During the industrialization of our Great Nation, entrepreneurs didn’t have the technology we have today for business analysis, data mining, or marketing. Some industries such as lumber, coal, and other fuels just did exceptionally well because those resources were in high demand. Imagine the entrepreneur selling lumber Kansas or Nebraska to the railroads or some of its passengers. It was a no-brainer for them. Their product was in high demand. This was a beautiful thing back in the day. Imagine the satisfied looks on industrial captains such as Firestone, Mellon, J.P. Morgan, and Rockefeller. They didn’t need marketing analysis. The just needed more products for the insatiable appetite of a booming nation.
Big Brother felt it their duty to keep track of all this. As industrialization gained momentum during the early 1900s, various departments of the U.S. government initiated research and studies on the various industries and their different functions. The aim was to consolidate information to come up with important decisions about necessary facilities, investments and regulations to further support the industrial growth. However, due to the lack of set standards, each department ended up using its own methodology. Consolidating information across multiple sources became a challenge. The Standard Industrial Classification (SIC) was hence proposed as uniform classification system, aimed to represent major industries, sub-class and specific function/product and was formally adopted in 1937.
> How do SIC Codes Work?
Depending upon the industry group, product or function, SIC codes were designed such that one single SIC code can apply to multiple firms and companies. For example, SIC code “0115” indicates multiple details and categorizations as follows:
Depending upon the industry group, product or function, SIC codes were designed such that one single SIC code can apply to multiple firms and companies. For example, SIC code “0115” indicates multiple details and categorizations as follows:
a.) First 2-digits “01” indicates the major group (“Agriculture Production – Crops”)
b.) First 3-digits “011” indicates industry sub-group (“Cash Grains”) which includes wheat, rice, corn, etc.
c.) The entire 4-digit code “0115” indicates a specific product group (“corn”)
If any research related data is tagged with the above 4-digit code, it becomes easy to classify data at various levels. For example: What was the total production of all agricultural crops in 2016 in Kansas? Simply pull records matching the first 2-digits of SIC codes as “01” (or 4-digit SIC code = “0100”) and state = “Kansas” and year = “2106”.
In another example, how many businesses operate in “cash grains” segment (which includes wheat, corn, soybeans, etc.) in Canada? Simply pull records matching first three SIC code digits as “011” (or 4-digit SIC code = “0110” and county = Canada.
To know how many companies are registered in Texas producing corn, one simply needs to generate the report which has the 4-digit SIC code “0115”.
> Use and Benefits of SIC Codes:
The structural hierarchy of SIC codes starts with the broad industry type 2-digits, further narrowing to sub-industry 3-digits, and finally pointing to specific specialization 4-digits. Using the same SIC code “0115” for corn, two data gatherers, one surveying farms in the countryside about how much corn has been sown by farmers for the coming season, and another at the local market tracking the sale price of corn, supply and demand of current corn produce, were able to consolidate their data uniformly. Use of these standard SIC codes facilitated easy reporting, data analysis and decision making for future investments and other necessary support.

> Challenges with SIC Codes:
Although extremely useful at the start, they ran into issues of mismatches, overlapping and ambiguous descriptions and their limited scope of classification code availability (due to only 2-digits, followed by one digit for each additional category). That constrained the scope of adding new emerging industries and functions.

That constrained the scope of adding new emerging industries and functions.
In 1997, SIC codes were further expanded to NAICS (North American Industrial Classification System), which were 6-digits ling and offered more scope for adding various new industries and functions, as well as clearing ambiguous codes. Here is the same example of the corn farming industry, progressively indicating what a 6-digit NAICS code represents:
a.) First 2-digits “11” (Agriculture, Forestry, Fishing, and Hunting)
b.) First 3-digits “111” (Crop Production)
c.) First 4-digits “1111” (Oilseed and Grain Farming)
d.) First 5-digits “11115” (Corn Farming)
e.) 6-digits “111150” (Corn Farming)
In essence, the SIC codes and NAICS codes are similar. NAICS offers more room and flexibility for accommodating more classification and functions. SIC codes and NAICS codes can be used in tandem. While SIC continues to remain popular for traditional businesses and industries like manufacturing and crop produce, NAICS codes are finding more usage in newly developed segments and industries like technology, due to extended availability with extra digits in the codes. Both find usage in marketing, business listing and analysis functions.
A full list of SIC codes can be found at U.S. Department of Labor’s website and SIC Manual section, while NAICS details are available at the U.S. Census website. These websites also offer sections on how to search SICS and Search NAICS codes. Besides these, there are other sources on the internet offering free SIC and NAICS codes like http://www.siccode.com
Regardless of what business venture you are setting up, industry classification is a necessary requirement at local, regional, and national levels. SIC and NAICS offers the necessary classification codes, making it easy for business analysis, marketing, business listing, data mining and investment decisions for your company. This is an excellent tool I highly recommend to all entrepreneurs.
