SIC Industry Lookup Tool

Below is a SIC code lookup tool for United States publicly traded securities. This tool shows companies classified by Standard Industrial Classification codes, allowing you to find related peer companies, analyze industry structures, and generate investment ideas.

This tool is part of our public company industry classification suite. Please let me know about issues on our Contact Form.

Note: The database contains publicly traded securities that file with the SEC. Classifications are taken from SEC EDGAR.

This lookup tool allows you to browse companies by searching by SIC classifications:

For each company, you can also click the buttons to see detailed industry information or use the link to visit SEC filings directly.

Limitations to Consider

SIC codes offer valuable classification information, and I get them from SEC’s EDGAR. Still, you need to be aware of some limitations. I touched on them in the company SIC and NAICS lookup tool, but here’s a summary:

• The SIC system was last updated in 1987. Even at the time it was having a hard time keeping up with modern industrial development, so may not accurately reflect modern industries. That goes particularly for technology. (Try code 7389 for a funny example!).
• Companies self-report their SIC codes.
• Complex companies with diverse operations are limited to a single SIC code in SEC filings.

I use the SIC codes to populate NAICS codes for each company. They don’t map 1:1 in my database, so the NAICS codes can also be funny. But for a more comprehensive view, consider using both this SIC industry lookup tool and our NAICS industry lookup tool in your research.

SIC Code structure

The current tool only allows you to search by 4 digit SIC codes, without aggregating. I’ll look into how best to add 2 and 3 digit searches to the tool (or feel free to get in touch with ideas).

SIC codes use a four-digit hierarchical structure:

• First two digits: Major Group (Division or Sector)
• First three digits: Business or Industry Group
• All four digits: Specific Industry, or Specialization

For example, SIC code 7372 breaks down as:

• 73: Business Services
• 737: Computer and Data Processing Services
• 7372: Prepackaged software

Sources

The key for these company classifications is their self-filed SIC. Here is how I populate the data:

• SEC EDGAR: Primary source for company SIC codes and basic information.
• NAICS Association: NAICS-SIC code crosswalks and NAICS descriptions come from the NAICS Association.
