Mastercard Account Validation

The Mastercard Account Validation API service enables Mastercard customers to check that the supplied name(s) and, optionally, Card Verification Code (CVC or CVV) for an account match the account records held by the card issuer. Mastercard routes validation requests to Mastercard or Visa issuers, depending on the account type. The API response will provide status values indicating the matching results from the issuer.
