What is the difference between the PSC, SIC, and NAICS codes?
Each acronym represents a code for products bought by the government. Product Service Code (PSC) is a code for items that are sold to the federal government, while the Standard Industrial Classification code (SIC) is a classification for products traded commercially in both the public and private sector. The North American Industry Classification System (NAICS), is for classifying industries. This system replaces the Standard Industry Classification (SIC) codes.
