Spoiler alert: the network rarely decides if a card works for ads.
What actually matters is BIN country, currency, 3DS behavior, and spend controls — configured together.
A US Visa and a US Mastercard from the same issuer usually perform almost identically. The real difference is in the ad setup.
So the question "which network is better for ad spend" is actually irrelevant. A better one is: does the BIN match my billing setup? Is the currency right? Are the limits aligned?
CardsPro gives you 20+ BINs across various GEOs, both networks included — so you can configure by scenario, not by superstition.
