How this service works
List the codes one level below a NAICS 2022 code (sector to national industry); omit the code to list the 20 sectors.
Output
Returns a list of child NAICS 2022 codes (one level below the requested code), each with its code string, title, numeric level, and level name. Also includes the parent code and title, total child count, the name of the child level, data source attribution, and an asOf timestamp.
Example use cases
Browse NAICS top-level sectors
“Show me all 20 top-level NAICS 2022 sectors so I can pick the right one for classifying a new business.”
Drill into a NAICS industry group
“What are the NAICS 2022 codes one level below industry group 5415 — I need to see all the sub-industries under Computer Systems Design.”
Build industry dropdown for onboarding
“I'm building a business registration form — can you fetch the direct children of NAICS sector 23 (Construction) so I can populate a dropdown of subsectors?”
Technical details
Endpoint
GEThttps://industry-occupation-codes.x402tookit.com/naics-children?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to traverse the NAICS 2022 hierarchy level by level — discovering what industries exist under a given sector, subsector, or industry group. Prefer it over a search endpoint when you know the parent code and want a complete, authoritative list of its direct children rather than a keyword-filtered result.
Side effects
- Invalid or malformed NAICS code returns an error or empty children list
- Code at the deepest level (national industry, 6 digits) has no children
- Code with wrong digit count may not match any NAICS level
- Network or payment failure returns no data
