How Merchant Advice Codes Work

Merchant Advice Codes (MACs) are essential tools for merchants to help prevent fraudulent transactions. But how exactly do they work?

In simplest terms, a MAC is a code that is assigned to each credit card transaction made through a merchant. The code serves as a message that is sent from the merchant’s payment processor to the issuing bank.  Providing additional information about the transaction beyond what is provided by the card itself.

When a transaction is processed, the payment processor sends the MAC along with the card details to the issuing bank. The bank then analyzes the MAC to determine if the transaction is legitimate or suspicious. If the MAC is suspicious, the bank may flag the transaction for review or decline it altogether.

Codes Work

So what type of information does the MAC provide? Some of the most common details include the location of the transaction, the type of card being used, the transaction amount, and the date and time of the transaction. This additional data allows the issuing bank to better assess the transaction and determine if it aligns with the cardholder’s typical spending patterns.

It’s worth noting that not all MACs are created equal. Some codes provide more detailed information than others.  And the level of detail can vary depending on the payment processor and the merchant’s industry. For example, merchants in high-risk industries like online gambling may be required to provide more extensive MAC data to mitigate the risk of fraudulent transactions.

Overall, the effectiveness of MACs depends on a variety of factors.  Including the accuracy and relevance of the data provided and the sophistication of the bank’s fraud detection system. However, as part of a comprehensive fraud prevention strategy.  Implementing MACs can be a valuable tool for reducing the risk of chargebacks and protecting your business’s bottom line.
