ISIN Number stands for International Security Identification Number: It is a 12 digit Alpha-Numeric Number. Divided into 3 parts

Read the following from Text Book of NSDL

8.2 International Securities Identification Number
Each security issued bears a unique ISIN issued by the International Standards
Organisation (ISO). In India, the task of issuing ISIN of various securities has been
assigned by SEBI to NSDL. For Government securities, allotment of ISIN is done by
Reserve Bank of India. Each member country has a different code according to the
ISIN Standard (ISO 6166).
ISIN is a twelve-character long identification mark. It has three components – a
pre-fix, a basic number and a check digit.
· The pre-fix is a two digit country code as stated under ISO 3166 (IN for India).
· The basic number is made up of nine alphanumeric digits and/or
· The check digit at the end of the ISIN is computed to check the validity of the
ISIN. It is calculated according to the modulus 10 “Double Add Double Check”.
Distinct ISINs are allotted to securities issued by the same company, issued at
different times or carrying different rights of different terms and conditions. Different
ISINs are issued to physical and dematerialized securities of the same issue.
To understand it in a better manner, let’s take an example:
ISIN INE 475C 01 012 has the following break up:
IN - India
E - Company
475C - Company serial number
01 - Equity (it can be mutual fund units, debt or government securities)
01 - Issue number
2 - Check digit
The third E in the above example). It is as
A - Central government security
B - State government security
