What Is a CIN Number? Meaning and Importance Explained

Every lawfully registered Indian company is given a unique Corporate Identification Number (CIN) by the governing body that oversees company establishment (the ROC), similar to how the Indian government issues Aadhaar cards for identification.
This alphanumeric code, consisting of 21 characters, is the exclusive identification of a company. It enables the government, investors, and owners to ensure compliance with Indian corporate law. Read on as we explore the CIN number, its formation, and its significance.
 

What Is a Company CIN Number?

 The CIN number is a 21-digit alphanumeric code. All companies registered in India are allotted one CIN. The ROC issues it at the time of company registration and uses it to track company activities.
This number contains various company details, such as listing status, industry code, state of registration, year of incorporation, company type, and a unique registration number.
CIN is typically issued to:
●    Private Limited companies (PTC)
●    Public Limited companies (PLC)
●    Government companies
●    Section 8 not-for-profit companies
●    Nidhi companies
Interestingly, LLPs do not get a CIN, but an LLPIN (Limited Liability Partnership Identification Number).

Structure of CIN Number: Breaking Down the 21 Digits

The CIN is a 21-digit alphanumeric number that contains key company details, explained as follows:

H3: Section 1: Listing Status (L/U)

This is the first letter in the CIN, and highlights whether a company is Listed (L) or Unlisted (U) on the stock exchange.

Section 2: Industry Code (5 digits)

A five-digit industry code represents the company's primary economic activity according to its official classification.

Section 3: State Code (2 letters) 

State code is a set of two letters that represents the state where the company is registered (for instance, MH indicates Maharashtra). 

Section 4: Year of Incorporation (4 digits) 

The company’s incorporation year is represented by the four digits.

Section 5: Company type (3 letters)

The three letters you see in the CIN (such as PTC or PLC) represent what type of company it is.

Section 6: Registration Number (6 digits)

The last part of the CIN is a 6-digit registration number. It is a unique number assigned to the company by the Registrar of Companies (ROC).
Each part of the CIN can thus be used to glean various types of information about a company.
