Social Media company Facebook had clarified that Facebook is NOT sharing the user’s phone contacts to the entire world.
Read below the Facebook updates of Facbook.
Rumors claiming that your phone contacts are visible to everyone on Facebook are false. Our Contacts list, formerly called Phonebook, has existed for a long time. The phone numbers listed there were either added by your friends themselves and made visible to you, or you have previously synced your phone contacts with Facebook. Just like on your phone, only you can see these numbers.
Facebook isn’t known for having the best privacy and security practices in the business. That’s why many users believed that Facebook had shared their contacts with anyone on Facebook.
