A director identification number DIN is a unique identifying number assigned to a person who wishes to become a director or is already a director of a corporation. DIN is obtained by submitting an application in eForm DIR-3, which was originally intended to be a one-time process for anyone wishing to become a director of one or more companies. However, as a result of an amendment to MCAs register, all directors with DIN are now required to submit their KYC details in e-Form DIR 3 KYC every year.  Every director shall inform all the companies in which he or she is a director, of the DIN allotted to him or her in Form DIR-3B within 30 days of the receipt of intimation of approval of DIN. Similarly, the Secretary and Manager of a company shall inform the company of their Income-tax Permanent Account Number PAN. The company needs to further information about the DIN of the directors to the Registrar in Form DIR-3C within 15 days of receiving the intimation.
Any DIN holder who has already submitted eForm DIR-3 KYC in any of the previous financial years and who does not require an update in any of his KYC details as submitted may perform his annual KYC by accessing the DIR-3 KYC web service.
