Check bank, country, card type, and issuer information for BIN 300377.

What is BIN 300377?

BIN 300377 is on the Diners Club network.

A Bank Identification Number (BIN, or Issuer Identification Number / IIN) is the first 6 to 8 digits of any payment card. It tells the payment network which institution issued the card, what kind of card it is, and where it was issued. The card runs on the Diners Club network.

Diners Club International is one of the oldest card networks; its cards are processed over the Discover network in many regions.

In practice this prefix is what a checkout sees first — risk engines score it, gateways route on it, and merchants use it to decide whether to accept the card class at all. BIN 300377 is institutional data under the ISO/IEC 7812 standard — looking it up reveals the issuing program, nothing about any cardholder.
