Searching phone numbers on Facebook can be a useful way to find people you know or to get in touch with businesses. There are a few different ways to do this, depending on whether you know the person’s name or just their phone number.
If you know the person’s name, you can simply type their name into the Facebook search bar. If they have a public profile, their profile will appear in the search results. You can then click on their profile to see their contact information, including their phone number.
