Corporate Identification Number (CIN)

A Corporate Identification Number (CIN) is a unique identification number that is assigned to all companies registered in India. CIN is an important number as every company must mention this unique CIN in the forms to be submitted to the Ministry of Corporate Affairs (MCA), particularly in audits and reports.

Key Highlights:

  • CIN is a 21-digit unique identification number of companies in India.
  • The ROC issues the CIN at time of registration of companies.
  • It is used for tracking the activities of a company by ROC.

What is Corporate Identification Number (CIN)?

Corporate Identification Number (CIN) is a 21 digits alpha-numeric code issued to companies incorporated within the country by the by the Registrar of Companies (ROC) situated in different states across India under the MCA. The ROC gives the CIN to the companies while issuing their Registration Certificate.

CIN is provided to all companies registered in India, which include:

However, CIN is not given to the Limited Liability Partnerships (LLP) registered in India. For the LLPs, the ROC gives the LLPIN (Limited Liability Partnership Identification Number) that acts as a unique 7-digit identification number of the LLP. 

Breaking Down Corporate Identification Number

The 21-digits CIN represents and provides information about the company. The CIN can be broken down into six sections. 

Example of a unique CIN issued by ROC – L01631KA2010PTC096843

In the above example, the CIN can be broken down as follows:

Section-1: The first character – 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

Each section provides the following information:

Section-1: 

Consists of the first character of CIN that reveals whether a company is “Listed” or “Unlisted” on the Indian stock market. In other words, the first character implies the Stock Market listing status. In case a company is listed, the CIN would start with the letter ‘L’ and in case a company isn’t listed it would start with the letter ‘U’.

Section-2: 

Consists of the next set of five numeric digits that categorizes the economic activity of a company or to which industry the company belongs to. This classification is based on the nature of the economic activities which would be carried out by such an establishment. The Ministry of Corporate Affairs (MCA) has allotted a number to every category or industry.

Section-3: 

Consists of the next two letters that denote the Indian state where the company is registered. For instance, KA is for Karnataka, MH is for Maharashtra, DL is for Delhi, etc. It works in a similar fashion as the car registration number.

Section-4: 

Consists of the next set of four numeric digits that signifies the year of incorporation of a company.

Section-5: 

Consists of the following three letters that denote the company classification. These three letters help to identify whether a company is a private limited company or a public limited company. If the CIN number here is FTC, it would mean that such a company is a subsidiary of any foreign company or if it’s GOI, it would imply that such company is owned by the Indian Government.

Section-6: 

Consists of the remaining six numeric digits that denote the registration number provided by the respective Registrar of Companies (ROC).
