TIN Number (稅務識別碼) for Foreign Freelancers in Taiwan

[fifieldt]

It’s your ARC number.

The second point of that document says that if you have a 統一證號, it’s your TIN. An ARC number is a form of 統一證號.

Further down, there’s also a note that anyone without a 統一證號 can apply to the NIA for one. See eg this recent thread for information on that.

Registering on Ruten - Unified ID for Foreigners? Another way?

I want to buy a thing that’s unfortunately only on Ruten & Yahoo shopping. I go to register on Ruten and it says give your Taiwan ID, ARC, or Unified ID - none of which I have, and the first two I can’t get. So how do I get this mythical Unified ID, and is there a practical alternative for foreigners? Do they check? I have a local phone number they can verify with, just not sure about the ID requirement.
