A Company Number is the unique identification number issued to your company on its incorporation by the companies’ registry in its jurisdiction of incorporation. You can find the Company Number on your Company’s Certificate of Incorporation and on your company’s listing at the companies’ registry.

Depending on your company’s jurisdiction of incorporation, the Company Number will be a numerical only code, or an alpha-numerical code. It may vary in length, for example, from 8 digits in England and Wales to 21 digits in India.
