When Visa Reason Code 10.5 Appears: Real-World Scenarios




Visa Reason Code 10.5 specifically addresses fraud in card - not - present (CNP) environments, which primarily includes online, mail, and phone orders.

Understanding the diverse situations that trigger this code is crucial for effective chargeback defense.

Each situation demands a slightly different approach to gathering evidence, emphasizing that a one - size - fits - all' strategy for CNP fraud prevention is rarely effective.

Scenario

What Happened

Why Code Triggered

Defense Strategy Key

Stolen Card Online Purchase

A fraudster uses stolen credit card details to make an online purchase from the merchant's e - commerce store.

Cardholder reports an unauthorized transaction for an online purchase they did not make.

Provide compelling evidence of transaction security (AVS, CVV, 3 D Secure) and non - delivery to the cardholder.

Account Takeover (ATO)

A fraudster gains access to a customer's online account, changes the shipping address, and places an order using the stored payment method.

Legitimate cardholder discovers unauthorized purchases made from their compromised account.

Show IP address/device ID mismatch, login history, and shipping address change; prove account activity differs from usual.

Friendly Fraud (Family Member)

A family member (e.g., child) makes an online purchase without the cardholder's direct permission, or the cardholder forgets a purchase.

Cardholder disputes the charge, claiming it was unauthorized, even if a household member made it.

Present proof of delivery to the cardholder's address, digital order confirmation, and any prior transaction history with that card.

Digital Goods/Services Fraud

Fraudster purchases non - physical items like software licenses, gift cards, or streaming subscriptions using stolen card details.

Cardholder reports unauthorized charges for digital products they never received or intended to purchase.

Document IP address, email address, download/access logs, service activation details, and usage patterns if available.

Subscription Service Abuse

A customer signs up for a free trial with a stolen card, then cancels the card before the first paid billing cycle, disputing the initial charge.

Cardholder claims the initial (or subsequent) subscription charge was unauthorized.

Provide clear terms of service, trial sign - up confirmation, usage logs, and proof of service delivery during the trial period.

Phishing/Scam - Induced Purchase

Cardholder is tricked into revealing card details on a fake website, which a fraudster then uses on the merchant's legitimate site.

Cardholder disputes the charge, stating they never authorized the purchase on the merchant's site.

Focus on transaction security (AVS, CVV, 3 D Secure), IP address, and device data to show the transaction originated from a distinct, possibly foreign, source.




These scenarios highlight the diverse nature of CNP fraud that triggers Visa Reason Code 10.5. Merchants must maintain meticulous records and employ robust fraud prevention tools to accurately identify and respond to these varied triggers. A 'one - size - fits - all' approach is rarely effective; instead, tailoring your defense to the specific circumstances of each case is paramount for effective chargeback management.




The Evidence You Must Provide for Visa Reason Code 10.5




Successfully fighting a Visa Reason Code 10.5 chargeback hinges entirely on the quality and relevance of the evidence you provide. Visa's dispute resolution system requires merchants to submit compelling evidence that counters the cardholder's claim of unauthorized activity in a card - not - present environment. Generic responses or insufficient documentation will almost certainly lead to a lost dispute and forfeited revenue. Your goal is to construct a narrative, supported by irrefutable data, that demonstrates the transaction was legitimate and authorized.




Merchants need to understand that the burden of proof often lies with them in CNP fraud cases. Presenting a clear, comprehensive, and well - organized package of evidence significantly increases your chances of winning visa reason code 10.5 disputes. This involves both mandatory documents and additional supporting evidence that strengthens your case against unauthorized transaction claims.




Required Documents (Mandatory)




These documents are generally considered essential for any Visa Reason Code 10.5 dispute. Without them, your chances of winning are significantly reduced. They directly address the core elements of authorization and transaction security in a card - not - present environment.

Document Type

Purpose

Transaction Details

Full transaction record including date, time, amount, product/service description, and merchant descriptor. This establishes the basic facts of the purchase.

AVS Match (Address Verification Service)

Proof that the billing address provided by the customer matched the address on file with the card issuer. A full or partial match indicates authorization.

CVV Match (Card Verification Value)

Confirmation that the 3 or 4-digit security code on the card matched the issuer's records. A CVV match strongly suggests the card was physically present with the user.

IP Address and Geolocation

The IP address from which the order was placed, along with geolocation data if available, to show the transaction originated from a plausible location.

Customer Email Address

The email address provided by the customer at the time of purchase, used for order confirmations and communication.

Order Confirmation

A copy of the digital order confirmation sent to the customer, detailing the purchase and terms.




Supporting Evidence (Strengthens Case)




While the above documents are mandatory, including additional supporting evidence can significantly bolster your chargeback defense, especially when dealing with complex cases or friendly fraud. This evidence helps build a more complete picture of the transaction and customer interaction, making it harder for the cardholder's claim to stand.

Document Type

Purpose

Proof of Delivery (if physical goods)

Tracking numbers, delivery confirmation, recipient signatures, or photographic evidence of delivery to the shipping address. This disproves non - receipt.

Device Fingerprint Data

Information about the device used for the purchase (type, operating system, browser, unique identifiers). Consistency with past orders indicates legitimacy.

Prior Transaction History

Records of previous successful transactions with the same cardholder, card, or shipping address. This suggests a pattern of legitimate business.

3 D Secure Authentication Data

If 3 D Secure (e.g., Visa Secure) was used, evidence of successful authentication shifts liability away from the merchant in many cases.

Customer Communication Records

Emails, chat logs, or call recordings between the merchant and the customer regarding the order, shipping, or service.

Account Login History

For account - based purchases, logs showing login times, IP addresses, and any account changes, useful for defending against account takeover.

Usage Logs (for digital goods/services)

Proof that digital products were downloaded, accessed, or services were utilized by the customer.

Terms of Service Acceptance

Evidence that the customer agreed to your terms and conditions, especially for subscriptions or digital products.




The strength of your evidence package directly correlates with your success rate in fighting Visa Reason Code 10.5. Industry experts consistently advise merchants to meticulously collect and organize all relevant data for every transaction. Presenting a clear, concise, and complete case supported by both mandatory and supporting documents is your best strategy for winning visa reason code 10.5 disputes.
