NAICS 2022 — Complete
The full U.S. Census NAICS 2022 taxonomy in two files: the complete file with the official Census descriptions joined in (rare — most free copies split codes and descriptions across sources), plus a lightweight codes-only file.
| File | Rows | Columns |
|---|---|---|
naics-2022-full.csv | 2,125 | code, title, level, level_name, description |
naics-2022-codes.csv | 2,125 | code, title, level, level_name |
SIC 1987 + SIC↔NAICS Crosswalk
The legacy SIC 1987 list (enriched with major group and division) plus the official Census SIC↔NAICS concordance with both the SIC and NAICS titles already joined — ready to VLOOKUP or merge into a data pipeline.
| File | Rows | Columns |
|---|---|---|
sic-1987-codes.csv | 1,005 | code, title, major_group, division_code, division_name |
sic-to-naics-crosswalk.csv | 2,163 | sic_code, sic_title, naics_code, naics_title |
HS Codes (Harmonized System)
Harmonized System customs headings from the public-domain U.S. HTS — chapters, headings and subheadings with a level column, ready for product classification and catalog tagging.
| File | Rows | Columns |
|---|---|---|
hs-codes.csv | 6,840 | code, title, digits, level |
Complete Bundle — everything
All five CSV files (NAICS full + codes, SIC 1987, SIC↔NAICS crosswalk, HS codes) in one download — the best value if you work across systems.

What you get — and the fine print
Format
UTF-8 CSV, one file per dataset, opens directly in Excel, Google Sheets, LibreOffice, or pandas/R. Every file is de-duplicated and dated.
Sources & freshness
Compiled from public-domain U.S. government data (U.S. Census NAICS 2022 & SIC, U.S. Census SIC↔NAICS concordance, U.S. HTS). Each download is dated and states its source revision. Codes are revised periodically by the issuing agencies; we do not sell a stale file labelled as newer than it is.
Licence
Single-organisation use inside your own products, apps, spreadsheets and pipelines — commercial use allowed. You may not resell or redistribute the files as a standalone competing dataset. Full terms ship in LICENSE.txt with every download.
Need live checks instead of a static file?
If you need to validate or classify on the fly, use the CodeClassify JSON API (search NAICS/SIC/HS, run the crosswalk, validate barcodes/IBAN/VAT and more) — up to 100 items per call, free tier included.
Datasets are cleaned compilations of public-domain reference data, provided as-is for reference — not official determinations or legal advice.
