How often can we change facebook phone number?

[tonychuan]

Hi,
I have been creating multiples facebook accounts recently. What I did to pass the mobile phone verification is to use my previous mobile phone number that I've used in old accounts and it proved to work.
But i wanna ask how often that i can use the same number to recreate another fb acc without getting ban on the previous acc that using that number.

Hope someone would know the answer.
thank you

I have worked out its around 3 months!

so it means we can use a same mobile phone number to create a new fb acc every 3 months and the old acc wont get ban, right?

I used same number for 3 accounts and they are still safe until now. I don't remember how to do so but it seems not very important to verify fb with different phone #

I use the same numbers over and over again. Add the number then wait a couple of days and then delete it. After a few days you can use it again. Numbers can be used on2 accounts too.
