It is my pleasure to assist you in updating your account. May I ask what is the reason for wanting to have a number blocked? We have to options for you. The best solution for you will be based on whether you would like the block to be permanent or temporary. Also, would you like the option to call or text the blocked number? This is a one-way block in which you can call the blocked number but the blocked number is unable to contact you. I have posted a couple of links for your review so you can decide which option suit your needs.
Once you have reviewed and select the option that works best for you then simply login to My Verizon to setup the blocks. If you have any questions or concerns on how to setup the blocks then simply reply to this message so I can further assist.
