Payment Response Analysis

Merchant Advice Code

The parameter merchant_advice_code provides additional information on a given transaction response decline. Merchant Advice Codes are supported by Mastercard to enable issuers to communicate insights to acquirers and merchants and thus let them optimize their subsequent retry strategies for declined transactions.

01 New account information available
02 Cannot approve at this time, try again later
03 Do not try again
04 Token requirements not fulfilled for this token type
21 Payment Cancellation

Merchant advice code values 03 and 21 are intended to send a clear message that a transaction should not be resubmitted for approval:

  • Value 03 is sent by issuers to indicate that an account is closed or fraudulent, and that no further approvals will be forthcoming;
  • Value 21 is sent by Mastercard Payment Cancellation Service (PCS) to indicate a cardholder canceled the agreement and instruct the merchant and acquirer to not retry the transaction.

In order to avoid unnecessary declines, pay close attention to the returned merchant advice code value.
