Company Registration Number in India: A Complete Guide

The company registration number, known as the Corporate Identification Number (CIN) in India, is a unique 21-digit alphanumeric code assigned to companies registered under the Companies Act, 2013. It serves as a legal identifier for private limited, Section 8, Nidhi, or other companies, ensuring transparency and compliance. This blog provides a comprehensive guide on the company registration number, explaining its structure, how to obtain and verify it, and its role in compliance, with insights on how TaxQue simplifies the process.

The company registration number (CIN) is issued by the Registrar of Companies (ROC) under the Ministry of Corporate Affairs (MCA) upon company incorporation. It uniquely identifies a company’s registration details, including its type, state, and incorporation year. The CIN is essential for regulatory filings, compliance checks, and stakeholder verification, making it a cornerstone of corporate governance.

The company registration number (CIN) comprises 21 digits, broken down as:

• First Character: Listing status (L for listed, U for unlisted).
• Next 5 Digits: Industry code (e.g., 67120 for Nidhi companies).
• Next 2 Characters: State code (e.g., MH for Maharashtra).
• Next 4 Digits: Year of incorporation (e.g., 2025).
• Next 3 Characters: Company type (e.g., PTC for private limited, NPL for Section 8).
• Last 6 Digits: ROC registration number (e.g., 123456).
  Example: U67120MH2025PTC123456 (unlisted private limited company in Maharashtra, incorporated in 2025).

Obtaining a company registration number is part of the company incorporation process:

• Step 1: Get DSC and DIN: Directors need a Class 3 DSC for e-signing and DIN via SPICe+ (Form INC-32) on the MCA portal.
• Step 2: Reserve Name: Use SPICe+ Part A (RUN) to reserve a name (e.g., “Nidhi Limited” for Nidhi companies).
• Step 3: File SPICe+: Submit SPICe+ Part B with MoA, AoA, and director details (PAN, Aadhaar, address proof).
• Step 4: Receive CIN: Post-approval (5–7 days), the ROC issues the Certificate of Incorporation with the CIN, PAN, and TAN.
• Nidhi/Section 8: File Form NDH-4 (Nidhi status) or INC-12 (Section 8 license) before or after SPICe+.
