VMSS code 24: Illegal Transactions
Official definition and what it means for your removal request.
Definition
The Merchant or Third Party Agent submitted unlawful and/or prohibited transactions into the payment system.
What this means in plain language
Payments were submitted for goods or services that Visa considers unlawful or prohibited. The focus is on the nature of what was sold or how it was processed, not a minor policy slip.
What you can do
If you were listed under VMSS code 24, you can submit a formal removal request to the PSP or acquirer that added you. They will review your case and, if satisfied, can request removal from the VMSS list. We help you draft and submit that request. See VMSS removal and all MATCH and VMSS reason codes.
