NAICS & SOC Codes
NAICS, SOC, and SIC Code Reference Charts
North American Industry Classification Systems (NAICS)/Standard Industrial Classifications (SIC) & Standard Occupational Code (SOC) Listings
Systems integration businesses and their employees are often misclassified when filing for a variety of business purposes: tax status, wage classification on job sites, and insurance. NSCA has identified key codes for both the occupation and the industry to help simplify business needs and, in many cases, save significant money. We do not support the use of a classification outside the primary scope of work being conducted by a particular business.
The North American Industry Classification System (NAICS) Codes
The North American Industry Classification System (NAICS) is the standard used by Federal statistical agencies in classifying business establishments for the purpose of collecting, analyzing, and publishing statistical data related to the U.S. business economy. This system replaced the Standard Industrial Classification (SIC) in 1997.
Please note that this code describes industries and does not describe occupations held by people within that industry. (See the SOC table.)

Standard Occupational Classifications (SOC) Codes
The Standard Occupational Classification (SOC) system is used by U.S. government agencies to classify workers into occupational categories for the purposes of collecting, calculating or disseminating data. Please note that this code describes occupations held by individuals and does not describe the industries in which people work. (See the SIC table for that.) We have compiled a partial listing of codes pertinent to the commercial electronic systems industry; for the complete listing of all SOC Codes, visit the Bureau of Labor Statistics.
