    Have you considerd this bank identification code on check yet? This checker allows you to identify the issuing bank by the card number. To begin, enter the first six digits of your bank card number (BIN) and press “Search”.

    Most often 16 digits sometimes 17. First numbers correlate to your card, mastercard, amex, visa etc.

    The CVC on the back are three numbers. On American Express (AMEX) cards, it is usually a four digit code on the front. They’re your security numbers. SUPER RANDOM!
