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.
