MATCH code 1: Account Data Compromise
Official definition and what it means for your removal request.
Definition
An occurrence that results, directly or indirectly, in the unauthorized access to or disclosure of Account data.
What this means in plain language
This code means card or account data was exposed or accessed without authorization—often after a breach, leak, or security gap. In practice, Mastercard is recording that customer payment data tied to your business was compromised in some way, not that you intended harm, but that the incident met their reporting bar.
What you can do
If you were listed under MATCH code 1, you can submit a formal removal request to the PSP or acquirer that added you. They will review your case (cause, remediation, corrective actions) and, if satisfied, can request removal from the MATCH list. We help you draft and submit that request. See MATCH list removal and all MATCH and VMSS reason codes.
Removal guides by PSP
The approach to removal depends on which PSP or acquirer listed you. See our PSP-specific guides:
