How do I block certain Merchant Category Codes (MCCs)? 

If the card has not been issued yet: 

1. During the card issuance process, set MCC restrictions in the Card Settings section. 

2. Block specific merchant types (e.g., travel, entertainment). 

If the card has already been issued: 

1. Go to the specific card’s page. 

2. Click Card Settings > Edit Settings. 

3. Update the MCC restrictions. 

4. Save changes. 

See the list of MCCs that can be blocked.
