Get rid of call back number at bottom of texts?

Well I have verizon, but it doesnt show the CB number. What I did was I went to the Messaging tab on my phone and went to Settings (I dont know how to get there with your phone, but you probablly do,) then near the bottom of the list theres a thing that says " *. Callback #" click on that and it should give you the option of turning it off or on.
