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. For BIN 555479, that institution is Commercial Bank Of Qatar Q.S.C in Qatar. The card runs on the Mastercard network. Transactions settle in QAR.

Mastercard is a global network whose BINs fall in the 51–55 and 2221–2720 ranges, accepted at merchants worldwide.
