I was introduced to SIC code when I tried to find what BDC code was. SIC stands for “Standard Industrial Classification” and BDC stands for “Business Directory Codes”.
They are both coding system used to classify business. The difference between them is that BDC is a proprietary coding system developed by Acxiom.
Acxiom is an information management company and it is a public company traded in NASDAQ. BDC is an eight digit coding system. SIC code is a coding system developed by United States government for classifying industries and it is a four digit coding system. Some companies append two or four additional digits to the standard SIC code to form a six or eight digit SIC code, allowing more specific business classification. D&B is one of the companies that develop eight digit SIC code.
D&B is also a public company listed on NYSE. I am supprised that both D&B and Acxiom are multi-billion dollar companies.
The D&B SIC system is divided into five levels:
Main Division - Indicated by letters A-K
2-digit SIC codes - Major groups within the main divisions
4-digit SIC codes - Specific industries within the major groups
6-digit SIC codes - Sub-industries within the specific industries
8-digit SIC codes - Lines of business within the sub-industries
BDC system has similar structure. I found that it is pretty hard to find a complete list of 8 digit SIC code on the internet so I have gathered information on the internet and compile a complete list of SIC Code and description for you to download.

Wow - thanks for the SIC Code spreadsheet. You are right on the money that it’s hard to find these in this form anywhere on the internet.
This is great! Thank you very much!
There is really no excuse for census.gov and OSHA to NOT publish this stuff in excel spreadsheets. It’s a no-brainer.
Thanks!

This was almost good. You have dupes in your list. That makes the spreadsheet somewhat less than useful.
