An Overview of CIN or Corporate Identification Number

A Corporate Identification Number (CIN) refers to a unique number allotted to the company registered by the RoC. The CIN comes along with the registration certificate issued by the RoC. The RoC stands for the Registrar of Companies. RoC reserves exclusive power for legalizing entities under the Companies Act 2013.

The Corporate Identification Number helps governing authorities and other parties establish the company’s identity easily. During a compliance audit, registered companies are obligated to share CIN with the concerned authority i.e. MCA (Ministry of Corporate Affairs).

What information does Corporate Identification Number enclose?

CIN encloses the 21-digit alphanumeric code that provides the following information about the company

  • Listed or unlisted on the stock exchange
  • Year of incorporation
  • Legal structure (whether the entity falls under the Companies Act 2013 or LLP Act 2008, or Partnership Act 1932, etc)
  • Registration number

Which companies can have a Corporate Identification Number (CIN) in India?

Corporate Identification Number (CIN) is technically a 21-digits code comprising alphabets and numbers. Registrar of Companies (RoC)  grants CIN to the registered entities falling under the ambit of the Ministry of Corporate Affairs (MCA).

CIN is essentially granted to the following types of entities in India:

  • Private Limited Companies
  • One-Person Companies
  • Companies falling under the GOI
  • State Government Companies
  • Section 8 Companies
  • Nidhi Companies, etc.

However, firm like LLPs (Limited Liability Partnerships) does not have access to CIN.  Instead, these firms are provided with the LLPIN (Limited Liability Partnership Identification Number) accorded by the ROC. It is a 7-digit code that helps establish LLP’s identity.

What is the Significance of a Corporate Identification Number?

CIN keeps track of the company’s undertakings and aspects. It is required to be enclosed in all the transactions relating to the Registrar of Companies (RoC).

Being easily interpretable, the 21-digit code of Corporate Identification Number help establish fundamental details concerning the company. It is utilized for discovering companies' details available with the Ministry of Corporate Affairs.

CIN encloses the details that any third party, entity, or investor can use to know about the company and its legal structure. Keep note that it does not have any details that fall outside the MCA’s ambit.

Understanding the code of Corporate Identification Number

The 21-digits CIN renders information about the MCA-registered company, which further can be bifurcated into the following sections. To understand what CIN implies, let’s take the above CIN as an example: U74140TN2011PTC082268.

Section-1: The first character – U

Section-2: The next five digits – 74140

Section-3: The next two letters – TN

Section-4: The next four digits – 2011

Section-5: The next three characters – PTC

Section-6: The last six digits – 082268

Let’s explore each section to discover what they imply:


The First letter implies whether an entity is listed or unlisted. Simply put, it showcases the Stock Market listing status of the company. The letter U denotes that the company is yet to be listed on the stock market- meaning it is an unlisted entity.


This section entails five numbers that denote the niche or the industry which the company serves. The MCA uses this to classify companies based on the nature of economic activities.


This section entails two alphabets that imply the state name in which the company resides. In this example- the letter TN stands for Tamil Nadu.

Section 4

This section comprises the four numbers that show the incorporation year of the company.


This section entails three alphabets that help identify the legal structure of the company. These letters help recognize whether an entity is OPC, a private ltd company, or a public limited company. In this example, the PTC stands for Private limited company.


The last six numbers in this section serve as a registration number, which is issued by the ROC alongside the registration certificate.
