Merchant advice codes
Navigating merchant advice codes for improved transaction outcomes and business insight

Merchant Advice Codes (MACs) are introduced by Mastercard to clearly communicate to merchants the reason for declining transactions, and the course of action that merchants can take. These codes provide insights into why a payment failed and recommendations on whether and when it can be retried.

Mastercard set the MAC values and may expand this list as part of their ongoing efforts to enhance payment system efficiency.

Please note that the availability of the MAC code depends on the policies of both the card issuer and the acquirer. It is important to understand that this functionality is not yet universally supported by all banks.

Solidgate ensures our system stays current by quickly integrating new codes from our providers, including any updates from Mastercard.

These codes are available to our merchants, potentially without prior notice, to guarantee prompt implementation.
