What Visa Reason Code 12.7 Means

Visa reason code 12.7 applies when a transaction was authorized using invalid or incorrect data, so the authorization did not accurately reflect the transaction.

Why This Chargeback Happens

This dispute commonly occurs when required data elements were missing or invalid in the authorization request, such as incorrect transaction data that should have caused the authorization to be declined or handled differently.

What the Cardholder or Issuer Is Claiming

The issuer claims the transaction was authorized with invalid data and should not have been completed as processed.

What Merchants Should Review

Review the authorization request data elements, the accuracy of the transaction data submitted, and the terminal or gateway configuration.

Recommended Chargeback Evidence

Authorization records showing the data elements submitted
Documentation that valid data was used for the transaction
Evidence correcting any data configuration error

How to Prevent Similar Disputes

These disputes may be reduced by validating authorization data before submission, keeping terminal and gateway configurations current, and correcting data errors promptly.
