Director Identification Number establishes government allotment and provisional electronic issuance for director identification under company rules. A Director Identification Number (DIN) is an identification number the Central Government may allot to individuals intending to be appointed as directors or to existing directors for identification. The rules designate the prescribed form, define 'Pre-fill' as automated data input from the electronic registry, and recognise a Provisional Director Identification Number generated by the Ministry's online system after submission via the Ministry of Company Affairs portal.
