Visa Reason Code 12.4: Incorrect Account Number
The transaction was processed against the wrong card account number — either because a different account than the one that participated in the sale was charged, or because the account number was recorded incorrectly.
Your strongest argument
Authorization and transaction records confirm the correct account number was captured and charged.
Evidence that wins a Visa 12.4 dispute
- Authorization records confirming the account number submitted matches the card that participated in the sale
- Terminal or payment-system record showing the correct card was captured at the time of the transaction
- Signed receipt or electronic record tying the specific account to the purchase
