Visa Merchant Screening Service (VMSS)

Visa Merchant Screening Service, or VMSS, is a Visa-operated screening service that helps acquiring banks identify potentially high-risk, unreliable, or fraudulent merchants and third-party agents before onboarding them.

‍

It provides access to Visa’s Terminated Listing Database, which contains information submitted by acquirers about merchants and agents that were terminated for reasons meeting Visa’s listing criteria.

‍

Acquirers use VMSS during merchant and third-party agent due diligence to determine whether a prospective applicant may have previously been terminated by another acquiring institution.

‍

The service covers merchants, sponsored merchants, and third-party agents such as payment facilitators, marketplaces, staged digital wallet operators, and independent sales organizations.

How Visa Merchant Screening Service Works

‍

VMSS supports two primary functions: termination management and termination inquiries.

‍

Through termination management, an acquirer adds a terminated merchant or third-party agent to Visa’s Terminated Listing Database when the applicable VMSS listing criteria are met.

‍

Visa states that qualifying entities must be added within one business day after termination.

‍

Through a termination inquiry, an acquirer searches the database before onboarding a prospective merchant or agent. The inquiry helps determine whether the applicant may match an entity previously terminated by another acquirer.

‍

VMSS also alerts acquirers when a newly added terminated listing retroactively matches an inquiry they submitted during the previous 180 days.

‍

This allows an acquirer to reconsider a merchant or agent that may already have entered its portfolio.

‍

‍

‍

What Happens When VMSS Returns a Possible Match?

‍

A possible VMSS match is a risk signal, not an automatic rejection decision.

‍

Visa requires the acquiring institution to verify that the entity returned by the service is the same merchant or agent being evaluated.

‍

The acquirer must then contact the institution that submitted the listing to understand why the entity was added.

‍

The final onboarding decision should be based on further investigation.

‍

Visa specifies that information from the Terminated Listing Database should be used as an informational tool within the acquirer’s broader decision-making process.

‍

This distinction is important because similar business names, addresses, owners, or other identifiers may produce potential matches that require human review.

‍

An acquirer should not treat an unverified result as conclusive proof that an applicant is prohibited or fraudulent.

‍

Why VMSS Matters for Acquirers

‍

Merchant risk can follow a business as it moves between payment providers. Without shared termination information, a merchant removed by one institution could apply to another without disclosing its previous history.

‍

VMSS helps reduce this information gap by allowing Visa acquirers to:

‍

• Identify merchants and agents previously terminated by other acquirers

‍

• Strengthen merchant and third-party agent due diligence

‍

• Investigate potential fraud, illegal activity, or reliability concerns before approval

‍

• Reduce exposure to unfunded chargebacks and transaction laundering

‍

• Protect against card-brand damage and non-compliance assessments

‍

• Reassess prior inquiries when a retroactive match is identified

‍

Visa states that acquirer participation in VMSS is required under the Visa Rules unless participation is prohibited by applicable law or regulation.

‍

VMSS Is One Part of Merchant Due Diligence

‍

A VMSS search does not replace a complete merchant underwriting process.

‍

The database is focused on previously terminated entities and may not identify a newly created fraudulent business, an undisclosed related entity, or a legitimate merchant whose business model has changed since onboarding.

‍

Acquirers should evaluate VMSS results alongside other merchant-risk controls, including business verification, beneficial ownership checks, sanctions and watchlist screening, website and product analysis, merchant category validation, transaction-risk assessment, and ongoing merchant monitoring.

‍

VMSS helps answer whether Visa’s records contain relevant termination history.

‍

Broader underwriting and monitoring controls are still required to determine what the merchant currently does, whether its application information is accurate, and whether its activity remains within the acquirer’s risk appetite.
