Hello Allie02151978! Great question!! There is such an option through Usage Controls. You can add the feature, which would then allow you to set restrictions against the specific number from both calling and being called by phone of your lines. It's a great feature, but you do want to also keep in mind that it won't prevent the person from finding a different phone to call your line. You kind find out more about Usage Controls at verizonwireless.com.
