- When you link contacts, those contacts aren’t merged.
- If you link contacts that have different first or last names, the names on each individual contact card will remain the same. However, only one name will be displayed on the unified card. You have the option to select which name you want to appear on the unified card.
- Whenever you make modifications or additions to a unified contact, the changes will be automatically reflected in every source account where the same information already exists.
