NAICS Lookup FAQs

What is a NAICS code?

NAICS (North American Industry Classification System) is a 6-digit code that classifies businesses by their primary industry. It's the standard used by U.S., Canadian, and Mexican government agencies to collect and publish statistical data about the economy.

How do you determine a company's NAICS code?

We analyze a company's website, business description, products, and services to determine the most relevant NAICS codes. Our enrichment engine cross-references multiple data sources to ensure accuracy.

Can a company have multiple NAICS codes?

Yes. Many companies operate across multiple industries and can have more than one NAICS code. Our tool returns all relevant codes for a given company, not just the primary one.

Is this tool really free?

Yes, the NAICS lookup tool is completely free to use. No signup, no API key, and no credit card required. For bulk lookups or API access, check out our Company Enrichment API.

What's the difference between NAICS and SIC codes?

NAICS replaced the older SIC (Standard Industrial Classification) system in 1997. NAICS is more detailed, covers modern industries like tech and e-commerce, and is updated every 5 years. SIC codes are still used by some agencies like the SEC.

How many companies do you cover?
