Card Issuer


Reason Code



Processing Error


The merchant processed the wrong currency code, or the cardholder wasn’t notified or didn’t agree to the Dynamic Currency conversion.


  • The transaction currency differs from the currency the that the merchant submitted through VisaNet.
  • The merchant applied the DCC after the cardholder declined or didn’t allow the cardholder an opportunity to opt out.


Cardholders and issuers have 120 days to file a dispute related to the claim against the merchant.

Merchants have 20 days to respond to the claim in dispute.

Steps to Prevention

  • Instead of automatically applying DCC to your transactions, afford customers the option to opt in or out.
  • Create systems to manage multiple currencies and train staff on correct procedures for handling the different currencies.
