If they dont put *67 in front of your number, you would see their number.
If someone has blocked your number, using our Call & Message block feature, they are not notified of your phone calls or text messages. The only one notified is the caller which they hear a message stating "Welcome to Verizon Wireless. We're sorry, the number you have dialed has calling restrictions that have prevented the completion of your call." If the blocked number tries texting, it will simply not go through.
I hope this answers your question.
