NIC Code for the Construction Industry

The construction industry includes diverse activities contributing to the country’s infrastructure growth and urban transformation. For the construction sector, the National Industrial Classification (NIC) Code is a vital tool to accurately categorise businesses engaged in infrastructure development, building construction, real estate, and allied services. Under the Udyam Registration process for micro, small, and medium-sized enterprises (MSMEs), businesses operating in the construction industry must provide the appropriate NIC Code that aligns with their primary economic activity. This page provides information about various NIC Codes for construction activities.
