Decoding of CIN number
CIN number is divided into 6 sections which are explained below with sample CIN number:
U 12345 DL 2020 PLC 098765
- U: List status
- 12345: Industry code
- DL: State code
- 2020: the year of registration
- PLC: Proprietary
- 098765: Registration number
The first section shows the status of the company in the list. If the company is listed then the alphabet will be “L” and if the company is not listed the status will be “U”. The next section or 5 digits represent the industry code. A company doing business in any industry is assigned a unique industry code by the ROC. The next two digits represent the state code in which the company was registered with the Registrar of Companies and its legal address is the specified state. The state code is followed by the company’s year of incorporation, which uses the 4 additional digits in the CIN number. The next three numbers indicate the type of company: Private or Limited Company, Government of India, Non-Profit, Sole Proprietorship or State Government Company. The last 6 digits represent the company’s RoC code, and all these elements together form a 21-digit unique CIN number.
Note: A limited liability partnership (LLP) does not use a CIN. They are provided with an LLPIN.
