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.

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.
