Reason

The cardholder is claiming that they did not authorize or participate in a transaction that you processed.

Typical causes

• The cardholder has a chip card and someone has made a counterfeit copy of it.
• They made a transaction with a counterfeit card at a non-EMV terminal instead of using a chip reader that can detect fraud.

Prevention steps

• Use only EMV-compatible terminals.
• Always use the proper method of cardholder verification, such as signature, PIN, or other.
• Create an electronic or manual imprint for each transaction, where the cards present.

Reason

The cardholder is claiming that they did not authorize or participate in a transaction that you processed.

Typical causes

The cardholder has a PIN-preferring chip card, but the merchant did not use a chip-reading device to process the transaction or used a chip-reading device that was not PIN compliant.

Prevention steps

• Upgrade to EMV PIN-compliant terminals.
• Always obtain the appropriate Cardholder Verification Method (CVM).
• Take an imprint (either electronic or manual) for every card-present transaction.
• Train staff on the proper handling of terminal issues.

Reason

The cardholder is claiming that they did not authorize or participate in a key-entered or unattended transaction conducted in a card-present environment.

Typical causes

• The merchant did not ensure that the card was either swiped or that the chip was read.
• The merchant did not obtain manual card imprint on a key-entered transaction or a card-not-present transaction was not identified as such.

Prevention steps

• Upgrade to compliant terminals.
• Make sure all card-present transactions are either chip-read or magnetic stripe-read.
• Obtain an imprint or perform additional validation, such as PIN.

Reason

The cardholder did not authorize or participate in a transaction conducted in a card-not-present environment, such as internet, mail-order, phone-order, and others.

Typical causes

• An unauthorized (fraudulent) claim was processed using an invalid or stolen account number.
• The cardholder believes the transaction to be fraudulent due to an unclear or confusing merchant descriptor.

Prevention steps

• Consider using all the tools available, including Visa Secure, card security code (CVV2), and Address Verification Service (AVS).
• Use pre-sale fraud detection service providers that can help verify the cardholder’s identity, detect potential criminal activity, and reduce the risk of accepting unauthorized transaction.
• Use a billing descriptor that is easily recognized by the cardholder.
• Always submit an authorization request, no matter the transaction amount.
• Make sure you differentiate between card-not-present and card-present transactions during clearing by noting internet, phone, or mail orders.

Reason

Visa notified the cardholder’s bank that the Visa Fraud Monitoring Program (VFMP) identified the transaction and the cardholder’s bank has not successfully disputed the transaction under another dispute condition.

Typical causes

For merchants in the Visa Fraud Monitoring Program only, Visa identified a potentially fraudulent transaction and informed the issuer, but the issuer failed to initiate a chargeback under another reason code.

Prevention steps

• Monitor your fraud-to-transaction ratio and take necessary steps to prevent breaching thresholds established by Visa.
• Keep accurate records.

Reason

The merchant did not get authorization for the transaction through an account number listed in the Card Recovery Bulletin.

Typical causes

Prevention steps

• Always send an authorization request before processing a transaction if the amount is above your floor limit.
• Check the Card Recovery Bulletin if the transaction is below your floor limit.

Reason

Authorization request received a Decline response and the merchant completed the transaction.

Typical causes

• The merchant did not request authorization.

Reason

Correct and valid authorization was not obtained by the merchant.

Typical causes

• The merchant did not request authorization.

Prevention steps

• Make sure you send completed transactions to your payment processor within the timeframe specified in your merchant agreement.

Reason

The cardholder is claiming that the converted amount of charge on an international transaction is incorrect.
