Every person who has been allotted a Director Identification Number must submit DIR-3 KYC each year, ordinarily by 30 September, confirming identity, address and mobile / e-mail, with OTP authentication. If it is not filed, the DIN is marked deactivated for filing, which then blocks the company’s other forms. It is a personal filing of the director, not of the company, though companies usually shepherd it. See the calendar and ROC annual filings.
