A Google Voice verification code is a code sent via text message by Google when you sign up for Google Voice or add a phone to your account. You enter this code to activate Voice on your phone. Scammers may try to obtain this code from you by posing as a buyer or seller on online marketplaces, or by pretending to be a good Samaritan who found your lost pet or a long-lost family member. If you give them the verification code, they can use it to create a Google Voice number linked to your phone number, which they can use to rip off other people and conceal their identity. They may also use the information they obtain to access your accounts or open new accounts in your name. Therefore, it is important not to share your verification code with anyone and to report any suspicious activity to the appropriate authorities.
