Common SIC Questions
The Standard Industrial Classification System (SIC) was discontinued in 1997. While the four digit SIC codes will no longer be updated, some data companies have created a proprietary 6 or 8 digit SIC coding system that they continue to maintain and update for market segmentation purposes. When you look at a 4 Digit SIC code page on our website, you will see the 8 Digit SIC codes as produced and maintained by Dun & Bradstreet. You are not able to have new codes created, but D&B does update and maintain these codes and will produce new codes when they determine there is enough evidence that the new code is warranted.
