Federal Principal Business Code: History
It was in the year 1934, that The U.S. Office of Statistical Standards came up with the idea of grouping companies based on categories. It took nearly four years for the idea to be materialized. In 1938, Standardized Industry Classification codes (SIC) was launched. It was the first list of businesses classified by industry type. Further, it was in 1941 that the first complete edition of SIC codes was launched. For nearly 50 years, these SIC codes were used as a primary source of business classification. In 1997, however, owing to the efforts of the U.S. Census Bureau, the new North American Industry Classification System, or NAICS, was introduced and it gradually replaced the old SIC codes. NAICS codes are of six digits and they contain one extra digit for more specific classification and another extra digit for country classification. Compared to NAICS, SIC codes only represented business codes for only US. So you can also visit the NAICS official website to know the principal business code for your businesses.
