Understanding the VISA Acquirer Monitoring Program (VAMP) and How It Impacts Your Business
What is the VISA Acquirer Monitoring Program (VAMP)?
VAMP is Visa’s newly consolidated risk management program designed to monitor acquirer and merchant activity with an eye toward both dispute and fraud rates. By uniting VDMP and VFMP into one program, Visa seeks to simplify compliance, make risk monitoring more efficient, and reduce the likelihood of fraud and disputes across the board. In short, VAMP is built to help acquirers and merchants maintain safer, more transparent payment practices.
This program is significant for acquirers, as they are responsible for ensuring that the merchants they work with are compliant with Visa’s standards. VAMP holds acquirers accountable for merchants’ behaviors and pushes for proactive measures to manage and mitigate risk. For merchants, the new program emphasizes the importance of keeping disputes and fraud low to avoid costly fees and strained relationships with their acquirers.
Key Components of VAMP
VAMP integrates two crucial aspects of risk monitoring: chargeback management and fraud prevention. Here’s a closer look at the key components:
- Unified Monitoring: By combining the previously separate VDMP and VFMP, VAMP allows Visa to keep a closer eye on both disputes and fraudulent transactions within the same framework. This change helps ensure faster response times and more comprehensive oversight.
- Acquirer Accountability: Acquirers must monitor the merchants they work with and take proactive measures to address any potential issues. This responsibility includes providing education and support to merchants and intervening if dispute or fraud rates approach dangerous levels.
- Risk Assessment: VAMP leverages data-driven analysis to monitor transaction activity. It focuses on the total number of fraudulent and disputed transactions relative to overall sales, identifying high-risk acquirers and merchants for additional scrutiny.
VAMP’s Functionality and Ratio Thresholds Explained
VAMP’s functionality is deeply rooted in data analysis, with Visa continuously reviewing transaction patterns to detect and address any concerning trends. Here’s how it works in detail:
Data Collection
Visa gathers data on every transaction processed by acquirers, closely monitoring both disputes and instances of fraud. This information helps create a risk profile for each acquirer and merchant, allowing Visa to assess the level of risk and take action when necessary.
VAMP Ratio Calculation
The VAMP ratio is the primary metric used to assess risk. It is calculated by adding the total number of fraudulent and disputed transactions over a specified period and then dividing that total by the number of sales transactions during the same period.
Example Calculation:
Imagine an online clothing store processes 10,000 transactions in a month. If the store experiences 150 fraudulent transactions and 200 disputes, the VAMP ratio would be calculated as:
![\[ \text{Vamp Ratio = }\frac{\text{150 Fraudulent Transactions + 200 Disputes}}{\text{10,000 Total Transactions}} \text{ = 3.5\%} \]](https://durangomerchantservices.com/wp-content/ql-cache/quicklatex.com-7c8a4a41289be2a4239a399d343c1f83_l3.png "Rendered by QuickLaTeX.com")
If this ratio exceeds Visa’s established thresholds, corrective actions are required. For 2026, the VAMP ratio thresholds are:
- Merchants: 0.9%
- Acquirers: 0.3%
These thresholds mean that if a merchant’s VAMP ratio exceeds 0.9% or an acquirer’s VAMP ratio surpasses 0.3%, Visa may step in and take action.
VAMP Enumeration Ratio Explained
The VAMP Enumeration Ratio is a specific metric used within the Visa Acquirer Monitoring Program (VAMP) to identify and address card testing fraud, also known as enumeration fraud. Card testing fraud occurs when bad actors use automated methods to test the validity of stolen or guessed credit card details, often resulting in numerous small transactions to verify which card numbers are active.
How the VAMP Enumeration Ratio Is Calculated
The ratio is determined by dividing the total number of confirmed enumerated (card testing) transactions by the total number of settled transactions over a given period.
![\[ \text{VAMP Enumeration Ratio = }\frac{\text{Number of Confirmed Enumerated Transactions}}{\text{Total Settled Transactions}} \]](https://durangomerchantservices.com/wp-content/ql-cache/quicklatex.com-bf63826a0baaecf87769d50659c75679_l3.png "Rendered by QuickLaTeX.com")
Confirmation of Enumerated Transactions
Visa uses a system called Visa Account Attack Intelligence (VAAI) to confirm which transactions are classified as enumerated or card testing fraud. VAAI is designed to improve the accuracy of identifying fraudulent card testing activities, reducing false positives by 85%, according to Visa. This advanced system helps to ensure that only genuine cases of enumeration fraud are flagged.
Exclusion Threshold
Merchants with fewer than 300,000 enumerated transactions are excluded from VAMP Enumeration Ratio monitoring. This means that only businesses with significant volumes of these types of transactions will be subject to the enumeration ratio requirements under VAMP.
The VAMP Enumeration Ratio is an important metric for monitoring and controlling card testing fraud, helping to protect both merchants and the broader payment ecosystem from malicious activities.
VAMP Fees
- Acquirers – Above Standard $5 per fraudulent or disputed transaction
- Acquirers – Excessive $10 per fraudulent or disputed transaction
- Merchants – Excessive $10 per fraudulent or disputed transaction
Timeline for the Rollout of VAMP Changes
Early 2025:
- Preparations begin in the Visa Europe area for the implementation of the new Visa Acquirer Monitoring Program (VAMP) updates. Acquirers and merchants in Europe start receiving communications and guidelines on the upcoming changes.
March 31, 2025:
- Retirement of Existing Programs: The Visa Dispute Monitoring Program (VDMP) and the Visa Fraud Monitoring Program (VFMP) officially end. This date marks the closure of these programs as Visa shifts toward a unified approach under VAMP.
April 1, 2025:
- Launch of VAMP Updates: The updated VAMP program goes live, beginning in the Visa Europe area, with a rollout to the rest of the world to follow.
- Elimination of Merchant “Above Standard” Threshold: The “above standard” threshold is no longer applied to merchants. However, this threshold remains for acquirers, who must continue to monitor their risk levels.
- Introduction of New Indicator Metric: A new metric is introduced, focusing on total transaction counts and combining all types of disputes—both fraud and non-fraud. The old metrics are phased out as the new system takes effect.
- Shift to Risk-Based Enforcement: Visa emphasizes a risk-based approach to enforcement. This shift focuses on “client flexibility” and acknowledges that different acquirers and merchants have varying levels of risk tolerance.
April 1, 2025 – December 31, 2025:
- Transitional Period: A nine-month transition phase begins, allowing acquirers and merchants time to adapt to the new monitoring and enforcement system. During this period, Visa works closely with acquirers to ensure a smooth transition and provides flexibility as everyone adjusts to the new risk-based enforcement approach.
- Global Rollout: After starting in Visa Europe, the VAMP updates continue to roll out to the rest of the world. This staggered implementation ensures that all regions have adequate time to understand and comply with the updated monitoring framework.
January 1, 2026:
- Full Implementation: The transitional period concludes, and the VAMP updates are fully implemented worldwide. Acquirers and merchants are expected to be in full compliance with the new standards, and Visa’s enforcement measures become more standardized.
This timeline highlights the phased approach Visa is taking to introduce the VAMP updates, emphasizing support and flexibility for businesses as they transition to the new system.
The Trickle-Down Effect: A Real-World Example
To illustrate the impact of VAMP, let’s explore a scenario involving an online clothing store called “Desert Threads.” Desert Threads, based in Cheyenne, has seen explosive growth over the past year, thanks to trendy clothing lines that have gained popularity on social media. As the store’s sales increase, so do customer service issues. Some buyers claim that items never arrived, while others initiate chargebacks after deciding the clothes didn’t quite meet their expectations.
Initially, these disputes seem like minor hiccups. But as the store processes more transactions, the dispute rate begins to climb, crossing into the Above Standard range. This triggers a warning to Desert Threads’ acquirer, who now must take notice. If the situation doesn’t improve and the dispute rate continues to rise, Desert Threads may hit the Excessive threshold, triggering $10 fees for each disputed transaction.
Imagine the effect: If the store has 250 disputed transactions in a single month, that’s $2,500 in fees. The acquirer may pass these costs down to Desert Threads or raise their processing fees to mitigate the risk. Worse yet, the acquirer could consider dropping the store altogether if they feel the risk isn’t worth it. Suddenly, Desert Threads is dealing with higher operating costs, potential damage to its reputation, and a strained relationship with its payment processor. The trickle-down effect is real and can be financially devastating if not managed proactively.
How to Stay Compliant and Minimize Risk
Navigating VAMP requires a proactive approach, both for acquirers and merchants. Here are some strategies to minimize risk:
Best Practices for Acquirers:
- Regularly monitor merchant activity and provide educational resources to help them reduce disputes and fraud.
- Use data analysis to identify high-risk merchants early and offer support to address potential issues before they escalate.
- Stay transparent with merchants about their performance metrics and encourage collaboration to find solutions.
Best Practices for Merchants:
- Invest in top-tier fraud prevention tools to detect suspicious transactions before they become a problem.
- Improve customer service and communication, such as using tracking information for shipped items and making return policies clear and easy to understand.
- Monitor chargebacks and analyze why disputes are occurring to make process improvements.
