How Do You Read an SIC Code? (What do the two, three, and four Digit Codes Mean?)

Category: Common SIC Questions

The first two digits of the code identify the major industry group, the third digit identifies the industry group and the fourth digit identifies the industry.


Division 20-39 Manufacturing
Major Industry Group 25 Furniture and Fixtures
Industry Group 252 Office Furniture
Industry 2521 Wood Office Furniture

Note: The digit “9” is used in the third or fourth digit position of the classification code to designate miscellaneous industries not elsewhere classified (NEC). These miscellaneous classifications are not comprised of homogeneous primary activity groups. They are grouped together and treated as a separate industry in order to retain the homogeneity of the other industries in the group.
