Gilbert Data offers products and services to deliver NAICS and SIC codes for your business records, to enhance your client’s relationship, scenarios, and businesses. NAICS, or The North American Industry Classification System, is used to catalog and to measure businesses in the United States, Canada, and Mexico. It is often used in combination with or instead of the Standard Industrial Classification (SIC) system.

Both are economy-based codes used to determine what kind of industry into which a business can be characterized. NAICS switched SIC codes for the most parts due to surplus technology-based classification, the market trends lifted as required and the Internet grew up, but many companies find SIC codes more important for their needs.
