But this policy is only useful if you already have the necessary records in place.

You can’t recreate a historical IP address, digital access log, or authentication event after the chargeback comes in. And even if your processor is collecting this information, it’s useless if you can’t access those records before the response deadline. 

This is one of the reasons why Amex disputes are so hard to reverse, as a single missing requirement can get your request thrown out.
