A company is an artificial person and a separate legal entity different from its members and directors. It can enter into contracts on its own, purchase a property in its own name, can sue third parties, etc. Therefore, it has a separate identity. A Corporate Identification Number, commonly known as CIN, is a unique number that you can use to identify a company. Every company registered in India has a CIN. In this blog, we will understand the meaning of CIN and the importance of CIN for a company.  

What is a CIN?

A Corporate Identification Number or Corporate Identity Number is a 21-digit unique number or code. The Registrar of Companies (ROC) issues this code to all the companies registered in India. This code is a combination of alphabets and numbers. It is used to track information about a company.
