Taiwan Company Lookup by Unified Business Number (統一編號): Name, Status, Capital, Address

twgcis/company-by-tax-id

Look up a Taiwanese company by its eight-digit unified business number (統一編號, also the tax id) in the Ministry of Economic Affairs company register: registered name, status (for example 核准設立, approved), authorised and paid-in capital in NT dollars, responsible person, registered address, registering authority, setup date and date of the last approved change. Dates are seven-digit Republic of China (Minguo) dates: add 1911 to the first three digits. A number that is not registered returns a provider error. Returned as a list under results.
