What a SIC code is
- The Standard Industrial Classification sorts businesses into 4-digit industries inside 2-digit major groups. The version used here is the 1987 edition, 1,004 industries.
- The US government replaced it with NAICS in the late 1990s, but company databases, directories and some mailing list sellers still sort by SIC.
- The two do not line up one to one. The crosswalk is the Census Bureau's own and it is the 2002 NAICS edition, the last one Census published against SIC; each NAICS code shown is checked against the 2022 list.
- Three-digit numbers are read with a leading zero, so 782 finds SIC 0782.
