> To be able to pay with Pix, one needs to get a CPF (Brazilian Tax ID).

There are third party apps you can use to pay with pix using a credit card, can't recall that name, but read about it here a few months back, on another pix-thread.

> CPF (Brazilian Tax ID). Then to open a bank account

Getting a CPF is absolutely trivial, but I'm not sure you can open a bank account without RN/RNE, at least not with local banks. Can probably manage with one of the online banks.

For comparison, one does not need need to get US tax ID number to use a Visa card.

Calling a CPF a "tax ID" is a bit misleading, much like calling an SSN "the way you get social security benefits". You can (even as a non-citizen) get one in a couple mins at the post office, and it's used for literally everything, including things like buying a SIM card or registering for some public WiFi hotspots.

Okay, that's quite a bit less bureaucratic than American EIN, ITIN, or SSN (collectively known as TINs).

How many digits/letters long is it? One problem with American TINs is the entire space is only a billion digits, so it's not possible to assign one to every person in the world. If we could add two more digits or make 3 alphanumeric, it would be a lot more feasible to do this, but that is basically impossible at this point.

nnn.nnn.nnn-nn

A CPF is nationally unique.

You also have a RG/RNE which is unique per state. Not too often you get asked for this one though.

I think you need a RN/RNM to open a bank account even with online banks - I haven’t tried all of them of course so there might be some that work with cpf only
