Taiwan — GCIS (商工登記) Lookup

Live, direct-to-government access to 經濟部商工登記公示資料 (Ministry of Economic Affairs, Department of Commerce) — GCIS open data.

Single-country variant of the cross-border Cross-Border UBO Chain Walker. Use this skill when the user is explicitly focused on Taiwan.

What you get

• Direct query to GCIS (商工登記). Every tool call hits 經濟部商工登記公示資料 (Ministry of Economic Affairs, Department of Commerce) — GCIS open data at the moment you ask. No nightly scrape, no aggregator middle layer.
• Unmodified responses. Field names, status codes, and (where available) raw filing bytes are returned exactly as the registry's own system emits them.
• Native ID format support. 8-digit Taiwanese 統一編號 / Unified Business Number (e.g. 22099131 TSMC).
• Sample entity: Taiwan Semiconductor Manufacturing Co Ltd (台積電).

Quirks specific to Taiwan

• Taiwanese 統一編號 (8-digit BAN) is the universal identifier — same number across business, tax, customs registers.
• Officer data covers 負責人 (responsible person), 董事長 (chair), 董事 (directors).
• Names are returned in Traditional Chinese; English names exist for listed firms but not all SMEs.
• Listed companies disclose more (TWSE / TPEx); private companies have minimal data.
