The first character reveals whether a company is listed or unlisted in the Indian stock market. If the company is listed, the CIN will begin with the letter ‘L’, and if the company isn’t listed, it will begin with the letter’ U’.

In the example above: U indicates that the company is unlisted in the stock market.

  • Industry Code

The next five digitsrepresent the ROC industry code. Every activity has a different 5-digit code, assigned by MCA and this code is used to identify the type of company. The MCA has assigned such codes to every industry carrying out its economic activities in India. A few examples are:

  • Hospitals- 85110

In the example above: 12345 refer to the industry code.

The next two letters represent the state code where company’s registered office is situated.

In the example above: DL refers to the state code, i.e., Delhi.

Circumstances under which CIN should be changed for your company

Although ROC issues the CIN in the name of the company when the company is registered, there are times when the CIN has to be updated.

Under the following circumstances, the CIN number may require change:

  • In case of a change in the listing status in the stock market.
  • In case of a change in the state code.
  • In case of a change in the industry code.
  • In case of a change in the ownership status of the company.
