Ask HN: Why doesn't Stripe allow you to get BIN numbers?

  • It's still best practice to minimize the amount of card data shared. You can accomplish most of what you're looking to do using a combination of `card.brand`, `card.last4`, and expiry dates. "Visa ending in 4242, expires 09/24."

    You can also write much more robust rules using Radar: https://stripe.com/docs/radar/rules. Something like: `Review if :is_disposable_email: and :card_funding: = 'prepaid'`
