What Is a Corporate Identification Number (CIN)?

A Corporate Identification Number or CIN number is a 21-character alpha-numeric code assigned to companies registered under the Registrar of Companies in India. It acts as a unique identifier, reflecting details like the type of company, its state of registration, and year of incorporation.

A CIN is provided to all companies registered in India, including:

• Private Limited Companies (PLCs)
• One Person Companies (OPCs)
• Companies owned by the Government of India
• State Government Companies
• Not-for-Profit Section 8 Companies
• Nidhi Companies, etc.

In contrast, Limited Liability Partnerships (LLPs) are assigned an LLPIN (Limited Liability Partnership Identification Number). The CIN plays a vital role in company identification and compliance with legal obligations.

Importance of Corporate Identification Number

The CIN is critical for identifying and tracking a company’s activities from its incorporation. Assigned by the Registrar of Companies, it ensures every registered company has a distinct identity under the Ministry of Corporate Affairs. This 21-character alpha-numeric code provides key details, such as the company’s registration type, state, and year of incorporation.

For example, a typical CIN might look like U12345MH2024PLC567890, where each segment represents specific company details.

The CIN must be included in all filings, audits, and reports submitted to the ROC or MCA. It is essential for verifying company information during legal and financial transactions, offering transparency and credibility. The CIN acts as the foundation for company identification, ensuring compliance with Indian business regulations.

Breaking Down Corporate Identification Number

A CIN is a 21-character alphanumeric code that reveals key details about a company. It is structured into six sections, each offering specific information that aids in company identification and regulatory tracking by the ROC and the MCA. Here’s a breakdown:

Section-1: Listing Status

The first character indicates whether a company is “Listed” or “Unlisted” on the stock market.

• L: Listed on the Indian stock exchange.
• U: Unlisted.

Section-2: Industry Classification

The following five numeric digits represent the company’s primary economic activity or industry. The MCA assigns each category of economic activity a specific code. For example, 12345 could signify a particular industry, such as technology or healthcare.

Section-3: Registration State

The following two letters identify the state where the company is registered. Examples include:

• TN: Tamil Nadu
• GJ: Gujarat
• UP: Uttar Pradesh

This section functions similarly to state codes in vehicle registration numbers.

Section-4: Year of Incorporation

The next four numeric digits represent the company’s year of incorporation. For example, "2015" signifies that the company was established in 2015.

Section-5: Company Classification

The following three characters indicate the company type. Examples include:

• PLC: Public Limited Company
• NPL: Not-for-Profit Organisation
• SGC: State Government Company

Section-6: Unique Registration Number

The last six digits are the company’s unique registration number, assigned by the ROC to distinguish it from other entities.

CIN number example: U12345TN2015PLC789101

This example shows an unlisted company (U) operating in a specific industry (12345), registered in Tamil Nadu (TN), incorporated in 2015 (2015), classified as a public limited company (PLC), with a unique registration number of 789101.

Abbreviations in CIN Number

The abbreviations used in Section 5 of the CIN include:

• FLC: Financial Lease Company as Public Limited.
• FTC: Private Limited Company Subsidiary of a Foreign Company.
• GAP: General Association Public.
• GAT: General Association Private.
• GOI: Government of India-owned companies.
• NPL: Not-for-Profit License Company.
• PLC: Public Limited Company.
• PTC: Private Limited Company.
• SGC: State Government-owned Companies.
• ULL: Unlimited Liability Limited Company.
• ULT: Unlimited Liability Trust.

Usage of Corporate Incorporation Number

The CIN is essential for ensuring compliance and maintaining legitimacy. It must be used in the following:

• Invoices: To identify the company in financial transactions.
• Notices: For official communication with stakeholders.
• Letterheads: To reflect the company’s legal identity in correspondence.
• Annual Reports: As a mandatory disclosure for regulatory purposes.
• MCA e-forms: To ensure accurate filing with the Ministry of Corporate Affairs.
• Publications: For transparency in public-facing materials.

Using the CIN correctly ensures smooth corporate communication and compliance with Indian legal requirements.

Penalty for Non-Compliance of Mentioning CIN Number

Failing to comply with the requirement of mentioning the CIN on official documents can lead to significant penalties. If the requirements are not met, the defaulting company and its officers in default face a penalty of ₹1,000 per day, continuing until the non-compliance is rectified. The maximum penalty for such defaults is capped at ₹1,00,000. These penalties ensure strict adherence to regulatory norms and maintain transparency in corporate operations.

Changing Corporate Identification Number

You cannot directly change the Corporate Identification Number (CIN), but it automatically updates when specific changes occur in your company’s status or structure. These changes include:

• Listing Status: The CIN updates automatically if your company transitions from private to public or is delisted. For example, a Private Limited Company converting into a Public Limited Company will update its CIN to reflect the new listing status.
• Registered Office Location: Moving your company’s registered office to another state will result in an updated CIN to match the new state code. For example, if your company relocates its registered office from Maharashtra to Karnataka, the CIN will change from 'MH' to 'KA'.
• Industry or Sector: A change in your company’s primary business activity will update the industry classification in the CIN. For example, a company shifting from software services to financial services will modify its CIN to reflect the new industry.

Limited Liability Partnership (LLP)

An LLP is a hybrid business structure that combines the benefits of a company (limited liability) with the flexibility of a partnership. Some key features include:

• Minimum two partners required
• Liability of partners is limited to their contribution
• No minimum capital requirement
• Fewer compliance requirements than a company
• Separate legal identity from its partners

One Person Company (OPC)

Introduced under the Companies Act, 2013, an OPC allows a single individual to operate a corporate entity. It offers:

• Limited liability
• Separate legal identity
• Easier fundraising compared to a sole proprietorship
• Greater credibility in business dealings

However, OPCs face limitations like:

• Restrictions on fundraising
• Mandatory conversion if turnover exceeds ₹2 crore or capital exceeds ₹50 lakh
• Cannot have more than one member

Conversion of OPC to LLP

OPC conversion to LLP is governed by the Companies Act, 2013 and the Limited Liability Partnership Act, 2008. While direct provisions for OPC-to-LLP conversion are not explicitly provided, companies (including OPCs) can be converted into LLPs under Section 366 of the Companies Act and the Second Schedule of the LLP Act.

Understanding the Legal Provisions for Conversion of OPC to LLP

The legal path for converting an OPC to an LLP involves:

• Section 366 of the Companies Act, 2013 (deals with companies being converted into LLPs)
• Second Schedule of the LLP Act, 2008 (provides the procedure for such conversions)
• Form FiLLiP and Form 18 under the LLP Rules, 2009

Note: Prior approval from the Registrar of Companies (ROC) is mandatory.
