Chargeback Reason Code 4837

Introduction to Chargeback Reason Code 4837

Chargeback Reason Code 4837, also known as “No Cardholder Authorization,” is issued when a cardholder disputes a transaction, claiming they did not authorize it. This code is assigned by Mastercard and is used primarily for fraud-related disputes. For businesses, managing these chargebacks effectively is crucial to avoid financial losses and protect customer relationships.

Causes of Reason Code 4837 Chargebacks

Chargeback Reason Code 4837 can arise from several scenarios:

1. Merchant Error

• Improper Authorization: Transactions processed without proper authorization are a major cause of these chargebacks. Card-not-present (CNP) transactions, in particular, are vulnerable. Data from Checkout.com shows that over 75% of chargebacks stem from CNP transactions.
• Unclear Billing Descriptors: If the billing descriptor on a statement is not easily recognizable, customers may dispute the charge. Stripe.com reports that 15% of chargebacks are due to unclear descriptors.

1. True Fraud

• Stolen Payment Credentials: When a fraudster uses stolen card information, the result is a chargeback. Mastercard data indicates that fraud accounts for up to 20% of chargebacks under this code.
• Account Takeover: Unauthorized access to a cardholder’s account can result in fraudulent transactions and chargebacks.

1. Friendly Fraud

• Family Members Making Unauthorized Purchases: This is common in households where multiple people have access to the same account. Braintree.com suggests that friendly fraud constitutes about 40% of all chargebacks, many under Reason Code 4837.
• Unrecognized Charges: Cardholders might not remember making a purchase, leading to a dispute.

The Chargeback Process for Reason Code 4837

The chargeback process under Reason Code 4837 follows these steps:

1. Chargeback Filing:

• The cardholder files a dispute, claiming the transaction was unauthorized.
• The issuing bank assigns Reason Code 4837 and notifies the merchant.

2. Merchant Response:

• Merchants have 45 days to respond to the chargeback with evidence that the transaction was authorized.

3. Evidence Required:

• Proof of Authorization: This includes signed receipts, delivery confirmation, or evidence that the cardholder authorized the transaction.
• Transaction Modifiers: Additional evidence may be required depending on the transaction type, such as SecureCode authentication for e-commerce transactions.

4. Final Resolution:

• If the merchant’s evidence is sufficient, the chargeback is reversed. If not, the chargeback stands, resulting in a financial loss for the merchant.

Preventing Chargeback Reason Code 4837

Prevention strategies can significantly reduce the risk of Reason Code 4837 chargebacks:

1. Use Secure Authentication Tools:

• SecureCode: This tool helps verify cardholder identity during online transactions. Checkout.com reports that using SecureCode can reduce fraud-related chargebacks by 25%.
• CVC2 and AVS: These tools verify the card’s security code and billing address, preventing unauthorized transactions.

1. Implement Clear Billing Descriptors:

• Ensuring billing descriptors are easily recognizable can prevent disputes. Stripe.com data shows that clear descriptors reduce the likelihood of chargebacks by 30%.

1. Training and Procedures:

• Proper training on transaction processing and authorization protocols is essential. Merchants should verify account numbers for phone transactions and use correct transaction codes for CNP transactions.

1. Utilize EMV Chip Technology:

• EMV-enabled terminals for in-person transactions help prevent card-present fraud, reducing the risk of chargebacks.

Disputing Chargeback Reason Code 4837

When disputing a chargeback under Reason Code 4837, quick action and proper documentation are key.

1. Types of Evidence:

• Signed Receipts: For in-person transactions, a signed receipt is crucial.
• Delivery Confirmation: For physical goods, proof of delivery can confirm that the cardholder received the items.
• SecureCode Authentication: For online transactions, using SecureCode can shift liability to the issuer.

2. Transaction Modifiers:

• Specific modifiers dictate the type of evidence required. For example, transactions labeled “CNP Airline Transaction” may require proof of a flight manifest.

3. Timing is Crucial:

• Merchants must submit evidence within the 45-day window. Delays can result in an automatic loss of the dispute.

Case Studies and Examples

Real-world examples offer insights into how chargeback disputes are managed:

1. Example 1: Card-Not-Present Fraud

• A merchant faced a chargeback for an online purchase. The cardholder claimed the transaction was unauthorized. The merchant, using SecureCode, provided proof that the cardholder completed the transaction with a verified password. The chargeback was reversed.

1. Example 2: Friendly Fraud

• A cardholder disputed a charge made by a family member without permission. The merchant provided delivery confirmation, but the chargeback was upheld, illustrating the challenges of combating friendly fraud.
