Why am I being asked to add my mobile phone number to my account?
Adding a mobile phone number to your account:
  • Helps keep your account secure
  • Makes it easier to connect with friends and family on Facebook
  • Makes it easier to regain access to your account if you have trouble logging in
You may see a number suggested for you when we ask you to add your mobile phone number. It will only be added to your account if you choose to add and confirm it.
A suggested mobile number may be based on:
  • Your mobile phone or tablet
  • Your mobile operator
  • Contact info provided by others on Facebook
  • A mobile number that you entered previously but didn't confirm
Keep in mind that you can control who can see your phone number. Learn more in our Data Policy.
