Visa
- Visa sets rules and fines merchants for breaking them, but they don't process your payments or issue your cards - your processor and issuing bank do that
- VAMP (Visa Acquirer Monitoring Program) replaced VDMP and VFMP in April 2025; the merchant excessive threshold is 2.2% (tightening to 1.5% in April 2026) with 1,500+ disputes, but processors commonly flag merchants around 0.9%
- Visa Compelling Evidence 3.0 (CE 3.0) allows fraud dispute liability shift if you can prove two prior undisputed transactions from the same device and card
- Visa's chargeback response window is 30 days; missing it means automatic loss regardless of how strong your evidence is
Visa is the world's largest card network. They don't issue cards, they don't provide merchant accounts, and they don't process your payments. They set the rules, operate the network that connects banks, and fine you when you break their rules.
Understanding what Visa controls vs what your processor controls matters when you're trying to fix problems.

What Visa Actually Does
Visa is NOT:
- Your processor (that's Stripe, Square, etc.)
- Your acquirer (that's your merchant account bank)
- An issuer (that's Chase, Bank of America, Capital One, etc.)
Visa IS:
- The network connecting issuers and acquirers
- The rule-maker for how Visa-branded cards work
- The enforcer when merchants or banks break rules
- The arbitrator in complex disputes
What this means: You never talk to Visa directly. Everything goes through your processor/acquirer.
Visa's Rules That Matter to Merchants
1. Chargeback Monitoring Programs
Visa runs VAMP (Visa Acquirer Monitoring Program) to monitor merchant chargeback ratios:
| Level | Threshold | Consequences |
|---|---|---|
| Processor flagging | ~0.9% ratio (processor-set) | Warnings, remediation requests |
| VAMP Merchant Excessive | 2.2% ratio + 1,500 combined fraud reports + disputes (tightening to 1.5% in April 2026) | $8 per CNP dispute fee (3-month grace for first-time) |
VAMP is an acquirer-level program. Visa monitors your acquirer's portfolio, and your acquirer manages individual merchants. Most processors start watching at ~0.9% (the old VDMP threshold) as their own internal policy.
Timeframe: Rolling 1-month calculation
How it works:
- Your processor reports your ratios to Visa monthly
- If you breach, Visa fines your processor
- Your processor passes fines to you (or terminates you)
- Three consecutive months in a program = mandatory remediation plan
See: Chargeback Monitoring Programs and Zero Point Nine Panic for prevention.
2. Reason Code System
Visa uses a 2-digit reason code format:
| Code Range | Category | Examples |
|---|---|---|
| 10.x | Fraud | 10.4 (CNP fraud), 10.5 (Fraud Monitoring Program) |
| 11.x | Authorization | 11.1 (Card Recovery Bulletin), 11.2 (Declined auth) |
| 12.x | Processing errors | 12.1 (Late presentment), 12.6 (Duplicate) |
| 13.x | Consumer disputes | 13.1 (Not received), 13.2 (Cancelled recurring) |
Full breakdown: Visa Reason Codes
3. Response Timeframes
| Action | Timeframe |
|---|---|
| Representment response | 30 days |
| Pre-arbitration response | 30 days |
| Arbitration filing | 45 days |
Miss these and you auto-lose.
4. Compelling Evidence 3.0
Visa's CE 3.0 program lets you win fraud disputes with historical evidence:
Requirements:
- 2+ prior undisputed transactions on same card
- 120-365 days before disputed transaction
- 2+ matching elements: device ID, IP, shipping address, account
Win rate: 70-85% when CE 3.0 qualifies (vs 15-25% without)
Visa Network Fees (You Pay These)
Visa charges network assessment fees on every transaction:
| Fee Type | Rate | When Charged |
|---|---|---|
| Assessment fee | 0.14% | All Visa transactions |
| Network fee (credit) | 0.13% | Credit cards |
| Network fee (debit) | 0.05% | Debit cards (unregulated) |
| International fee | 1.0% | Cross-border transactions |
| APF (Acquirer Processing Fee) | $0.0195 | Per transaction |
These are non-negotiable. Every merchant pays them (usually hidden in your processor's rate).
Total network fees: ~0.15-0.30% depending on card type and geography.
When Visa Intervenes Directly
Visa steps in when:
1. Excessive Chargebacks
Above ~0.9% (processor threshold):
- Your processor flags you and demands a remediation plan
- Processor may pass through VAMP per-dispute fees ($8 per CNP dispute)
- Continued high ratios lead to processor termination
VAMP Merchant Excessive (2.2%, tightening to 1.5%):
- Visa charges $8 per CNP dispute directly to your acquirer
- Acquirer passes cost to you or terminates
- If no improvement = MATCH listing likely
2. Fraud Clusters
Common Point of Purchase (CPP):
- Multiple fraud complaints trace to your location
- Visa investigates directly
- Forensic examination may be required
- Can lead to MATCH listing (code 02)
3. Rule Violations
Visa fines for:
- Surcharging violations
- Incorrect MCCs
- Late presentment
- Incorrect transaction codes
Fines: $10K-$100K+ per violation
4. Arbitration
If you and the issuer can't resolve a dispute:
- Either party can escalate to Visa arbitration
- Visa makes final decision
- Loser pays arbitration fee ($600+) + the dispute amount
- Visa's decision is binding
When this happens: Rarely. Under 1% of chargebacks reach arbitration.
Visa vs Mastercard: Key Differences
| Factor | Visa | Mastercard |
|---|---|---|
| Market share (US) | ~50% | ~25% |
| Chargeback threshold | ~0.9% (processor) / 2.2% VAMP merchant excessive | 1.5% + 100/month (ECM) |
| Response timeframe | 30 days | 45 days |
| Reason code format | 10.4, 13.1 (2-digit) | 4837, 4853 (4-digit) |
| Monitoring programs | VAMP | ECM/HECM |
| Compelling Evidence | CE 3.0 (strong program) | Similar but less documented |
| Arbitration | Visa decides | Mastercard decides |
For merchants: Processors typically flag Visa disputes earlier (~0.9%) than Mastercard's ECM threshold (1.5%). Visa gives shorter response windows (30 vs 45 days for MC).
Visa's Core Programs
VDMP and VFMP (Legacy - Replaced by VAMP)
VDMP (Visa Dispute Monitoring Program) and VFMP (Visa Fraud Monitoring Program) were replaced by VAMP in April 2025. The old VDMP had a 0.9% + 100 disputes/month threshold that many processors still use as their internal benchmark.
Under VAMP, Visa monitors at the acquirer level and identifies individual "merchant excessive" cases at 2.2% (tightening to 1.5% in April 2026) with 1,500+ disputes. Rather than flat monthly fines, VAMP charges $8 per CNP dispute.
Practical impact: Most processors still flag you around 0.9% because they need to manage their own acquirer-level VAMP ratio (excessive at 0.7%). The 0.9% "danger zone" is real - it's just enforced by your processor, not directly by Visa.
Visa Integrity Risk Program (VIRP)
Monitors rule violations:
- Surcharging violations
- MCC misclassification
- Processing violations
Fines: $10K-$100K per violation
Test to Run
Visa compliance health check:
Week 1: Check your ratios
- Calculate current chargeback ratio (all Visa disputes)
- Calculate fraud ratio (10.x code disputes only)
- Compare to thresholds:
- Under 0.65%: Healthy
- 0.65-0.9%: Warning zone (processor may flag you)
- Over 0.9%: Crisis (processor action likely)
Week 2: Review reason codes 4. Pull last 50 Visa disputes 5. Count by reason code (10.4, 13.1, 13.2, etc.) 6. Identify your top 3 codes
Week 3: Evidence audit 7. For top 3 codes, check if you have required evidence 8. Code 10.4 (fraud): Do you have 3DS? Device matching? 9. Code 13.1 (not received): Do you have tracking + signature? 10. Fix evidence gaps before next dispute
Success criteria: Ratio under 0.65%, evidence collection in place for top 3 codes.
Scale Callouts
Under $100K/month:
- Unlikely to hit high dispute counts at this volume
- Focus on keeping ratio under 0.5%
- VAMP isn't an immediate concern
$100K-$1M/month:
- Can hit both ratio and count thresholds
- Monitor weekly, not monthly
- Set internal alarm at 0.6% ratio
Over $1M/month:
- High risk of VAMP if fraud prevention isn't strong
- Implement chargeback alerts (RDR)
- Consider chargeback guarantee services
Over $10M/month:
- VAMP merchant excessive (2.2%, tightening to 1.5%) becomes the direct threat
- Must have dedicated fraud/chargeback team
- Network relationships matter (through processor)
Where This Breaks
-
Visa rules override your processor: Your processor may say you can do something, but if Visa's rules prohibit it, Visa wins. Always verify network rules for important decisions.
-
Visa doesn't care about your story: You can have a great explanation for why chargebacks spiked. Visa's programs are algorithmic. Over threshold = fines.
-
Visa timelines are strict: 30-day response windows are firm. Weekends and holidays count. Plan for this.
-
Visa won't talk to you directly: All communication goes through your processor/acquirer. If your processor has a bad relationship with Visa, you suffer.
-
Arbitration is expensive and binding: Filing for arbitration costs $600+. If you lose, you pay that plus the dispute amount. Visa's decision is final.
