FAQ
Common questions
What is the unified business number?
The eight-digit identifier with a check digit that every Taiwanese company carries. It serves the register and the tax side together, and it is the number a profile call takes.
Can I search by name?
Yes. Names are matched fuzzily and the nearest candidates return ranked, each carrying its unified business number, status and address.
Is the search free?
It is free on this page with no account, and search is free on the API too, never billed on any plan.
