People can look you up on Facebook using your phone number. Here’s how to stop them.


Written by:

If you’ve ever given your phone number to Facebook, anyone can find your profile by running a Facebook search on that number. And we mean anyone with a Facebook account—not just your friends. Recently, a security researcher demonstrated that he could exploit Facebook by connecting hundreds of thousands of phone numbers with their owners’ names.

Even though Facebook lets anyone find you through a reverse phone number lookup by default, you can prevent it from happening by following these simple steps: 

Step 1: Log into your Facebook account.

Step 2: Go to Privacy Settings.

Step 3: On the Privacy Settings page, you’ll see a section for “How You Connect.” Click “edit settings” next to it.

Step 4: A box titled “How You Connect” will open. On the drop-down menu next to “Who can look you up using the email address or phone number you provided,” select “friends.” (This is as private as you can go; Facebook won’t let you limit it to “no one”).

Step 5:  Click the “Done” button to save your changes.

You’re done! Now you’ve limited Facebook’s reverse phone lookup so that only your friends can find you through your number. Unless it’s absolutely necessary, it’s a good idea to avoid giving your phone number to any social network, despite them repeatedly asking for it for “security purposes.”

    Muito interessante ter este tipo de informação, ficar na rede desprotegido é uma furada!! Obrigados a todos que valorizam a privacidade. O mundo é capitalista e já pagamos alto de mais por isso.

  5. This is STILL the case. The settings for email and phone number appear to have been split up now, but I just checked mine and the phone number lookup was set to “Everyone”.
    Here’s the link to the settings page:

    I originally reported this to Facebook in May 2012 (as I think reverse phone searches are illegal in the UK) but they ignored it. This was the result:-

    FYI: There are also search engines like The Email Archive and The Phone Archive that let you lookup where an email address or phone number has been used in documents, webpages etc

    Excellent post, but I just discovered something about this Facebook Privacy function, each time you uninstall the app from your iPhone and install it again, whatever reason could be (safe some space for the hard disk), this function changes automatically and turns on into “Everyone”, so if you change this but after a while you discover is again on “Everyone” mode is because you probably installed again the Facebook app on your iPhone.

    Hope it can help!
