this number 720-358-4152 called my mother's cell twice. Once said," your verification number is and it gives her a number". They called an hour later and said the same thing giving her a (different) verification number. I looked up the number and it's out of  Hudson Co. A landline and it's carrier is Level 3 communications. If it keeps on I will investigate further.

7203584152 me too this number try to call me 7 times but I didn't unswer it. And I got two messages from 99999 and 607941 with WhatsApp code.
All I know that someone there trying to transfer my WhatsApp meassages and groups to him too or something like that.

My location is in Indonesia.i dun know where they got my cell phone no.called me 3times.at first i picked up n there is like an auto operator talking english then i hang up cos i was worry that i may get pay the international call roaming.n then after 2days call me again but i didnt pick up anymore.i think must be those scammers.

Same, my mother has received calls from this number with a "verification code" outisde the US. I have called to this number and there is no answer. This should be investigated, it's agains the rights of the citizens be disturbed by these kind of phone calls.

Same here got called like 4 times, got also a whatsapp code.. Strange!!!
