Credit Card Number

A credit card number is a sequence of numbers that is typically printed on the front or back of a credit card. The number is required for the cardholder to be able to make purchases with the credit card. A credit card number typically consists of 16 digits. The first few digits of a credit card number are known as the issuer identification number (IIN), which identify the issuer of the card. The IIN is followed by a variable number of digits that are used to identify the individual account number. The last digit of a credit card number is known as the check digit, and is used to verify that the credit card number is valid.
