BBB warns online sellers of verification scam

By Greg Collier

The Better Business Bureau is sounding the alarm to online sellers that they may not want to list their phone numbers in their ads. That’s because scammers will call these numbers posing as a buyer, only to try to use the seller’s phone number in another scam.

For those who may not know, Google Voice is a service offered by Google that allows you to have a second phone number. That second phone number can be used for a variety of purposes. Some users who have multiple phone numbers for work and home can have all their calls forwarded to their Google Voice number. Many others use it as a way to keep spammers away. For example, when a store you frequent always asks for your phone number, you can give them your Google Voice number instead. You can even use it to avoid taking any calls. If you set it to ‘Do Not Disturb’ anyone who calls that number will be sent straight to voicemail.

While Google Voice is a convenience for consumers, it’s also been a boon for scammers. Each Google Voice number needs to be attached to an actual phone number. You can’t sign up for the service without one. Scammers can’t use their actual phone number to sign up for Google Voice because then their calls will be traced back to them. So, what they do instead is try to sign up for Google Voice using a victim’s phone number.

If you’re selling something online and have posted your phone number in the listing, the scammer might act like they’re sending you a code to verify that you’re not a scammer. What’s really going on is they’re signing up for Google Voice using your phone number. It’s Google who is actually sending you the verification code. If a victim gives the verification to the scammer, the scammer can then use the Google Voice number that’s tied to the victim’s phone to make more scam phone calls. If another victim complains, the phone number is traced back to the initial victim instead of the scammer.

This scam is not just used for Google Voice. It can be used to hijack a number of online accounts, including financial accounts. If someone you don’t know says they’re sending you a code for verification, do not give them that code number. Also, you shouldn’t list your phone number in any ad listings you post. Most platforms, including Geebo.com, have a method of communicating with the seller or buyer without compromising your phone number.
