FAQ

How do I find the equivalent NAICS code for a SIC code?

Enter your SIC code in the resolver above. The tool will suggest possible NAICS matches based on title similarity and known mappings.

Can one SIC map to multiple NAICS codes?

Yes. The SIC and NAICS systems have different structures, so a single SIC code may correspond to several NAICS codes. The resolver lists the most likely matches.
