Here's how it works. Scammers target people who post things for sale on sites like Craigslist or Facebook Marketplace.The personal phone number you submitted and linked is from a telephone carrier that is ineligible to be used to claim a Google Voice number. Fraudsters will sign their targets up for Google Voice to access their verification code and hijack the account and personal information. It involves scammers targeting people who post items for sale on websites like Craigslist or Facebook Marketplace. The scam where you tell them the verification code that gets sent to your number? Once a password reset link is sent via email it requires receiving a text message for verification. You're not a Google Voice user, but have been scammed to give your verification code. You don't want calls forwarded to you from Google Voice. To completely avoid a Google Voice verification scam, only do business in person with verified funds.
