**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.

**How many companies do you cover?**
