Director Identification Number verification and cancellation framework tightened through prescribed compliance, deactivation, surrender, and restoration conditions. Director Identification Number verification requires submission of particulars to the Central Government or an authorised officer at prescribed intervals and in the prescribed manner. Non-compliance, improper allotment, or director disqualification may lead to deactivation or cancellation of the Director Identification Number. A deactivated Director Identification Number prevents the holder from functioning as a director, while cancellation makes the office vacant. A Director Identification Number may also be surrendered, and a deactivated, cancelled, or surrendered number may be reactivated or restored on fulfilment of prescribed conditions and payment of prescribed fees.
