You’ve got four ways to view contacts: view your entire contacts list, view a single contact’s details, sort your list to view it differently, or search for a contact.
Contacts list
Click Contacts in the list down the left side of your Yahoo! Mail page. Your contacts list opens in Yahoo! Mail's main window. See it?
Contact details
View a contact’s details by clicking on their name. Details appear in the area to the right – Name, phone number, address. Whatever you’ve entered, there it is. To edit this information, click Edit. The last line on this side – “Last updated” – tells you when you most recently made changes.
Sort contacts
Sort your list of contacts in ascending or descending alphabetical order – your choice! – by clicking the small black triangle on the right of the “Name” bar above your list of contacts. And you can list names first-name-first or last-name-first by clicking on the circling arrows icon next to the word “Name”. Click it again to switch back. Carlos Santana. Santana, Carlos. Carlos Santana. Santana, Carlos!
Search contacts
To search for a contact, simply begin typing the contact’s name or email address in the Find Contacts box above the list of your contacts. AutoComplete will recognize matching contacts after only a few letters. When you see the right name or address appear below, click on it to open contact details on the right.
