Numbered shares: what they are, requirements, and more

Learn what Numbered shares are, why they are required and some countries, and how to automate them with Capboard

What are numbered shares?

In some countries, each company share needs to be identified with a unique number to distinguish them. Share numbers are assigned when shares are issued, and noted when transferred.

Numbered shares were widely used in the past to certify who was the true owner of a share. Some countries used share certificates, others numbered shares or made mandatory for companies to keep record of their shareholders in public records. Today, they are still required in some jurisdictions, and tools like Capboard help company directors and lawyers managing share numbers.

Example of numbered shares

If a company has 3,000 outstanding shares, there will be a share numbered as 1, another one as 2... until the 3,000th. If the company has 3 shareholders owning 33% of the company each (1,000 shares), share numbers will be as follow:

  • Shareholder 1: 1 - 1,000
  • Shareholder 2: 1,001 - 2000
  • Shareholder 3: 2,001 - 3,000

Share number requirements

Numbering shares follow the same structure, wherever it is used:

  • Share numbers are unique.
  • Numbers are assigned by order when new shares are issue. So it a company already has 10,000 shares and issues 1,000 more, its numeration will be 10,001-11,000.
  • When shares are transferred to another shareholder, the numbers are kept.

    2. all the issued shares of a particular class in a company are fully paid up and rank pari passu for all purposes,

Keeping unique share numbers is mandatory, as per Section 45 of the Companies Act, 2013: Numbering of shares:

Every share in a company having a share capital shall be distinguished by its distinctive number: Provided that nothing in this section shall apply to a share held by a person whose name is entered as holder of beneficial interest in such share in the records of a depository.


Numbered shares are not required in Australia if the company issues share certificates which are uniquely distinguished by a number recorded in the register of members. As per CORPORATIONS ACT 2001 - SECT 1070B.


Numbered shares are required and widely used in cap tables and contracts. As per the Article 22 of the Capital Companies Law:

When incorporating a company, the contract must include "the amount each shareholder invests and the numbering of the shares issued in exchange."
