With Visa’s VAMP program introducing stricter compliance measures, are you prepared to navigate these changes and safeguard your business?
Introduction to VAMP
Visa’s Acquirer Monitoring Program (VAMP) is designed to uphold the integrity of the payment ecosystem by consolidating risk monitoring efforts. Effective April 1, 2025, VAMP will integrate the Visa Fraud Monitoring Program (VFMP) and the Visa Dispute Monitoring Program (VDMP) into a unified framework with stricter thresholds. This consolidation aims to streamline oversight of acquirer and merchant risk, ensuring adherence to high standards of transaction security.
VAMP overview and key dates
- Effective April 1, 2025: VAMP integrates VDMP and VFMP into a unified framework with stricter thresholds.
- Advisory period extension: Originally set for three months, the advisory period will now last until October 1, 2025, giving businesses additional time to adjust without penalties.
- January 1, 2026: Even stricter thresholds will go into effect.
Who VAMP affects
VAMP impacts acquirers and merchants involved in card-absent transactions. Merchants exceeding specified thresholds will be classified as “excessive,” potentially facing fines, heightened scrutiny, or processing restrictions. Understanding these classifications is crucial for businesses to maintain compliance and avoid penalties.
VAMP Ratio and Thresholds
The VAMP ratio is calculated as:
(Fraudulent transactions + non-fraud disputes)/Total settled card-absent transactions
Key components include:
- Fraud data: Sourced from TC40 reports.
- Non-fraud disputes: Include Visa reason codes 11, 12, 13, and TC 15 messages.
- Exclusions: Disputes resolved through Rapid Dispute Resolution (RDR), CDRN, or Compelling Evidence 3.0 (CE 3.0) are excluded.
Enrollment thresholds by region:
- 1.5% (150 bps): US, Canada, Europe, CEMA, and AP regions.
- 0.9% (90 bps): LAC region.
Minimum monthly disputes:
- 1,000 disputes required for enrollment (both merchants and acquirers).
2026 classifications:
- Above standard: 0.3% dispute ratio (new tier for 2026).
- Excessive: 0.9% dispute ratio + minimum 1,000 disputes
New metric: VAMP enumeration ratio
Visa will monitor large-scale card testing attacks (enumeration). Merchants with fewer than 300,000 enumerated transactions are excluded from this metric.
VAMP fees and compliance penalties
- Acquirers above standard: $5 per fraudulent/disputed transaction.
- Acquirers excessive: $10 per transaction.
- Merchants excessive: $10 per transaction.
Grace period: No fees from April to September 2025. Enforcement begins October 1, 2025.
Strategies for compliance
To navigate VAMP’s stringent requirements, merchants should adopt the following strategies:
- Implement robust fraud prevention tools: Utilize Address Verification Service (AVS), Card Verification Value (CVV) validation, and real-time fraud detection systems to identify and prevent fraudulent transactions.
- Enhance dispute resolution processes: Leverage tools like Rapid Dispute Resolution (RDR), Order Insight® (OI), Compelling Evidence 3.0 (CE 3.0), and the Chargeback Dispute Resolution Network (CDRN) to address disputes promptly and effectively.
- Regular monitoring of transaction metrics: Consistently track dispute ratios and transaction trends to ensure they remain below VAMP thresholds.
- Staff education and policy updates: Regularly train staff on fraud prevention techniques and update internal policies to align with VAMP requirements.
Understanding key tools for compliance
Rapid dispute resolution (RDR)
RDR is Visa’s automated resolution tool that allows merchants to pre-authorize refunds for specific dispute conditions. If a dispute matches set rules (e.g., low dollar amount, repeat customer), RDR issues an instant refund—preventing a formal chargeback and keeping your VAMP ratio clean.
How RDR helps reduce VAMP ratio:
- Customisation: Merchants can tailor RDR rules based on amount, region, and product type.
- Automation: Automatically issues refunds for disputes that would lead to chargebacks.
- Prevention: Avoids fees and negative dispute metrics by resolving disputes before they escalate.
Order Insight® (OI)
Developed by Visa-owned Verifi, Order Insight® enables merchants to share transaction details directly with the issuer when a customer questions a charge.
How OI helps reduce VAMP ratio:
- Transparency: Provides product descriptions, shipping data, tracking info, and user activity to issuers.
- Dispute reduction: Reduces “unrecognized transaction” disputes by clarifying transaction details.
- Empowerment: Allows issuers to resolve customer confusion before it becomes a chargeback.
Compelling Evidence 3.0 (CE 3.0)
CE 3.0 is Visa’s enhanced evidence framework that supports merchants in challenging chargebacks for unauthorized transactions under reason code 10.4. To successfully dispute a claim using CE 3.0, a merchant must present:
- At least two prior undisputed transactions using the same card.
- Supporting data such as:
- Matching IP address
- Matching Device ID
- Matching account login ID (email or username)
- Shipping address (if applicable)
How CE 3.0 helps reduce VAMP ratio:
By providing this robust set of proof, CE 3.0 helps merchants prevent fraudulent claims from counting toward their dispute totals. The more unauthorized claims you can successfully challenge, the lower your VAMP ratio will remain.
Chargeback dispute resolution network (CDRN)
CDRN, another solution by Verifi, empowers merchants to resolve disputes in real-time, before they become chargebacks. It connects directly with issuers, providing a chance to respond instantly to pending disputes.
How CDRN helps reduce VAMP ratio:
- Early Detection: CDRN detects disputes as soon as issuers initiate them.
- Real-Time Alerts: Merchants receive notifications, enabling them to act quickly.
- Flexible Resolution: Merchants can choose whether to issue a refund, contact the customer, or supply documentation, depending on the case.
This rapid response capability prevents many disputes from escalating into full chargebacks.
