Reserve Unique Name: submit proposed company name, provide CIN if change, attach approvals for CRC review. The statutory name-reservation procedure requires applicants to select entity type, provide the proposed name and CIN if seeking a change of name, and attach sectoral regulator approvals or NOCs where applicable. The older INC-01 form was substituted by the RUN form effective 23 March 2018; once submitted, the Central Registration Centre checks feasibility and issues electronic notice of the reservation outcome.
