Understanding the intricacies of PayPal's chargeback reason codes is essential for merchants who want to defend themselves effectively while keeping their operations running smoothly. This guide unpacks the common reasons for chargebacks, what they entail, and how you might set up robust defenses to mitigate their impact.
PayPal’s dispute system categorizes chargeback reasons that can sometimes seem straightforward and at other times quite ambiguous, leading to confusion among merchants. Here’s a simplified guide to help clarify:
Each of these codes demands specific evidence tailored to the claim. Missing this vital step can significantly jeopardize your position in a dispute. While establishing a solid defense can enhance your chances of a favorable outcome, it's important to remember that no system can ensure success in every situation due to the inherently complex nature of chargebacks.
To stave off chargebacks before they even arise, focus on setting clear policies, enhancing security measures, and leveraging technology effectively:
Safe App provides powerful tools that seamlessly integrate with your PayPal activities, streamlining evidence collection and dispute handling. By automating evidence bundles according to the specific chargeback code, Safe App not only accelerates the response process but also enhances the likelihood of winning disputes, although it’s important to remember that not every dispute can be won.
PayPal uses its own dispute system first, but chargebacks often roll up to card network codes (Visa, Mastercard) if unresolved. The key list includes:
| Reason Code | Description | Common Merchant Scenario |
|---|---|---|
| MERCHANDISE_OR_SERVICE_NOT_RECEIVED | Customer claims no delivery. | "Item shipped but tracking lost in limbo." Proof: Signed PoD or receipt. |
| MERCHANDISE_OR_SERVICE_NOT_AS_DESCRIBED | Product didn't match listing. | "Buyer says 'wrong color' after 'it fit fine' review." Proof: Photos, description match. |
| UNAUTHORISED | Fraud or unauthorized buy. | "Card tested on your Shopify one-click." Proof: IP logs, AVS match, delivery sig. |
| CREDIT_NOT_PROCESSED | Refund promised but missing. | "Partial refund glitch post-return." Proof: Refund ID/transaction record. |
| DUPLICATE_TRANSACTION | Double-charged. | "Recurring sub glitched on signup." Proof: Transaction logs showing one authorization. |
| INCORRECT_AMOUNT | Wrong charge amount. | "Tax calc error on cart abandonment retry." Proof: Invoice vs. receipt breakdown. |
| PAYMENT_BY_OTHER_MEANS | Customer paid differently. | "They Venmo'd but PayPal charged too." Proof: Alternative payment records. |
| CANCELED_RECURRING_BILLING | Charged after cancel. | "Sub forgot to pause." Proof: Cancel confirmation email. |
| UNKNOWN | Catch-all for other issues. | Dig into RFI details for custom defense. |
These codes correspond to card brands like Mastercard's "fraud" or Visa's "83" (CNP fraud). PayPal categorizes, but issuers decide how to handle the chargebacks.
Understanding these codes can help you:
Manual disputes can consume valuable hours that you could spend on growing your business. Safe App automates much of this process and helps you maintain a proactive stance against potential chargebacks. By implementing effective measures and leveraging powerful tools, you can protect your revenue and ensure smoother transactions in your online store.
