The following attributes may be targeted:

  • MCC: A four-digit number listed in ISO 18245. An MCC is used to classify a business by the types of goods or services it provides.
  • COUNTRY: Country of entity of card acceptor. Possible values are: (1) all ISO 3166-1 alpha-3 country codes, (2) QZZ for Kosovo, and (3) ANT for Netherlands Antilles.

  • MERCHANT_ID: Unique alphanumeric identifier for the payment card acceptor (merchant).
  • DESCRIPTOR: Short description of card acceptor.

  • RISK_SCORE: Network-provided score assessing risk level associated with a given authentication. Scores are on a range of 0-999, with 0 representing the lowest risk and 999 representing the highest risk. For Visa transactions, where the raw score has a range of 0-99, Lithic will normalize the score by multiplying the raw score by 10x.
