Visa

TL;DR
  • 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:

LevelThresholdConsequences
Processor flagging~0.9% ratio (processor-set)Warnings, remediation requests
VAMP Merchant Excessive2.2% 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:

  1. Your processor reports your ratios to Visa monthly
  2. If you breach, Visa fines your processor
  3. Your processor passes fines to you (or terminates you)
  4. 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 RangeCategoryExamples
10.xFraud10.4 (CNP fraud), 10.5 (Fraud Monitoring Program)
11.xAuthorization11.1 (Card Recovery Bulletin), 11.2 (Declined auth)
12.xProcessing errors12.1 (Late presentment), 12.6 (Duplicate)
13.xConsumer disputes13.1 (Not received), 13.2 (Cancelled recurring)

Full breakdown: Visa Reason Codes

3. Response Timeframes

ActionTimeframe
Representment response30 days
Pre-arbitration response30 days
Arbitration filing45 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)

See: Compelling Evidence 3.0


Visa Network Fees (You Pay These)

Visa charges network assessment fees on every transaction:

Fee TypeRateWhen Charged
Assessment fee0.14%All Visa transactions
Network fee (credit)0.13%Credit cards
Network fee (debit)0.05%Debit cards (unregulated)
International fee1.0%Cross-border transactions
APF (Acquirer Processing Fee)$0.0195Per 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

FactorVisaMastercard
Market share (US)~50%~25%
Chargeback threshold~0.9% (processor) / 2.2% VAMP merchant excessive1.5% + 100/month (ECM)
Response timeframe30 days45 days

Monitoring programsVAMPECM/HECM
Compelling EvidenceCE 3.0 (strong program)Similar but less documented
ArbitrationVisa decidesMastercard 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

  1. Calculate current chargeback ratio (all Visa disputes)
  2. Calculate fraud ratio (10.x code disputes only)
  3. 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

  1. 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.

  2. 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.

  3. Visa timelines are strict: 30-day response windows are firm. Weekends and holidays count. Plan for this.

  4. 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.

  5. 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.
