ISO is in contact with different National Standards Organization of the country. Both types of organizations work together on the number of credit cards.

Credit card number
There are mainly 3 components in a credit card number. The first component contains your account information. The second contains information about the card issuing institution. The third component is the checksum.
Number issuer information
This is called issuer information which consists of industry number and issuer identification number. The first number on your credit card is ‘Major Industry Identifier’ or MII. This number shows the identity of the card issuing institution.
After the first number, the next 5 digits are added together, then it is known as the issuer identification number ie IIN. These six numbers indicate the type of card you use. On the basis of this number, merchants take payment. For example, travel and entertainment cards start with the number 3 while banking and financial cards start with the number 5.
The number left after the first 6 numbers of the credit card and leaving one last number in the middle is your account number. There is a unique number for each account holder, which identifies the account holder. The last number of the credit card is called the checker digit or it is also called the checksum. This shows the validity of your card. This number is made under a special algorithm called Luhn formula. Checksum is used to detect the error in payment. Fraud payment is stopped through this number.
