Specific merchant types have been created within CardValet, and these merchant types can be used for controls or alerts via the Alert Preferences or Control Preferences screen. Each of the merchant types contains various merchant category codes (MCC). Note: It is possible for a retailer to forward a MCC that may differ from the CardValet merchant type classification. Merchant types currently supported are: Department Store, Entertainment, Gas Station, Grocery, Household, Personal Care, Restaurant, Travel, and Others.
