How this service works

single-fact naics lookup. Complete for the bundled 2022 vintage: all 2129 NAICS 2022 codes at levels 2 through 6, titles verbatim from the Census workbook, with the three range-spelled sectors (31-33, 44-45, 48-49) expanded to one entry per member sector. NAICS is a closed set, so a well-formed code absent from this snapshot is absent from the 2022 vintage. Refresh is a redeploy, never a live fetch.

Output

Returns the verbatim Census Bureau title for the requested NAICS 2022 code, including its hierarchical level (2–6), and confirms whether the code exists in the 2022 vintage. Range-spelled sectors (31-33, 44-45, 48-49) are expanded to individual member sector entries.

Example use cases

Enrich company profile with industry label

“I have a list of companies with their NAICS codes — can you look up NAICS 541512 and tell me the official 2022 industry title so I can label our CRM records?”

Validate NAICS code for grant application

“We're filling out a federal grant application and need to confirm that NAICS code 336111 is a valid 2022 code and get its exact official title.”

Decode NAICS code from a business filing

“I pulled NAICS code 722513 off a business registration document — what does that code actually mean, like what industry is it?”

When to prefer

Choose this endpoint when you need a fast, authoritative, offline-safe lookup of any NAICS 2022 code title — especially when you need full coverage of all 2129 codes including the tricky range-spelled sectors (31-33, 44-45, 48-49). Prefer this over scraping the Census Bureau website or maintaining your own NAICS table, and when you need consistent, reproducible results tied to a specific vintage year.

Side effects

Code not found: well-formed code absent from 2022 vintage returns a not-found response indicating it is not part of the standard
Malformed code: non-numeric or out-of-range input returns a validation error
Data staleness: snapshot is pinned to 2022 vintage and will not reflect future NAICS revisions until a redeploy occurs
