DIR-3 KYC and DIN meaning

By the Autowhat AI team · Updated 2 Nov 2026

What is a DIN and why does a director need one?

Sections 152(3), 153 and 154 of the Companies Act, 2013 require every individual appointed as a director to hold a DIN. It is a lifetime number: one person gets one DIN, and it follows them across every company they join. A director quotes it in every ROC form they sign, from DIR-12 for appointments to the annual return. For a new company, DINs for the first directors are usually allotted through the incorporation form; for later appointments, the individual applies for one before taking office.

A DPIN is the equivalent number for a designated partner of an LLP, and since the two were unified, the same DIN can serve both roles.

What is DIR-3 KYC?

DIR-3 KYC is how MCA keeps director records current. Under Rule 12A of the Companies (Appointment and Qualification of Directors) Rules, 2014, every person holding a DIN confirms their KYC details on the MCA V3 portal, with OTP verification on their personal mobile and email.

The rule changed recently. Under the earlier rule, every DIN holder filed each year by 30 September. MCA has since amended the rules to move this to a single DIR-3 KYC Web filing once every three consecutive financial years, with changes in mobile, email or address to be updated separately when they happen. Read the notification text on the MCA portal for the exact due date and update window before advising a director, since practices may still see the older annual dates in templates and calendars.

What happens if DIR-3 KYC is not filed?

MCA marks the DIN as deactivated for non-filing of KYC. A deactivated DIN cannot be used to sign or be quoted in forms, which can block a company's own filings if that director is the signatory. The DIN is reactivated once the KYC is filed with the prescribed fee; confirm the current fee on the MCA portal.

How does this play out in a practice?

Illustrative example. A CS practice looks after 25 companies with 60 board seats between them, held by 45 individuals. Some directors sit on several boards, but each holds one DIN, so the practice has 45 KYC filings to plan, not 60. Before the KYC window the practice lists every DIN, checks which ones are due in the current cycle, and confirms that each director's mobile and email are still their own, since OTPs go there. One director changed phone numbers last year and never updated it: that one needs a change update first.

AutoROC, MCA e-form filing software for CS firms, shows director KYC next to each client's annual and event-based filings on one dashboard, with days left, and validates DIN and PAN on entry. For the full flow on V3, see the MCA V3 e-form filing workflow, and for planning the season, the ROC compliance calendar.

What do people confuse about DIN and KYC?

• DIN vs DSC. A DIN identifies the director; a digital signature certificate is the tool used to sign forms. Both are needed.
• One KYC per DIN, not per company.
• Using a staff member's mobile or email. OTPs and notices go there, and it must be the director's own.
