Use the Contacts Profile page to designate the main contact information for a person or company.
Contacts can have several mailing, email, and Internet addresses, as well as several phone and fax numbers. Typically, the item that you add first in a section is set as the primary, so if you have multiple addresses and numbers, it is important that you designate which information is the main information.
The primary items in each section are marked with a check mark in a circle, and this information is what is displayed on both the list view and card view.
You can change the designated primary entry at any time.
