I have my contact number in my About section and the Facebook search engine returns just my profile, so you know that's the best one.
Find Facebook By Phone Number
But here's a search I did by phone number for someone I'm not linked to and who doesn't have their contact number in their public profile. (Sorry for the blurring-- to secure the innocent victim of my research study.).
How to Conceal Contact Information on Facebook.
1. As soon as once again go to your account, click on the [Accounts] tab and select Privacy Settings link.
2. On the Personal privacy Settings page, scroll down and click on Customize settings link (see photo. above).
3. On the Customize settings page scroll down to discover Contact information section and it will reveal you all the contact info and whom you enable to see it.
4. Click on any among the contact information. like mobile number and choose the type of individuals who can see/access it. If you want to hide your contact number on facebook entirely from everybody choose Customize. (see above).
5. In the next window under Make this noticeable to you can select the alternative Only Me or the others.
Find Facebook By Phone Number, By choosing "Only Me" youre defining that only you can see that contact info on your facebook profile, while the remainder of the world will not see it at all or gain access to from their phone book page, unless you specify certain people in the above action to see them.
