Corporate Identification Number

A Corporate Identification Number, aka CIN, refers to a unique identification number granted by the RoC, i.e. Registrar of Companies, to the registered companies in India. The Registrar of Companies issues the CIN to the companies while conferring their registration certificate. The CIN serves a company’s identity, and it is mentioned in various forms to be furnished to the MCA, i.e. Ministry of Corporate Affairs, especially in reports and audits.

What is a Corporate Identification Number (CIN)?

Corporate Identification Number is a 21 digits alpha-numeric code granted to the entities incorporated within the nation registered by the ROC of the respective states under MCA.

CIN is generally granted to the following entities in India

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

But, CIN is not accessible to the business structure like LLP in India. The RoC issues the Limited Liability Partnership Identification Number (LLPIN) that serves as a unique 7-digit identification number for such companies.

Significance of Corporate Identification Number

CIN is used to monitor all aspects and activities of an entity from its incorporation by the Registrar of Companies and must be furnished on all the transactions with the respective ROC.

The 21 digit CIN helps determine the company’s basic information listed in the MCA’s database. As a unique number, the CIN can aid in locating or tracking registered entities’ information for various levels that MCA/RoC holds. The CIN entails the organization’s identity and additional details relating to the registered company under the ROC.
