Corporate Identity Number (CIN) is a unique 21-digit alpha-numeric identifier that is assigned to every company incorporated in India. It is assigned by the Registrar of Companies (ROC) at the time of company registration.
The CIN contains information about the company such as its industry code, state of registration, date of incorporation, and the type of company it is (private, public, etc.). The first two characters of the CIN indicate the type of company, the next eight characters indicate the state of registration, the next six characters indicate the date of incorporation, and the last five characters are randomly generated.
