Corporate Identification Number (CIN)

Meaning & Definition

The Corporate Identification Number (CIN) is a 21-digit number made up of both letters and numbers, used to uniquely identify all companies registered in India. It was assigned by the Registrar of Companies (RoC) when the company was incorporated, helping to establish a company’s ownership structure, type of company, year it was incorporated, the state in which it was registered, and a unique identification number.
