Understanding MCC Codes

Every time you use your credit card, the merchant is assigned a four-digit Merchant Category Code (MCC). This code tells the credit card network what type of business you're shopping at—and it directly affects how many rewards points, miles, or cashback you earn.

For Singapore credit card users, understanding MCC codes is the secret to maximizing rewards. By knowing which MCC codes earn bonus rates on your cards, you can ensure you're always using the optimal card for every purchase.


How MCC Codes Work

When a merchant sets up to accept credit cards, they are classified into an industry category and assigned a corresponding MCC code. This code is sent along with every transaction processed through their terminal.

Common MCC Code Examples

Grocery Stores5411
Restaurants5812
Online Shopping5399
Airlines3000-3299
Hotels3501-3599
Gas Stations5541

Credit card issuers use these MCC codes to determine bonus categories. For example, a card may offer 4 MPD on dining (MCC 5812, 5814) but only 1 MPD on other purchases. Some cards use whitelists (only specific MCCs earn bonuses) while others use blacklists (all MCCs earn bonuses except excluded ones).


Why MCC Codes Matter for Singapore Cardholders

In Singapore's competitive credit card market, many cards offer bonus rewards on specific MCC categories. Understanding these patterns can help you earn significantly more rewards on the same spending.

Pro Tip: Check Before You Spend
