Issuer Identification Number (IIN) / Bank Identification Number (BIN)
The first six numbers on all credit cards are referred to as the issuer identification number (IIN) or bank identification number (BIN). You can use the first six digits of your credit or debit card to search for the card’s network, issuing bank, and the location where the card was issued.
Discover issues all its cards through Discover Bank, unlike other card networks. So, no matter what the first six numbers are, if it starts with 6 Discover Bank issued the card.
