In various example embodiments, a system and method for contact merge management is provided. In example embodiments, a contact management system detects that a first contact list of a first user has a first contact including a first value and a second contact including a second value. The contact management system identifies that at least one further user is associated with a further contact list that has a third contact including the first value and the second value. Based on the identifying of the third contact including the first value and the second value, the contact management system causes an automatic merge of the first contact and the second contact in the first contact list into a single contact.
