  • The next few digits are the Issuer Identification Number (IIN) or the Bank Identification Number (BIN), followed by the account number. yes, your credit card has an account number attached to it and that you can find out in case you have created online banking access for your credit card also.
  • The last digit or the last 2 digits make up check digit(s) used as a security/verification number. The number of digits used to indicate the bank account and check numbers vary depending on the Credit Card company.
