Does anyone have access by PDF or a direct link to the merchant codes for Visa, Mastercard, and AMEX?

After beginning to read the fine print (the credit card disclosures) for what the items actually fall under what category, it has caught my attention.

For instance, after doing some digging on AMEX, they don’t consider most Walmarts and Targets as supermarkets, so if you thought you were receiving 3X points for groceries (if you have a card with them that offers this perk), you may not be getting such points each time.

Please don’t shoot the messenger as I’m trying to see what falls under what for no surprises at the end of the day. This might be helpful to those who are curious too.

Thank you in advance!
