Free All Industry Classification

A Standard Industrial Classification (SIC) code is a four-digit numerical code assigned by the U.S. government to classify businesses by their primary type of economic activity. SIC codes are used by the SEC to organize and categorize companies for regulatory and analytical purposes. For example, SIC code 6021 represents National Commercial Banks, while 3826 represents Laboratory Analytical Instruments.

A Central Index Key (CIK) is a unique identifier assigned by the SEC to every entity that files documents with the commission. CIK numbers are used to look up company filings in the SEC's EDGAR database. Each CIK is a 10-digit number (padded with leading zeros) that uniquely identifies a company, fund, or individual filer.

Industry classification data is essential for peer comparison, sector analysis, and portfolio diversification. By filtering companies by SIC code, you can identify all competitors within the same industry, compare financial metrics across peers, and ensure your portfolio is properly diversified across different sectors. Analysts and fund managers use SIC codes to build industry-specific benchmarks and track sector performance.

SIC (Standard Industrial Classification) codes are four-digit codes developed in the 1930s and still used by the SEC for classifying public companies. NAICS (North American Industry Classification System) codes are six-digit codes that replaced SIC for most government statistical purposes in 1997. While NAICS is more modern and detailed, the SEC continues to use SIC codes for company filings and regulatory classification.
