What is ISIN?

ISIN stands for International Securities Identification Number. It is a 12-character alphanumeric code that internationally identifies financial instruments. It is allocated by the National Numbering Agency (NNA) of the respective country.

In India, the agency responsible for allocating ISIN to financial securities is National Securities Depository Limited (NSDL). Since more than 200 countries follow this numbering system, you can identify securities traded on 100+ exchanges using ISIN.

Let’s Decode the Format of ISIN

Here’s an ISIN of a hypothetical company, ABC Limited, headquartered in India:

IN E123456XY 7

There are 3 elements to this 12-digit ISIN code:

  1. The first 2 alphabets (IN) represent the country code where the company has its headquarters. For India, it is IN. US companies have codes starting with the US, whereas companies headquartered in Japan have ISIN starting with JP.
  2. The next 9 characters (E123456XY) are reserved for the unique identification number provided by the numbering agency (NSDL in the case of Indian companies).
  3. The last digit, aka check digit, is used to reduce the occurrences of errors and fraud. 

Where to find the ISIN of Stocks?

Now that you know what is ISIN and its format, let’s understand how you can find out the unique code of each stock.

There are three ways you can search for the ISIN of a particular stock - via NSDL, NSE, or BSE’s website. Here’s how you can do it.
