ISIN Data from various public securities. You can sort and filter this dataset in your browser at https://flatgithub.com/captn3m0/india-isin-data.

Automatically updated every midnight (IST).

Note: The NSDL Website returns zero valid results for INA, INB, so those are not tracked.

ISIN Structure

ISIN (International Securities Identification Number) is defined by ISO 6166:2021 and adopted in India by BIS as IS 15415:2021 ((PDF)) ((PDF2)). ISINs in India are allotted by NSDL for all securities except Government Securities (See Page 9).

This Indian Standard (Second Revision) which is identical with ISO 6166 : 2021 ‘Financial services - International securities identification number (ISIN)’ issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on recommendation of the Banking and Financial Services Sectional Committee and approval of the Services Sector Division Council.

ISIN, as per the ISO standard consists of 3 parts:

  1. A 2 Character country code as prefix (ISO-3166). For ISINs issued in India, this will always be IN.
  2. A Basic Identification Number. 9 alphanumeric characters left padded with zeroes.
  3. A check digit.

The basic number in India is issued by NSDL and is composed of 4 parts:

  1. A 1-character Issuer-Type. This varies from A-F/9.
  2. A 4-character Issuer code. Alphanumeric.
  3. A 2-character Security Type. Alphanumeric.
  4. A 2-digit serial number for the security itself. Alphanumeric.

Hence, each issuer can issue 36^2 = 1296 securities under each type.
The table below explains the same with an example:

Field Country Code Issuer Type Issuer Code Security Type Serial Number Check Digit
Index 1 2 3 4 5 6 7 8 9 10 11 12
Class I N A-F,0-9 alpha alpha alpha alpha alpha alpha alpha alpha 0-9
Sample I N F 7 8 9 F 0 1 X A 0

Here's the breakdown of the above ISIN (INF789F01XA0):

  • Country Code: IN
  • Issuer Type: F (Mutual Funds)
  • Issuer Code: 789F (UTI Mutual Fund)
  • Security Type: 01 (Equity Shares)
  • Serial Number: XA
  • Check Digit: 0

Issuer Code

Please see issuers.csv (🚧)

Security Type

The security type is defined in the 8th and 9th character of the ISIN code. The same security type code can have different meanings against different issuers.

This table is based on analysis done on real data. A lot of categories (such as Bonds) are fluid, and the exact description in the dataset might not match the security type in this table (As an example the dataset might state "Deep Discount Bond" instead of "Bond". Note that some other sources on the Internet might differ with this table. If you find a ISIN that does not fit in the following table correctly, please create an issue with the ISIN.

Check Digit

The last digit (check-digit) is calculated using the Luhn Algorithm with a slight change to accommodate alphanumeric characters. Alphabets are converted to digits by adding 9 to the usual numeric value of each letter. For example A=10, B=12, C=13, ..., Z=35. A few examples:
