This will make keeping your social media private during recruiting much much harder because rather than trying to search for your name on FB or your email, an interviewer can just search your listed contact number. Names are often not unique but phone numbers are.
This matters because creating a new email account for recruiting is trivial, yet creating a new phone number for recruiting is not. Most phones are not dual sim, and you want to have a phone on you in case the recruiter or future employer calls. Hence the account id rate using a phone number should be much higher and makes it dramatically easier to find somebody.
The nasty part is even if you rename your account to your "first-name middle-name" or an alias, you could be found out via phone number search. So simply renaming your account no longer ensures random recruiters can't just find your profile. Your FB name could be "giant blue monkey" which prevents a regular name search but would still be identifiable via phone number search.
