Body: <p>Our priority is Name Surname and <strong>Phone Number</strong> while we are creating a <strong>New Individual</strong> Entry 
  However when the same info is written, the system doesn't give a warning, which causes to create new accounts with the existed info beforehand.
  to solve this problem i have examined this essay below but i haven't got the desired results.

  <p>What i want is that the system shall not let me to create New Individual Entry if there is this phone number in somebody's profile already.</p>
  
  <p>Could you please launch a "<strong>Matching Rule for Individual Contacts</strong>" to this.</p>

  Go to Contacts > Find and Merge Duplicate Contacts > Add Rule for Individuals and create a 'Supervised' rule - eg:
  [![Name & Phone dedupe rule](https://i.sstatic.net/Hl5EW.png)](https://i.sstatic.net/Hl5EW.png)
  
  This probably only works for 'primary' phones rather than checking against all phones of a contact, but unless you have multiple phone numbers per contact, it should do what you need.
