You know not to give out your social security number. You know not to give out your passwords. You know not to give out your credit card information unless you contacted the person first.
But verification codes? Perhaps not so much. The same rules apply, however, to verification codes as to any sort of sensitive information. Treat it like a password. Don’t give it out to anyone. That means no one. Just don’t!
Multiple scams are being perpetrated on people, and the keys to the kingdom are given to the scammers simply by providing a verification code. With your cell phone number and a verification code, scammers can log into Zelle and steal your money. They can get a Google Voice phone in your name and intercept your verification codes to your bank accounts. So–if someone you don’t know calls you stating they need a verification code from you, no matter what they’re telling you the reason is, hang up. If they say an account of yours has been hacked, then either log into the website of that account or call the phone number you know to be associated with that account. Never call back a number an unknown caller gives you, because the truth of the matter is that someone calling you can say they’re anyone, and you really don’t know that to be the case.
