MCC 6012 (API)

In order to reduce fraud, Visa have mandated that domestic financial services providers (Merchant Category Code / MCC 6012) based in Visa Europe Region are required to send additional fields in requests to Trust Payments that denote the recipient of funds. You will need to update the the payload submitted within your JWT to include these fields (only applies to AUTH and ACCOUNTCHECK request types).

  Your Merchant Category Code (MCC) is a four-digit number assigned to you by your acquirer. It is used to classify the business by the type of products or services it provides. If you are unsure of the value of your merchant category code, please contact our Support Team.

  For UK-based merchants with MCC 6012, failure to submit these fields may prevent the transaction from being processed successfully, with a “60025” errorcode being returned in the response.


Once you have processed an AUTH or ACCOUNTCHECK containing these required fields, they can be inherited in future requests, and passed onto the acquiring bank automatically, if required.
