How this service works
NAICS 2022 code to title, level (sector to national industry) and full parent chain. Census Bureau data.
Output
Returns the code, its human-readable title, numeric level (2=sector through 6=national industry), level name (e.g. 'subsector', 'industry group'), number of child codes, and an ordered parent chain array — each parent including its own code, title, level, and level name — plus attribution and data source metadata.
Example use cases
Enrich business profile with industry hierarchy
“I have a company record with NAICS code 4441 — can you look up its full title, level, and parent sector chain so I can tag it properly in our CRM?”
Validate and decode NAICS code on a government form
“We received a vendor application listing NAICS code 336411 — what does that code mean, what level is it, and what sector does it fall under?”
Build industry breadcrumb for a directory listing
“For our industry directory, I need the full hierarchy for NAICS 722513 — give me the title at each level from sector down to this code.”
Technical details
Endpoint
GEThttps://industry-occupation-codes.x402tookit.com/naics-lookup?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need authoritative NAICS 2022 code-to-title resolution with full hierarchical context (parent chain, level name) sourced directly from Census Bureau data. Prefer it over manual lookups or scraped data when you need structured, machine-readable hierarchy for enrichment, validation, or directory building. Use when you have a specific code and need to decode it — for keyword-based discovery, prefer the NAICS search endpoint instead.
Side effects
- Invalid or non-existent NAICS code returns a null result or error verdict
- Code outside the 2–6 digit range or malformed input returns a validation error
- Sector range codes (e.g. 31-33) may not resolve if format is not matched exactly
- Payment failure (402) if x402 micropayment is not completed
- Upstream Census Bureau data unavailable returns a degraded response flag
