Visa and Mastercard collectively process over 80% of card transactions worldwide, but their dispute resolution systems differ in important ways. Merchants who treat all chargebacks the same—regardless of which network issued the card—are leaving win rate and money on the table. The reason codes are different, the timelines are different, the evidence requirements are different, and the monitoring programs carry different thresholds and penalties.
This guide provides a comprehensive comparison so you can tailor your dispute response and prevention strategies by network.
Reason Code Systems
Visa and Mastercard use completely different reason code numbering systems and organize dispute categories differently.
| Dispute Category | Visa Reason Codes | Mastercard Reason Codes |
|---|---|---|
| Fraud | 10.1, 10.2, 10.3, 10.4, 10.5 | 4837, 4863, 4871 |
| Authorization | 11.1, 11.2, 11.3 | 4808, 4812, 4834 |
| Processing Errors | 12.1, 12.2, 12.3, 12.4, 12.5, 12.6, 12.7 | 4834, 4831, 4842 |
| Consumer Disputes | 13.1, 13.2, 13.3, 13.4, 13.5, 13.6, 13.7 | 4853, 4855, 4841 |
Visa uses a hierarchical system (category.subcategory) with 26 active reason codes across 4 categories. Mastercard uses 4-digit codes with fewer total codes but broader categories. The practical impact: Visa's system is more granular, which means your evidence requirements are more specific. Mastercard's broader codes sometimes give you more flexibility in how you structure your response.
Common Equivalent Codes
| Dispute Scenario | Visa Code | Mastercard Code |
|---|---|---|
| Item not received | 13.1 | 4855 |
| Not as described / defective | 13.3 | 4853 |
| Fraud — card not present | 10.4 | 4863 |
| Cancelled recurring | 13.2 | 4841 |
| Credit not processed | 13.6 | 4853 (sub-category) |
| Duplicate processing | 12.6 | 4834 |
Time Limit Differences
One of the most impactful differences between the two networks is the response timeline. For a detailed breakdown including Amex and Discover, see our complete time limits guide.
| Stage | Visa | Mastercard |
|---|---|---|
| Cardholder filing window | 120 calendar days | 120 calendar days |
| Merchant response (representment) | 30 calendar days | 45 calendar days |
| Pre-arbitration / second chargeback response | 30 calendar days | 45 calendar days |
| Arbitration filing | 10 business days | 45 calendar days |
Mastercard's 45-day response window gives you 50% more time than Visa's 30 days. Use that extra time for Mastercard disputes that require gathering evidence from third parties (carriers, OTAs, etc.). For Visa disputes, prioritize speed—start gathering evidence the day you receive notification.
Evidence Requirements
Both networks define "compelling evidence" standards, but their specific requirements differ.
Visa Compelling Evidence
Visa has the more structured evidence framework, particularly with the introduction of Compelling Evidence 3.0 (CE 3.0). For fraud disputes (10.4), CE 3.0 allows merchants to submit evidence from two prior undisputed transactions that share at least two matching data points with the disputed transaction:
- IP address matching the disputed transaction
- Device ID or fingerprint matching
- Shipping address matching the delivery address on the disputed transaction
If the merchant can demonstrate these matches, Visa considers it compelling evidence that the cardholder made the purchase. This is a significant advantage for merchants with repeat customers.
Mastercard Evidence Standards
Mastercard's evidence requirements are defined by reason code but are generally less prescriptive than Visa's. Mastercard places heavy emphasis on:
- Proof of delivery with tracking for item-not-received disputes
- Authorization records (AVS, CVV) for fraud disputes
- Terms and conditions acceptance for cancellation disputes
- Customer communication records across all categories
Mastercard doesn't have a direct equivalent to Visa's CE 3.0 program, which means fraud dispute responses for Mastercard rely more on traditional authorization evidence and delivery confirmation. See our evidence guide for detailed requirements by reason code.
Monitoring Programs: VDMP vs. ECP
Both networks operate merchant monitoring programs, but the thresholds, structures, and penalties differ significantly. For a deeper dive into ratio calculations, see our chargeback ratio guide.
| Feature | Visa VDMP/VFMP | Mastercard ECP |
|---|---|---|
| Early warning threshold | 0.65% + 75 disputes | No formal early warning tier |
| Standard monitoring threshold | 0.9% + 100 disputes | 1.5% + 100 chargebacks |
| Excessive threshold | 1.8% + 1,000 disputes | 3.0% + 300 chargebacks |
| Ratio calculation method | Chargebacks filed in month / transactions in same month | Chargebacks for month's transactions / transactions in that month |
| Remediation period | 4 months before fines begin | Fines can begin sooner; varies by acquirer |
| Monthly fines (standard) | $50 per chargeback after month 4 | $25,000+ per month |
| Monthly fines (excessive) | $50,000+ per month | $50,000-$100,000+ per month |
| Blacklist | MATCH list (5-year listing) | MATCH list (shared with Visa) |
Visa's VDMP triggers at 0.9%—significantly lower than Mastercard's ECP at 1.5%. This means you can be in compliance with Mastercard while already in a Visa monitoring program. Always optimize for the stricter standard (Visa's) to stay safe across both networks.
Pre-Arbitration vs. Collaboration
After a merchant's representment is rejected by the issuer, each network has a different second-stage process.
Visa Pre-Arbitration
Visa's pre-arbitration stage allows the issuer to file a second chargeback if they disagree with the representment outcome. The merchant then has 30 days to either accept the chargeback or escalate to arbitration. This is essentially a final negotiation step before binding arbitration.
Mastercard Collaboration
Mastercard uses a "collaboration" process where the acquirer and issuer communicate through Mastercard's system to resolve the dispute. If collaboration fails, either party can escalate to arbitration within 45 days. Mastercard's collaboration process is generally considered more flexible than Visa's pre-arbitration, allowing for more back-and-forth between parties.
Arbitration Costs
| Cost Element | Visa | Mastercard |
|---|---|---|
| Filing fee | $500 | $300-$500 |
| Who pays | Losing party | Losing party |
| Review fee | Up to $500 additional | Up to $400 additional |
| Decision timeline | Typically 30-60 days | Typically 30-90 days |
| Binding? | Yes | Yes |
Arbitration should be reserved for high-value disputes where you have very strong evidence. The filing fee, combined with the risk of paying the loser's fee if you lose, means arbitration is rarely worthwhile for disputes under $500-1,000.
Prevention Programs
Both networks offer merchant-facing tools designed to prevent chargebacks before they're filed.
| Feature | Visa Order Insight (Verifi) | Ethoca (Mastercard) |
|---|---|---|
| How it works | Provides transaction details to issuers so they can resolve inquiries before filing a chargeback | Sends real-time alerts when a cardholder initiates a dispute, giving the merchant a window to refund |
| Merchant action | Transaction data is shared automatically; merchant can also receive alerts and choose to refund | Merchant receives alert and has a window (typically 24-72 hours) to issue a refund |
| Impact on ratio | Resolved inquiries don't become chargebacks, so ratio is unaffected | Refunds issued via Ethoca alerts prevent the chargeback from counting against your ratio |
| Cost | Per-inquiry fee (varies by provider) | Per-alert fee (typically $15-40 per alert) |
| Cross-network coverage | Primarily Visa, with some cross-network coverage through Verifi | Primarily Mastercard, with growing Visa coverage |
Enroll in both Visa Order Insight and Ethoca to maximize your prevention coverage across both networks. The per-alert fees are almost always less than the cost of a chargeback ($25-100 in fees alone, plus the transaction amount, plus the ratio impact).
Liability Shift Rules
Both networks provide a liability shift for authenticated transactions (3D Secure), but the mechanics differ slightly.
| Scenario | Visa | Mastercard |
|---|---|---|
| 3DS authenticated — fraud chargeback | Liability shifts to issuer (merchant protected) | Liability shifts to issuer (merchant protected) |
| 3DS attempted but not completed | Liability may still shift if merchant attempted 3DS and issuer didn't participate | Similar; liability shift may apply for attempted authentication |
| Non-fraud disputes (13.x / 48xx) | No liability shift (3DS only covers fraud) | No liability shift (3DS only covers fraud) |
Important: 3D Secure liability shift only applies to fraud-related chargebacks. If a customer files a "not as described" or "item not received" dispute, 3DS authentication does not protect the merchant—regardless of the network.
Practical Implications for Merchants
Knowing the differences is only valuable if you act on them. Here are the practical takeaways:
- Track ratios separately: Calculate and monitor your Visa and Mastercard chargeback ratios independently using each network's methodology.
- Optimize for Visa's stricter thresholds: Visa's 0.9% threshold is nearly half of Mastercard's 1.5%. Building your prevention strategy around Visa's standard keeps you compliant with both.
- Prioritize Visa disputes by speed: With only 30 days to respond (vs. Mastercard's 45), Visa disputes need to be actioned immediately upon receipt.
- Leverage CE 3.0 for Visa fraud disputes: If you have repeat customers, Visa's Compelling Evidence 3.0 is a powerful tool that has no Mastercard equivalent.
- Customize response templates by network: The reason codes are different, so your rebuttal letters should reference the correct codes and requirements for each network.
- Enroll in both prevention programs: Visa Order Insight and Ethoca together provide the broadest prevention coverage.

Which network is easier to win chargebacks against?
Neither network is inherently "easier." Win rates depend on your evidence quality and how well your response matches the specific reason code requirements. That said, Mastercard's longer response windows (45 days vs. 30) give you more time to build a strong case. And Visa's CE 3.0 program provides a powerful evidence framework for fraud disputes that Mastercard lacks. Overall, merchants with strong documentation tend to see similar win rates across both networks.
Do I need different response templates for Visa and Mastercard?
Yes. At minimum, your rebuttal letters should reference the correct reason code for the network (Visa 13.1 vs. Mastercard 4855), address the network-specific evidence requirements, and be submitted within the correct timeframe. Using a Visa reason code in a Mastercard dispute response signals to the reviewer that you're using a generic template, which can undermine your credibility.
Can a chargeback count against both my Visa and Mastercard ratios?
No. A chargeback is filed on one specific card, which belongs to one specific network. A Visa card chargeback only affects your Visa ratio, and a Mastercard chargeback only affects your Mastercard ratio. However, the same underlying merchant behavior (poor billing descriptors, slow refunds) can drive chargebacks on both networks simultaneously.
Is Visa Compelling Evidence 3.0 worth implementing?
If you have any meaningful volume of repeat customers, absolutely. CE 3.0 provides a powerful, data-driven defense against fraud chargebacks (10.4) by demonstrating that the same cardholder made previous undisputed transactions. The implementation requires logging and matching IP addresses, device IDs, and shipping addresses across transactions, but the payoff in improved fraud dispute win rates is substantial.
