Following submission of the application and the documents for incorporation and registration, the companies are to be provided a unique 21-character number of their registration identification by the Registrar of Companies, the Company Registration Number (CRN), also referred to as Corporate Identification Number (CIN). ROC keeps track of every business that receives a CIN, or company registration number.

Therefore, every company in India must get a CIN registration number. The focus of this article is to define the company registration number, the process of creating it, and the importance associated with the CIN. 

About Company Registration Number

• The registrar of companies in the Ministry of Corporate Affairs assigns a unique 21-character alphanumeric identification called the company registration number, or corporate identification number (CIN).  
• It is a formal identity for a company given in connection with the government database for administrative, finance, and legal purpose.

How is Company Registration Number Created?

• The status of a company-listed or otherwise-is determined by the first letter of the CIN registration code. If the first letter is “U,” the company is unlisted. If it is “L,” the company is listed and not otherwise.
• This is followed by five digits that are intended to signify the specific industry the company relates to and what activities it performs.
• The next two digits of the CIN signifies the state the company was originally registered in-with each state having its own unique code. For example, the state of registration could be put as RJ if the company is incorporated in the state of Rajasthan. 
• The next four-digit registration number shows the year of the company’s incorporation.
• CIN is a company registration number assigned by the registrar of companies, whose last six digits comprise the unique identification number for the company.  It sets the business apart from other registered entities and its official identifying number.

Why is Company Registration Number (CIN) Important?

• Legal Identity: It attests to the business’s registration and legal recognition in India.
