Blocking Calls on Verizon Wireless

Even though my mobile phone number is on the "do not call" list, I still get an occasional strange call on my Verizon Wireless smartphone. When I go to answer the call, it hangs up. It must be some type of automated prank (or crank) call.

To fix this problem, I've been using the online "My Verizon" portal to block these annoying calls. So far, I've blocked these numbers:

• 201-244-7067
• 559-457-0453

Verizon will only let you block up to 5 numbers and I hope I don't max out anytime soon.
