  3. Make sure you press the Enter or Return key on your keyboard to initiate the search. You can enter the phone number like "(555)555-5555" or "5555555555," as the formatting does not matter.[3]
    • A single search result should appear. If you don't get a result, that person probably has their profile set to private and won't show up in search results. It's also possible they may not have a Facebook account connected to that phone number.
  4. That is the Facebook account associated with the phone number you entered.
