ISIN Application explained: this guide covers what it means, who it applies to, the step-by-step process, documents required, fees, due dates and penalties in India — so you can stay compliant with confidence and avoid costly mistakes.
An ISIN application by a private company needs certified constitutional documents, a board resolution naming authorised signatories, the audited annual report, a net worth certificate, an R&T Agent confirmation, a company undertaking and three franked copies of the tripartite agreement — and the articles may need amending first.
What an ISIN is
An ISIN — International Securities Identification Number — is a unique twelve-digit alphanumeric code assigned to securities such as shares, debentures and bonds upon admission to the depository system. The first two digits signify the country of registration; for Indian securities they are "IN".
Different securities issued by the same issuer carry distinct ISIN codes, which is why Rule 9A(4) speaks of securing an ISIN for each type of security. A company with equity shares, preference shares and debentures makes an ISIN application covering each of them separately, not one for the company.
Which securities the ISIN application must cover
The handbook is asked directly whether Rule 9B is confined to shares. Its answer is that the MCA notification of 27 October 2023 uses the word "securities", so the requirement applies to all the securities of private companies — equity shares, preference shares, debentures and the like.
"Securities" takes its meaning from section 2(81) of the Companies Act, 2013, which adopts section 2(h) of the Securities Contracts (Regulation) Act, 1956. That is an inclusive definition covering shares, scrips, stocks, bonds, debentures and debenture stock, derivatives, units of collective investment schemes and mutual funds, security receipts, government securities, and rights or interest in securities.
A private company that has issued compulsorily convertible preference shares to an investor, or debentures to a promoter or a lender, needs an ISIN application for those instruments too — not only for its equity.
This matters for planning, because each instrument type is a separate line in the ISIN application, is separately reported in Form PAS-6, and must be separately dematerialised by its holder before any transfer. A company that obtains an equity ISIN and stops there has not complied with Rule 9B, however clean its share register looks.
The documents
The list the handbook gives as generally required for an ISIN application is:
- Certified true copies of the memorandum and articles of association along with the certificate of incorporation;
- a certified true copy of the board resolution naming the signatories authorised by the Board to execute documents, with the list of authorised signatories and specimen signatures;
- a certified true copy of the audited annual report for the last financial year;
- a net worth certificate as per that audited annual report, in the prescribed format;
- a confirmation letter from the Registrar & Transfer Agent, in the prescribed format;
- an undertaking from the company, in the prescribed format;
- the tripartite agreement between the issuer, the R&T Agent and NSDL or CDSL — three copies with franking; and
- other depository-specific documents as may be required.
The two corporate actions to take first
| Action | Position |
|---|---|
| Board resolution | Required. A private company must pass a board resolution for facilitating dematerialisation of its securities and submit it to the depository while applying for the ISIN |
| Amendment of articles | Conditional. The depository may check whether the articles contain a provision relating to dematerialisation. If they do not, the company shall amend the articles to include it |
Of the two, the articles amendment is the one that sets the calendar, and it is routinely discovered too late.
A board resolution can be passed at short notice. Amending the articles cannot: it needs a special resolution in general meeting, with notice, and then a filing with the Registrar. A private company that discovers at the depository's document-check stage that its articles are silent on dematerialisation has added weeks to its timeline.
Note the handbook's careful wording — the depository "may check". Whether the point is raised is a matter of depository practice rather than a statutory precondition. The safe course is to review the articles at the outset and, where they are silent, amend before the ISIN application goes in.
The NSDL and CDSL choice
The handbook flags a trap that is invisible until a shareholder tries to dematerialise. If the company has applied for its ISIN through NSDL and a shareholder holds a demat account with CDSL, that shareholder will not be able to dematerialise the shares.
Its advice follows directly: when making the ISIN application, the company should take into account the depository with which its current shareholders have established their demat accounts in most cases.
This is the single most consequential decision in the whole ISIN application, and it is made before any shareholder is involved. Reversing it later means the company applying afresh through the other depository.
The practical step is simple and is worth building into the engagement: ask the shareholders where they already hold demat accounts before the depository is chosen. In a private company with a handful of shareholders this is a short exercise, and it avoids the position where the company has an ISIN that most of its own members cannot use.
The Registrar & Transfer Agent
A company that wishes to offer a demat facility to its shareholders may avail the services of an R&T Agent by entering into a tripartite agreement with the R&T Agent, the depository and the company. The R&T Agent's confirmation letter is part of the ISIN application document set, and three franked copies of the tripartite agreement accompany it.
The details of SEBI-recognised registrars to an issue and share transfer agents are published on the SEBI website in its list of recognised intermediaries.
Practical checklist
- Review the articles for a dematerialisation provision at the very start.
- Survey where existing shareholders hold demat accounts before choosing NSDL or CDSL.
- Pass the board resolution naming authorised signatories, with specimen signatures.
- Make a separate ISIN application entry for each type of security — equity, preference, debentures.
- Obtain the net worth certificate from the latest audited annual report, in the prescribed format.
- Appoint an R&T Agent and execute the tripartite agreement in three franked copies.
- Ask the depository for its own additional document list early.
- Keep certified copies of the memorandum, articles and certificate of incorporation ready.
Common mistakes
- Taking one ISIN for the company rather than one per type of security.
- Discovering the articles are silent at the document-check stage.
- Choosing the depository on price without checking where the shareholders bank their securities.
- Forgetting preference shares and debentures in the ISIN application.
- Sending unfranked tripartite agreement copies.
- Treating the board resolution as internal and not submitting it with the application.

What documents are needed for an ISIN application?
Certified true copies of the memorandum and articles with the certificate of incorporation; a certified board resolution naming authorised signatories with specimen signatures; the certified audited annual report for the last financial year; a net worth certificate as per that report; a confirmation letter from the R&T Agent; an undertaking from the company; three franked copies of the tripartite agreement; and other depository-specific documents.
Is a board resolution required?
Yes. A private company must pass a board resolution for facilitating dematerialisation of its securities and submit it to the depository while applying for the ISIN.
Over 90% of compliance penalties in India arise from missed due dates — timely handling can save businesses thousands of rupees each year.
