Digits 1-6 — The IIN / BINThe first six digits of the card number, inclusive of the MII, are called the IIN (Issuer Identification Number) or BIN (Bank Identification Number). This sequence uniquely identifies the bank that issued the card. In this case, the IIN of 409851 indicates that this card was issued by Bbva Bancomer in Mexico.
Digits 7-15 — The Account NumberDigits 7-15 of the credit card number contain the Primary Account Number, or PAN, issued by the bank to uniquely identify the account holder. These 8 digits are the most important part of the credit card number.
Digit 16 — The Check DigitThe last digit of the card number (the 16th digit in most cases) is the check digit, which is calculated by applying a mathematical formula called the Luhn algorithm to the preceding portions of the account number. While not actually part of the account number itself, the check digit is essential to allow easy validation of card numbers and detection of typos, missed digits, etc.
