2. Send certain calls straight to voicemail

You need to talk to a particular person, but you don’t want them to have your real number. When you don’t want to block someone outright, you can send them to voicemail. You can do the same for all incoming calls with Google Voice. This is smart when you use that second number as a burner you really don’t intend to take calls on.

3. A safer way to give your contact info to strangers

When asked for your phone number by a new social or business acquaintance, you give it. Perhaps it’s on your business card. The same happens when you sign up for a new account or want to sell something online. Just one bad actor can get a hold of your number and make your life miserable. Spam and robocalls can come through phone calls or texts. A hacker can use your phone number to get into one of your accounts and access your information. A burner phone number minimizes your risk. This step is simple. Instead of giving out your real number, pass along your Google Voice number.
