DESCRIPTION

NAICS is a hierarchical industry classification jointly developed by the U.S., Canada, and Mexico. It replaces the older SIC system and supports collection, analysis, and publication of economic statistics. NAICS codes enable segmentation, benchmarking, and linkage of company records across datasets. Codes are periodically revised to reflect structural changes in the economy, such as digital services. Organizations use NAICS in master data, KYC, and market analysis workflows. It is widely referenced by government surveys, procurement, and commercial databases.
