Company Registration Number
A Company Registration Number (CRN), referred to as the Corporate Identification Number (CIN) in India, is a unique 21-character alphanumeric code issued by the Registrar of Companies (ROC) under the Ministry of Corporate Affairs (MCA) after a company is successfully incorporated. It acts as the company’s official identifier and contains information related to its category, year of incorporation, state of registration, industry, and ROC.
The Company Registration Number in India establishes a company’s legal identity and is required for filing annual returns, submitting financial statements, and carrying out transactions with government authorities, banks, and other stakeholders. The CIN appears on the Certificate of Incorporation and generally remains unchanged throughout the company’s existence, even if its name or directors change.
