How this service works
Looks up a NAICS industry code and its parent hierarchy, or searches NAICS industry titles by text.
Output
Returns one or more NAICS industry records including the code, title, and parent hierarchy (sector, subsector, industry group, and industry level codes and titles), depending on whether the query was a code lookup or text search.
Example use cases
Business registration industry classification
“I'm registering a new business that does custom software development — what's the right NAICS code and what does its industry hierarchy look like?”
Search NAICS codes by keyword
“Search NAICS industry titles for anything related to 'healthcare' and give me the top 10 matches with their codes.”
Verify supplier industry classification
“I have a supplier that claims to be NAICS code 336111 — can you look that up and confirm what industry it covers and show me the parent codes?”

Endpoint
GEThttps://fittings.sh/v1/naics/lookupWhen to prefer
Use this endpoint when you need to look up or validate a specific NAICS code, retrieve its full industry hierarchy, or find NAICS codes matching a keyword or industry description. Prefer this over generic web searches when you need structured, authoritative NAICS classification data for business registration, regulatory filings, market research, or supplier classification.
Side effects
- Invalid or non-existent NAICS code returns no results or an error
- Text search with no matching titles returns an empty results list
- Limit parameter out of range (not 1-50) may return a validation error
- Ambiguous query with mode='auto' may incorrectly interpret a numeric string as a code rather than text
