Director identification number (DIN) is a unique identification number given to a person wanting to be a director or an existing director of a company. In this digitised era, application in eForm DIR-3 was sufficient to obtain DIN. This was a one-time process for any person who wants to be a director in one or more companies. However, now with the move of the Ministry of Corporate Affairs (MCA) to update its registry, all directors with a DIN will have to submit their KYC details annually in eForm DIR-3 KYC.
