MasterCard Chargeback Reason Code 4808: Authorization

chargeback reason code 4808Merchants who receive a chargeback for a transaction placed with a Mastercard card may encounter reason code 4808, which indicates an improperly authorized transaction that the cardholder does not believe they should be responsible for paying. The actual underlying cause of this chargeback may be true fraud, friendly fraud, or merchant error. Merchants who believe they have received an invalid chargeback under reason code 4808 may be able to represent the transaction and reverse the chargeback with the right compelling evidence.

What is Mastercard Chargeback Reason Code 4808?

Mastercard chargeback reason code 4808 falls under the “Authorization” category. The shorthand description is “Authorization-Related Chargeback.” The use of this reason code indicates that the merchant did not obtain authorization approval for a transaction, or that the authorization request was sent after the transaction date.

This chargeback is often seen when merchants forcibly submit a declined transaction, or when they swipe a card multiple times after receiving a “decline” response from the initial attempt to obtain authorization approval.

While there may be legitimate issues that prevent an immediate approval, it’s risky to keep running a card until you get the desired response.

What Scenarios Might Lead to This Chargeback?

This reason code attaches to true fraud chargebacks when fraudsters succeed in tricking or convincing merchants to run transactions against stolen cards. It may also be seen with friendly fraud chargebacks when the perpetrator deliberately manipulates the merchant into bypassing the authorization step or ignoring the response codes.

Merchants should always request authorization approval prior to submitting a transaction. If a “decline” or some other ambiguous response is sent, the merchant should ask for an alternate form of payment instead of forcing the transaction through. While most payment systems are designed to stop merchants from running unauthorized transactions, there are ways to bypass these protections. When this happens, the issuer and cardholder have clear grounds to file a chargeback and the merchant has few valid defenses.

Sometimes, emergency situations may impel a merchant to disregard their proper authorization protocols, or the cardholder may plead with the merchant to make an exception because they have no other form of payments.

Merchants may have to rely on their own judgment on how to handle these situations, but they should know that they are leaving themselves vulnerable to fraudulent chargebacks when they make these exceptions.

What are the Important Timeframes?

Mastercard recommends that its cardholders file their dispute within 90 calendar days of placing the transaction. The acquirer and/or merchant have 45 calendar days to respond to this chargeback after it is filed.

How Can Merchants Fight this Chargeback Code?

Merchants can fight this chargeback if the cardholder’s claims are false and the transaction was properly authorized. Your chargeback response should include at least one of the following items:

  • Proof that the transaction was properly authorized and submitted within the allowable time limit.
  • Proof that the transaction was submitted against a valid account number and did not exceed the maximum transaction amount.
  • Evidence showing that the chargeback does not comply with Mastercard’s rules and is therefore invalid.
  • If you have already processed a refund for the transaction in question, provide documentation that proves you have credited the cardholder’s account.

How Can Merchants Prevent this Chargeback Code?

Requesting authorization approval is one of the most important parts of the transaction process. A document “approved” response provides compelling evidence against future dispute claims and confirms that the card has not been reported lost or stolen. While there may be circumstances where merchants are tempted to push through a transaction that did not receive an immediate approval, this is always risky and it is always better to cancel the transaction and ask for an alternative payment method.

The following best practices can help you avoid this kind of chargeback:

  • Always obtain authorization approval for every transaction you process.
  • Always use EMV-enabled payment terminals.
  • Do not force unauthorized transactions to go through.
  • Train your staff on proper transaction processing procedures, especially with respect to handling authorization requests and responses.
