The process that Discover® uses to manage chargebacks is unique and sometimes difficult to master.
The following guide provides an easy-to-understand overview of the card brand’s policies with tips to effectively manage Discover chargebacks and disputes.
Differences Between Discover & Other Card Brands
There are four US-based card brands that facilitate general payment card transactions: Visa®, Mastercard®, American Express®, and Discover.
Of the four, Discover had the smallest percent of transaction volume in 2019.
Discover’s processing volume relates to a few characteristics that make the brand uniquely different from Visa, Matercard, and American Express.
One of the reasons that Discover has a significantly smaller portion of market share is because cards are issued almost exclusively within the U.S. Discover is accepted by merchants in certain international markets, but cardholders don’t have the same global diversity as Visa and Mastercard.
There is another reason for Discover’s limited reach: the brand has a very different networking philosophy than Visa and Mastercard.
Visa and Mastercard connect with cardholders and merchants through a network of partners that act on the brands’ behalf. Issuing banks issue the brands’ cards to cardholders, and acquiring banks process transactions for merchants.
Discover — and American Express — do things differently. Originally, Discover acted independently. The brand issued its own cards directly to cardholders without the help of issuing banks. And Discover processed payments for merchants too.
Recently, Discover made some changes. The card brand still issues cards, but it has expanded to allow certain banks to issue cards on Discover’s behalf. And while the brand continues to process payments, there are some merchants that have the option to run Discover transactions through the same processors that handle their Visa and Mastercard sales.
Historically, all four card brands required issuers to submit a retrieval request before advancing a cardholder dispute to a chargeback. In recent years, Visa and Mastercard have discontinued this practice.
Discover, however, continues to use the retrieval request process. If neither the cardholder nor bank has compelling evidence that supports a chargeback, the issuer is required to first submit a retrieval request.
As a result, Discover issues retrieval requests with greater frequency than the other card brands.
The Discover Chargeback Process
The chargeback process for Discover transactions differs slightly from Mastercard and Visa’s processes. The most notable difference is the use of retrieval requests (see the next section).

Another variable that influences the Discover chargeback process is whether the cardholder obtained the card from the brand directly or via an issuing bank.
If the cardholder obtained a card through a bank, Discover will simply act as a go-between for the issuer and acquirer.

If the card was issued by Discover, then the brand—not a bank—is responsible for initiating the chargeback, reviewing the chargeback response, and assigning liability.

Discover Retrieval Request Reason Codes
If an issuer needs additional information to make a qualified decision about whether or not a chargeback is warranted, the issuer will send you a retrieval request.
The following are Discover’s retrieval request reason codes and examples of evidence that you can send in response.
Reason Code | Dispute Reason | Dispute Explanation | Examples of Evidence for Merchant Response |
---|---|---|---|
01 | Transaction Documentation Request | The cardholder or issuer is requesting information for general purposes. | • Proof that the cardholder agreed to the transaction (for example, a signed transaction document)
• Proof the cardholder received the goods or services • Proof the transaction complied with Discover’s operating regulations |
03 | Transaction Documentation Request Due to Cardholder Dispute | The cardholder or issuer is requesting information because the cardholder claims one of the following: • The transaction was a duplicate • The cardholder doesn’t recognize the transaction • The cardholder was billed after a recurring payment plan expired or was cancelled • The transaction amount was incorrect • The cardholder never received the goods, services, or cash • The cardholder disputes the quality of the goods or services • Credit was due but never issued | • Proof that the cardholder agreed to the transaction (for example, a signed transaction document) • Proof the cardholder received the cash, services, or goods (for example, proof of delivery) • Proof the transaction complied with the merchant’s terms and conditions, including a recurring payment plan if applicable • Proof the transaction complied with Discover’s operating regulations • Proof the merchant has already refunded the cardholder’s account |
04 | Transaction Documentation Request for Fraud Analysis | The issuer is requesting information as part of a fraud investigation. | • Proof that the cardholder agreed to the transaction (for example, a signed transaction document) • Proof the cardholder received the goods or services • Proof the transaction complied with Discover’s operating regulations • Proof the merchant has already refunded the cardholder’s account |
05 | Good Faith Investigation | The issuer or cardholder is requesting information but the deadline to file a chargeback has passed. | • Documents submitted are completely at the merchant’s discretion and are offered on a good faith basis |
It is very important that you respond to every Discover retrieval request that you receive. If you don’t, Discover will likely assess a fee.
Even worse, if you don’t acknowledge a retrieval request, the dispute will automatically advance to a chargeback.
NOTE
Certain retrieval requests will turn into “non-appealable chargebacks” if you don’t respond. This means you won’t be able to fight the chargeback nor recover lost revenue.
Chargebacks with the following reason codes cannot be fought if you didn’t acknowledge the preceding retrieval request.
Discover Chargeback Reason Codes
There are dozens of reasons why cardholders and issuers dispute transactions. Discover uses unique codes to explain those reasons to merchants.
Discover chargeback reason codes are divided into three categories: service disputes, processing errors, and fraud.
Chargeback prevention strategies vary based on the reason for the dispute. And each reason code has unique compelling evidence requirements if you choose to fight.

Discover Chargeback Tools & Resources
Discover offers three brand-specific chargeback prevention tools. Discover’s tools are intended to provide layered protection and be used in conjunction with these common chargeback management tools.
ProtectBuy
ProtectBuy is Discover’s 3D Secure tool. It can help you verify the shopper’s identity and detect fraud before the transaction is authorized.
ProtectBuy compares information provided during checkout with information that Discover has on file for the cardholder (billing address, phone number, email address, etc.). If there is a mismatch or ProtectBuy senses questionable activity, the technology will send a one-time password via text or email for an additional layer of validation.
If the shopper is able to access the password and authenticate the information provided, you can approve the transaction with confidence. If ProtectBuy is unable to verify the shopper’s identity, you will be notified. Then you have the option to approve or decline the transaction.
All cardholders are automatically enrolled in ProtectBuy. If you choose to use this tool, you’ll be able to monitor potential fraud for all Discover transactions.
Verify+
Like ProtectBuy, Verify+ compares information provided during checkout with information that Discover has on file. However, this fraud detection tool works after the transaction has been completed.
If Verify+ detects a mismatch or other questionable activity, the technology will notify you. You then have the option to proceed with the order or cancel it and stop fulfillment.
There are two ways you can receive notifications.
- The standard version is a web based interface.
- The premium version is accessed through an API.
Fraud Alerts
If a cardholder disputes a purchase because of fraud, Discover will notify you immediately via its Fraud Alerts tool. With this information, you can:
- Cancel shipment or call the shipment back if it’s already gone out
- Cancel future charges if the transaction was part of a subscription
- Create a negative list to block any other transactions that may be attempted
There are two ways you can receive these notifications.
- The standard version is a web based interface.
- The premium version is accessed through an API.
NOTE
Discover’s chargeback prevention tools should be used as part of a comprehensive dispute management strategy. The more tools and techniques you use, the better your protection will be. Check out the following resources for additional chargeback prevention information.
