As per title, I am looking for a legit site that I can get a Portuguese NIF (Tax Identification Number) online. I have seen this one, but i don’t believe it to be legit, and the TrustPilot reviews aren’t great either.

Does anyone know of any legit ones?

EDIT - I have found a legit site, but it seems a bit ‘American’ to me… The reviews are great, but they charge in US$ and this thread makes it seems something I wouldn’t want. Although one reply says that they all do that etc. I’m starting to think that getting one online mightn’t be worth it for the hassle.
