Anatomy of a Credit Union Services Corporation (Australia) Limited Visa Credit Card Number
While credit card number may seem like a random string of digits, they actually contain a large amount of valuable data about the card that can be used for validation and verification purposes.
Digit 1 — The MIIThe first digit of the card is known as the MII digit, and indicates the credit card's scheme. In this case, the MII of 4 indicates that this is a Visa card.
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 443438 indicates that this card was issued by Credit Union Services Corporation (Australia) Limited in Australia.
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.
