Preventing Fraud-Related Chargebacks In E-Commerce
Last Updated on October 26, 2026 by Dimitri Akhrin
Online sellers face a risk that store counters rarely see. When a card isn’t present, it’s harder to prove who made the purchase. As a result, fraud-related chargebacks hit eCommerce merchants harder than almost anyone else. You lose the sale, the product and the shipping cost. Often, you pay a dispute fee too.
This guide explains the two types of fraud behind these disputes, how to prevent them at checkout and how to win the ones that still get through.
TL;DR
- Fraud claims are common. Mastercard’s 2025 report says cardholders flag nearly half of chargebacks as fraud.
- Two types matter. Stolen-card fraud and friendly fraud need different defenses.
- Prevent at checkout. Use AVS, CVV, 3-D Secure and velocity checks for online orders.
- Capture order data. Device ID, IP address and delivery proof help you win disputes later.
- Respond fast. Instant alerts and a reason-code checklist keep you inside every deadline.
What Are Fraud-Related Chargebacks?
A chargeback happens when a cardholder asks their bank to reverse a charge. When the cardholder says they didn’t authorize the purchase, the dispute counts as fraud. These claims usually come from one of two sources.
Third-Party Fraud
A criminal uses stolen card details to place an order on your site. Later, the real cardholder sees the charge and disputes it. In this case, the claim is valid, so your best defense is stopping the order before it ships.
Friendly Fraud
Here, the real cardholder makes the purchase and later disputes it anyway. Sometimes they forget the order or don’t recognize your store name. Other times, they want to keep the item and get their money back. Either way, the dispute often arrives labeled as fraud.
The cost of fraud-related chargebacks adds up fast. In fact, Mastercard expects global chargeback costs for merchants to reach $42 billion by 2028. Learn more about how chargebacks affect business owners.
How to Prevent Fraud-Related Chargebacks at Checkout
Online orders give you fewer ways to confirm the buyer. Fortunately, several tools close that gap:
- Address Verification Service (AVS): Checks the billing address against the card issuer’s records.
- CVV checks: Requires the security code from the card.
- 3-D Secure: Lets the card issuer verify the buyer, often in the background. In many cases, it can also shift liability for fraud chargebacks to the issuer.
- Velocity checks: Flags many orders or card attempts in a short time.
- Manual review: Holds large or unusual orders for a quick look before shipping.
Watch for warning signs too. For example, look for mismatched billing and shipping addresses, rush shipping on a first order or several cards tried on one checkout. See these fraud prevention signals that predict chargebacks.
How to Stop Friendly Fraud Before It Becomes a Chargeback
Friendly fraud is harder to block at checkout, since the real cardholder places the order. Instead, focus on clarity and proof:
- Use a clear billing descriptor that matches your store name.
- Send order and shipping confirmations with tracking numbers.
- Require a signature on high-value deliveries.
- Make refunds and returns easy to find so customers contact you before their bank.
- Save order data, including IP address, device ID, account login and delivery address.
That last step matters more than ever. Under Visa’s Compelling Evidence 3.0, you can fight certain card-not-present fraud disputes with two earlier undisputed orders from the same customer. Those orders must share at least two matching details, such as IP address or device ID. Visa notes that merchants can share this evidence before a dispute through Verifi’s Order Insight or later through their acquirer.
How to Win Fraud-Related Chargebacks When Prevention Fails
Even with strong prevention, some fraud-related chargebacks will still arrive. When they do, two things decide the outcome: speed and the right evidence.
Respond Before the Deadline
Response windows vary by card network and dispute type. If you find out late, you may lose a dispute you could have won. So set up instant alerts and act on day one.
Match Your Evidence to the Reason Code
Each chargeback comes with a reason code. That code tells you what the bank needs to see. For a fraud claim, strong evidence often includes AVS and CVV results plus the customer’s IP address and device data. Delivery confirmation and past undisputed orders also help. Sending the wrong documents is one of the most common reasons merchants lose.
Build a Response Kit
Keep a simple template for your most common reason codes. Then fill it in with order details each time. This saves time and keeps every response consistent.

Frequently Asked Questions
What are fraud-related chargebacks?
They’re disputes where the cardholder claims they didn’t authorize the purchase. They can come from stolen-card fraud or from friendly fraud.
Why are eCommerce stores hit harder?
Online orders are card-not-present, so it’s harder to prove who made the purchase. That makes fraud claims easier to file and harder to fight.
Does 3-D Secure stop chargebacks?
It helps. 3-D Secure verifies the buyer and, in many cases, can shift liability for fraud chargebacks to the issuer. It doesn’t stop every dispute type.
What evidence helps win a fraud chargeback?
Useful evidence includes AVS and CVV results, IP address, device ID, delivery proof and past undisputed orders from the same customer.
