How to Check CIN Number Online in India: A Complete Guide

India’s corporate ecosystem runs on legal transparency and regulatory accountability. The Corporate Identification Number (CIN) is central to this framework, serving as a 21-character unique identification code issued by the Registrar of Companies (RoC) under the Companies Act, 2013. More than 1.5 million registered companies in India in 2025, verifying that a CIN number check is essential for due diligence, compliance validation, business contracts, and investment decisions.

Understanding how to check a CIN number online helps verify whether a company is legitimate, active, and compliant with filings on the MCA portal. Whether you’re an entrepreneur, investor, or stakeholder, mastering where to check CIN and how to decode its structure protects businesses from fraud. It also improves decision-making for entrepreneurs, investors, and stakeholders.

What is a CIN (Corporate Identification Number)?

A Corporate Identification Number (CIN) is a 21-character alphanumeric code issued by the RoC under the Ministry of Corporate Affairs (MCA). This unique code acts as the official identity number for registered companies in India. Additionally, it helps track a company’s incorporation details, industry code, and RoC jurisdiction.

Key Features of CIN

CIN is assigned only to registered companies like Private Limited Companies (Pvt Ltd), Public Limited Companies, One Person Companies (OPC), Section 8 Companies, etc.

• It is mandatory for annual filings, audits, tax submissions, and government approvals, making the CIN number search crucial for compliance.
• It reflects the company’s legal identity and remains consistent unless structural changes occur.

CIN remains unchanged unless there are major structural modifications, such as conversion from private to public or shifting to a different RoC jurisdiction. Read more about Section 18 of the Companies Act, responsible for private to public conversion.
