  • Visa

    Visa recently introduced the Visa Claims Resolution (VCR) initiative, a new streamlined dispute process. Mastercard is expected to announce similar changes in 2019. This page is your one-stop resource for information regarding the new dispute and chargeback processes.

    Visa Claims Resolution (VCR) Overview

    Visa Claims Resolution (VCR) is Visa’s new dispute (chargeback) program. The primary objective of VCR is to streamline the dispute process while migrating from a litigation-based dispute model to a liability assignment model. In addition, the process will proactively eliminate invalid disputes by leveraging existing data where possible. VCR will provide enhanced dispute rules that reduce timeframes and offer a faster end-to-end cycle time for resolution.

    Effective April 14, 2018 every merchant, acquirer and issuer worldwide that processes through the Visa network will be required to implement the new VCR program rules.

    What’s changing with VCR?

    • Visa has consolidated the 22 legacy reason codes into four dispute categories:
      • 10 – Fraud
      • 11 - Authorization
      • 12 - Processing Errors
      • 13 - Consumer Disputes
    • The four dispute categories are grouped into two distinct processes:
      • Allocation (10 and 11)
      • Collaboration (12 and 13)
    • Visa has shortened the end-to-end cycle for dispute resolution to 30 days.
    • No provisional credit will be given for the Allocation dispute process when a dispute is challenged.
    • Invalid disputes will be blocked when processed through the new set of business rules.
    • Chargeback processes and systems will be updated to reflect the new reason codes and case statuses effective April 14, 2018.

  • Mastercard


    Mastercard Claims Manager (Effective May 9, 2019)

    Mastercard announced that the arbitration chargeback and mandated pre-arbitration process changes for dual message disputes will move from April 12, 2019 to April 17, 2020. The schedule for the remaining previously announced changes involving reason code consolidation and API interaction with Mastercard have not changed. The scope adjustment should allow us to process chargebacks on the enhanced system, and address any code and process issues before removing the arbitration chargeback.

    Why is Mastercard changing the Dispute Resolution process?

    • Significant increase in improper/invalid chargebacks and representments
    • Increase in chargebacks under $25 (+15%)
    • Significant increase in non-fraud disputes
    • Chargeback timeframes and processes haven’t changed in more than 20 years
    • To reduce the number of improper compliance cases

    What is changing with the Mastercard Dispute Resolution Initiative?

    • Real-time dispute processing between Worldpay and Mastercard
      • Enables self-service for merchants
    • Updating DM Activity File to include Mastercard dispute data
      • File layout updates to reflect MCM
    • Rules and process changes
      • In 2020, pre-arbitrations will replace second chargebacks
        • Issuers will send pre-arbs and file arbitration instead of merchant
      • Mastercard is encouraging all parties to switch to consolidated reason codes

    What is not changing with the Mastercard Dispute Resolution Initiative?

    • Timeframes for merchants to respond
      • 45 days to represent a chargeback
        • 30 days to respond to a retrieval request
      • Dispute process
        • Until 2020, it will remain chargeback/representment/second chargeback/pre-arb/arb.
