Taiwan Company Lookup - 統一編號 GCIS Registry Search

What is Taiwan Company Lookup - 統一編號 GCIS Registry Search?

This Actor is a Taiwan company lookup and 統一編號查詢 / 公司登記查詢 tool built on the official GCIS open data API (經濟部商工行政資料開放平臺) of Taiwan's Ministry of Economic Affairs (MOEA, 經濟部). Look up companies by Unified Business Number (統一編號, tax ID / UBN), search by company name keyword (公司名稱), or pull newly established companies (新設立公司) by date and city. You get the official Chinese name, status, authorized and paid-in capital, representative (代表人), address, registration authority, incorporation and last-change dates, plus directors and supervisors (董監事), business items (營業項目) and optional branch offices (分公司). Export as JSON, CSV or Excel or use the Apify API.

• ✅ Official government source: MOEA company registration (公司登記) and business registration (商業登記) data.
• ✅ No API key, no captcha, no proxy: uses the public GCIS API, not the findbiz.nat.gov.tw website.
• ✅ Bulk 統一編號 check: paste hundreds of tax IDs; the check digit is validated before querying.
• ✅ Board and shareholding: directors, supervisors, represented juristic persons and shares held.
• ✅ Lead lists: new companies established in the last N days, filtered by city (臺北市, 新竹, 臺中市 …).
• ✅ Cheap and predictable: $1.50 per 1,000 results, platform usage included.

Invalid or unknown numbers produce an item with "ok": false and an error: invalid_tax_id_checksum, invalid_tax_id_format, branch_office (the number belongs to a 分公司) or not_found. If GCIS does not answer after several retries (api_error), that number is not written to the dataset and not charged; it is listed in the run summary instead (see below).

How much does Taiwan company data cost?

This Actor uses pay-per-result pricing: $1.50 per 1,000 results ($0.0015 per company), with Apify platform usage already included. Apify also charges a tiny Actor start fee of $0.00005 per run per GB of memory.

• What counts as a result? Every dataset item: one per company found, plus one per invalid / not-found tax ID.
• Temporary failures are not charged. If GCIS is temporarily unavailable (network errors, timeouts, HTTP 5xx, quota messages), the affected tax IDs are not written to the dataset and nothing is charged for them. They are listed under failedLookups in the run summary (key-value store record OUTPUT, linked as Run summary in the run's Output tab) so you can run them again later. After 3 such failures in a row the run stops; if nothing billable was found, it is marked as failed.
• Directors, business items and branches are included: they are nested in the company record (they only make the run slower).
• Control your spend with maxItems (default 100).
• How much fits in one run? At the defaults a run outputs at most 100 records; extra tax IDs are skipped with a warning. Raise maxItems (up to 10,000) for bigger jobs. Each company takes about 1–3 s with directors and business items on, so one run with the default 30-minute timeout handles roughly 500–1,000 companies. For more, turn off the extra details, raise the run timeout, or split the list into several runs.
• Examples: 1,000 companies ≈ $1.50. The default input (3 companies) ≈ $0.005.
• Free plan: Apify's free plan includes $5 of monthly usage, which covers about 3,000 companies.

Use the Taiwan company API from Python, JavaScript or no-code tools

Python (apify-client):

from apify_client import ApifyClient

client = ApifyClient("<YOUR_APIFY_TOKEN>")
run = client.actor("1rrock/taiwan-company-lookup").call(
    run_input={"taxIds": ["22099131", "04541302", "84149961"]}
)
for item in client.dataset(run["defaultDatasetId"]).iterate_items():
    print(item.get("taxId"), item.get("name"), item.get("status"), item.get("capitalPaidIn"))

JavaScript / Node.js (apify-client):

import { ApifyClient } from 'apify-client';

const client = new ApifyClient({ token: '<YOUR_APIFY_TOKEN>' });
const run = await client.actor('1rrock/taiwan-company-lookup').call({
    companyName: '半導體', cities: ['新竹'], maxItems: 50,
});
const { items } = await client.dataset(run.defaultDatasetId).listItems();
console.log(items.map((i) => [i.taxId, i.name, i.representative]));

HTTP (one call, returns the results):

curl -X POST "https://api.apify.com/v2/acts/1rrock~taiwan-company-lookup/run-sync-get-dataset-items?token=<YOUR_APIFY_TOKEN>" \
  -H "Content-Type: application/json" \
  -d '{"taxIds": ["22099131"]}'

No-code: connect the Actor to Zapier, Make, Google Sheets (with Google Sheets Import & Export), webhooks and other integrations. Run it on a schedule for a daily new-companies feed, or let AI agents call it through the Apify MCP server.

FAQ

Is it legal to use GCIS company data commercially? 可以商業使用嗎？

Yes. GCIS publishes the data under the 政府資料開放授權條款－第1版 (Open Government Data License, version 1.0), which allows any use, including commercial, without a fee, and is compatible with CC BY 4.0. You must keep the attribution statement (顯名聲明); every record carries it in attribution.

How is the 統一編號 check digit validated?

Weights 1-2-1-2-1-2-4-1 are applied, the digits of each product are summed, and the total must be divisible by 5 (the Ministry of Finance rule since 2023, compatible with older numbers). If the 7th digit is 7, the special case is handled. Invalid numbers are reported without calling the API.

Does it include sole proprietorships (商業登記)?

Yes, for tax ID lookups: if a number is not a company, the Actor checks the business registry (獨資、合夥) and returns name, status, organization type, address, authority and business items. Name search and new-company lists cover companies (公司) only.

How fresh is the data?

Results come live from the GCIS API, which follows MOEA's registry updates (new incorporations appear the same or next day).

What are the limits?

• The name keyword must match the Chinese registered name; English names are not part of the open API.
• Name search returns active companies by default; set status to all to include dissolved ones.
• Name searches and new-company lists fetch details per company, so they take about 1–3 s per company with directors and business items on (roughly 500–1,000 companies within the default 30-minute timeout). Turn off the extra details or raise the run timeout for bigger jobs.
• Financial statements and shareholder registers are not part of the open data.

Fair use

The Actor calls the GCIS API sequentially with a polite delay and backs off on errors or quota messages. Please keep runs reasonable; GCIS applies daily usage limits.
