Who called from 2023305188

requesting non-aliens to fax their personal and bank info to this number, by letter sent on IRS letterhead (claims to be IRS form W-BE8N).

I've got a fax in Brazil from this number with a message pretending to be from the US IRS, requesting me for "recertification of foreign status". The issue is that I'm Brazilian, living in Brazil with no business in the US. I didn't answer it because it seems to be a fraud.
