Yahoo! Contacts is an online contact manager that helps you organize and communicate with the people in your life. It’s similar to a paper or desktop address book but has lots more features and functions. Use it to store all your contact information about individuals and companies. Because the contacts list is online, you can access it with an Internet connection from anywhere in the world.
Yahoo! Mail, Yahoo! Messenger, Yahoo! Toolbar, and Yahoo! Greetings all use the contact information in your Contacts list, so you can access your contact information from any of these applications.
