Importance Of Corporate Identification Number

A Corporate Identification number, however, is not just a formality; it has several functions in the business world. Out of many, the following are a few important aspects of a CIN. 

Legal Identification: A CIN is the legal identity of a company in India. Every company incorporated in India must obtain a CIN during the business registration process. Without a CIN, a company cannot conduct its business operations or enter into legal contracts. 

Regulatory Compliance: A CIN helps track the activities of the respective business, which, in turn, helps the authorities ensure that companies adhere to the legal framework. 

The 21-digit CIN is an alphanumeric code, and these 21 digits have a clear meaning that is easy to translate and helps in filing basic information about the company. It is generally used to obtain the primary details of a company registered with the MCA. 

Prevent Fraud: Since CIN ensures that companies operate within their designated legal structure, and business services. This way, CIN helps in eliminating fraudulent activities proactively. 

Corporate Data Access: CIN is the key to corporate data. It provides seamless access to the company's official documents, financial statements, and other important information through the MCA portal. This access is crucial for competitors, investors, and the regulatory bodies. 

Corporate Identification Number Breakdown. 

As noted above, the 21 digits of the CIN provide crucial information about the company. The CIN is generally broken into six sections, as follows. 

An Example Of A Unique CIN: L01631KA2010PTC096843. 

  • Section 1: The first character is L. 
  • Section 2: The next five digits - 01631.
  • Section 3: The next two letters - KA. 
  • Section 4: The next four digits - 2010. 
  • Section 5: The next three characters - PTC. 
  • Section 6: The last six digits - 096843. 

Let us see what information each section of the CIN denotes. 

Section 1

The first letter of the CIN indicates whether the company is listed or unlisted on the Indian stock market. If the company is listed, the CIN will start with L; if it is not listed on the Indian Stock Exchange, it will start with U. 

Section 2

Section two is the set of five numbers that denote the economic activity of the company or the particular industry to which it belongs. These numbers typically reflect the nature of the company's economic activities, which it would carry out. The MCA (Ministry of Corporate Affairs) has issued a number to every industry or category. 

Section 3

Section three lists the next two letters indicating which state the company is registered in. For example, MH is for Maharashtra, DL for Delhi, and KA for Karnataka. It is similar to the car registration number, denoting the state with two letters. 

Section 4

Section four contains our set of four numbers, which classify the company's year of incorporation. 

Section 5

If, in the CIN, these three letters are "FTC", it means that the company is operating as a subsidiary of a foreign company. If the letters are "GOI," it means the company is owned by the Government of India.

The remaining six numeric digits denote the company's registration number, issued by the Registrar of Companies (ROC).
