How to block a phone number off an iphone 4 from verizon.please fast?

Can I do. It on my phone?

You have to call Verizon

I believe the number is 611

I kept getting texts that said vzwbnb: 1, I got 15 of them with in 3 days so I called them wondering what it was about, it was spam, he blocked it, but it takes 24 hours for it to kick in. After I hung up with him I got 3 more I would guess and have not gotten anymore from that number recently. Also the nber showed up as 62541 or something like that but when the Verizon guy looked it up they were coming from a number that goes something similar to this 000-004-8474 and then there was another number it was coming from also but it started with 4 zeros and not 5
