North American Industry Classification System (NAICS) is an industry classification system that groups 
     establishments into industry sectors based on the activities in which they are primarily engaged. The
     NAICS is a comprehensive system covering the entire field of economic activities, producing and
     non-producing. This system replaces the former Standard Industrial Classification (SIC) designations.
     Corporate America and local, state, and federal government entities use NAICS codes. You are required
     to identify your business NAICS designation code.
