Card BIN lookup API

Which network, card type and bank a card's first six digits belong to: Visa, Mastercard, RuPay, debit or credit.

The first six to eight digits of a card (the BIN or IIN) name its network, whether it is debit, credit or prepaid, its product and the bank that issued it. About 374,000 prefixes worldwide, about 12,000 of them Indian, from an open BIN list (CC BY 4.0). Use it to show the right card logo or to route a payment; never send a whole card number.

Network, type and bank of a card prefix

GET/v1/bin/{prefix}

The longest known prefix of the digits given. More than eight digits is refused, so a card number is never looked up. Quality varies: the list is not the networks' own.

What you send here is never written to the log, and the answer is not cached.

Parameter	Description
`prefix`path, required	6 to 8 digits.
