What is ISIN and Why It Matters?

When companies issue shares, debentures, or bonds, each security needs a unique identification number to avoid confusion in trading and compliance. This identifier is called the ISIN (International Securities Identification Number).

In India, every listed and certain unlisted companies must obtain an ISIN for their securities as per SEBI and MCA regulations. Without an ISIN, a company cannot dematerialize its shares or comply with mandatory filings such as PAS-6.

 

What is an ISIN?

The ISIN is a 12-character alphanumeric code that works as a global identifier for securities. It is made up of:

  • Country code (2 letters, e.g., IN for India)
  • Unique security identifier (9 characters)
  • Check digit (1 digit for error detection)
Example:IN0001234567

This makes it easy for regulators, investors, and depositories to track securities across the globe.

 

Why Does ISIN Matter for Companies?

  • Mandatory for Compliance : SEBI and MCA require companies to issue securities only in demat form. For this, an ISIN is compulsory. Unlisted public companies and certain private companies covered under Rule 9B must obtain an ISIN to stay compliant.
  • Dematerialization of Shares : ISIN is essential to convert physical share certificates into electronic form (demat shares). Without it, shareholders cannot hold or trade shares digitally.
  • Transparency and Investor Trust : An ISIN ensures clarity and eliminates duplication. It acts like a passport for securities, increasing transparency for investors and regulators.
  • Ease of Trading and Reporting : ISINs are used in all transactions, filings, and compliance reports, including PAS-6 reconciliation statements, e-voting, and buybacks.

 

Role of an RTA in ISIN Generation

To obtain an ISIN, companies must apply through a Registrar & Transfer Agent (RTA). The RTA coordinates with depositories like NSDL and CDSL to issue the ISIN after verifying documents such as:

  • Certificate of incorporation
  • Board resolution
  • Share capital details
  • KYC of directors and authorized signatories

At Nextgen RTA, we simplify this process by handling documentation, liaising with depositories, and ensuring smooth issuance of ISIN.
