NAICS & SIC Industry Classification Reference Data — Free Download

The North American Industry Classification System (NAICS) is the official standard used by the U.S. government to classify businesses for economic analysis, reporting, and regulatory purposes. Introduced in 1997 as the successor to the SIC system, NAICS has undergone multiple updates—most recently in 2022—to reflect the evolving structure of the economy.

As part of our complimentary Data-as-a-Service offering, we provide a fully curated reference package that includes:

• The latest NAICS 2022 codes
• The final SIC code set
• A clean, validated crosswalk between SIC and NAICS
• All files delivered in optimized Parquet format for fast ingestion and querying
• A Databricks-ready notebook with table definitions, schema details, and automated loading scripts

This package showcases how WestRidge Group’s data engineering workflows streamline complex reference datasets into analytics-ready assets—immediately usable in modern platforms such as Azure Databricks.

Use it freely as a high-quality sample of the reliability, structure, and performance you can expect from our broader data catalog. Let us help you accelerate your data foundation with clean, trusted, and consistently maintained reference data. This is also included all WRG Data Lakehouse offerings
