Can't enter confirmation code

I have to enter a confirmation code that is being sent to my old phone number. This problem has already been solved but I can't find where the solution is in this forum. The same question was asked by the user "Foton"

Ok so I clicked on the first link you provided but I get confused when I saw
"Moved from Facebook Support other problems to the Disabled account Mobile verification section "

I can't find the answer any where. I'm not to good with navigating through forums

I clicked the 2nd link and again I see
"Moved from Facebook Support other problems to the Disabled account Mobile verification section"

I get lost again but I scrolled down through the answers and I see this answer:

I read this page and if I understand correctly, I need to email facebook at this email address: privacy+7752ay@support[dot]facebook
Is this correct or not?

Also, I did see someone saying they just made a new facebook account and then they supposedly change their account settings to take different ways of confirming their identity and now he can log back into his old account???
