What is BIN 388734?

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.

Merchants, fraud teams, ad platforms and developers use BIN data to route transactions, localize checkout, detect chargebacks and decide which card products they accept. BIN 388734 itself is public metadata — it identifies the issuer, not the cardholder.
