Adding your phone number to your account will help keep
your account secure, make it easier for you to connect with friends and
family on Facebook and make it easier to regain access to your account
if you have trouble logging in.
When we ask you to
add your phone number, you may see your number automatically suggested
so that it's easier for you to add. This might be based on your phone or
tablet, your mobile operator, contact information provided by others on
Facebook, or other sources. We also might have your number because you
gave it to us in the past, but haven't confirmed it. The number will
only be added to your account if you choose to confirm and verify it.
Note: You can control who can see your number on your profile.
