From this number I get a call

Rcvd vm from this #, said "your verification code is ------, your verification code is------".
At the same time, rcvd text from different number 647-927-5516 "WhatsApp code ------"

Haven't been trying to verify anything, have no clue what WhatsApp is, was asleep at the time.

I got calls from that number too. And I don't live in USA. I live in Europe...

Stupidly answered the phone. A recorded message in a non English nor Spanish nor German nor French or Russian or Chinese or Japanese language started. Callerid says Unknown Name.

This is a legit call - this is from whatsapp - a free wifi text/call app company. when you open an account or change phones they send you an authorization # or verification # so you can activate the app and it's a recording.
