I am selling some stuff. I don't want to put my real number on the website so I installed an app on my phone which gives me a second number. I put that number on the site. a scammers texted me with the standard "I want to make sure you are real, I will send you a code, read it back to me" to try to verify google voice. I wanted to fuck with him so I said ok send it. surprisingly, the code came to the app. I thought google voice would say "this number cannot be used for verification" and not send the code. Now what I am wondering is, did I just discover an app that assigns legit numbers and not voip numbers? OR google voice sends the code without any checking, BUT THEN when you enter the code it will say this number cannot be used for verification?
