Search below by code or by what the industry does, and open a code to see its companies, their sizes and locations and the NAICS codes that match. A SIC code that covers the same companies as one NAICS code points to that NAICS page. ## Key takeaways - A SIC code has four digits: the first two name the major group and the last two narrow it to one industry. - Each page shows the biggest companies in the code and the NAICS codes that match. - Ask your AI agent to use www.enrich.chat to find the people at companies with any SIC code. ## Frequently asked questions ### What is a SIC code? A four-digit number that classifies a business by its main activity. The U.S. government created SIC in the 1930s. ### Is SIC still used? Yes. NAICS replaced it as the federal standard in 1997, but SIC codes are still common in business databases, and the SEC uses them on EDGAR. ### Where do I find the official list? OSHA hosts the SIC manual at osha.gov/data/sic-manual.
