The MCC (Merchant Category Codes) are four-digit numbers used to categorise the transactions and to classify merchants and business by the type of good or services provided.
The Tuum system allows setting up two types of MCC groups:
Whitelist - only the authorisations with the MCC groups that are defined in whitelist are allowed, other authorisations will be declined.
Blacklist - all authorisation requests with the MCC groups that are defined in blacklist will be declined.
When setting up a card product you can define one or many Allowed mcc groups and set one default mcc group.
Once the allowed and default mcc groups are selected, click the Create mcc group button and fill in the following parameters, click Submit:
Mcc group name - Enter a group name. It can only consist of the upper-case letters, numbers and underscores. It must start with a letter and cannot end with an underscore.
Control Type - Select if the group is whitelisted or blacklisted.
Mcc codes - Select the relevant mcc codes. You can select multiple values.
Organisation unit - Select the organisation unit from the list.
MCC settings are optional. If not required, you can skip this section and continue with the .
