Taiwan’s statutory company register (公司登記) — every incorporated company, its 統一編號, registered name, responsible person, capital, registered address and current legal standing — from the Ministry of Economic Affairs’ Department of Commerce open-data service.

Tools

• twcompany_search_name(name, status?, limit?, offset?) — search the register by company name (Chinese or partial).
• twcompany_by_ban(ban) — the full registration record for one 8-digit 統一編號 (Business Administration Number).
• twcompany_status(ban) — normalized legal standing (registered / suspended / dissolved-or-revoked) with every register date converted from Minguo era.

Auth

Keyless. No registration, no key, no published quota.

Relationship to the other Taiwan packs

taiwan-procurement reads the public-tender bulletin (who won which government contract) and taiwan-stocks reads TWSE/TPEx market data for the ~1,800 listed issuers. This pack is the corporate register underneath both: it resolves a 統一編號 that appears in a tender award, and it covers the overwhelming majority of Taiwanese companies, which are not listed anywhere.

Data sources

• https://data.gcis.nat.gov.tw/od/data/api/5F64D864-61CB-4D0D-8AD9-492047CC1EA6 — 公司登記基本資料 by 統一編號. Full record: capital, paid-in capital, par value, equity, address, registering authority, setup/amendment/revocation dates, suspension window.
• https://data.gcis.nat.gov.tw/od/data/api/6BBA2268-1367-4B42-9CCA-BC17499EBE8C — 公司登記基本資料 by 公司名稱. Name search only.

Traps, all verified live 2026-09-17

Every one of these is a silent zero — HTTP 200 with an empty body — which is the failure class nothing pages you about.

• The name search REQUIRES a status filter. $filter=Company_Name like 台積電 alone returns HTTP 200 and zero bytes. Only Company_Name like X and Company_Status eq NN returns rows. No error, no hint.
• Only three status codes exist: 01 核准設立 (registered/active), 04 解散 (dissolved), 05 撤銷 (revoked). 02, 03, 06–09 all answer with an empty body, indistinguishable from “no such company”.
• The two datasets are not interchangeable. Each answers the other’s query with an empty 200: 6BBA2268 ignores Business_Accounting_NO, 5F64D864 returns nothing for a Company_Name like filter.
• The BAN dataset omits Company_Status and returns only Company_Status_Desc, so any code-based mapping silently loses the status on exactly the lookup most callers use.
• An unknown dataset id answers HTTP 200 with Chinese prose — 「此API不存在，請查明後繼續。」 — not a 404 and not JSON.
• Dates are Minguo (ROC) era, zero-padded YYYMMDD. 0760221 is 1987-02-21 (076 + 1911); 1150821 is 2026-08-21. Read as a Gregorian integer it is off by 1,911 years and looks entirely plausible. Both forms are returned.
• Capital_Stock_Amount is authorised capital, Paid_In_Capital_Amount is what was actually paid in. For large issuers they differ by billions of TWD.
