First, make very sure that is what you want to do, if you delete the account you can never get it back, or use that ID name, either.

Any other yahoo programs associated with your mail account will also be deleted.

If you are sure:

Click on the help at the upper right corner of the screen from the account you want to delete.

Help /Account and password /Your Account Info / How can I delete my account

Then just follow the instructions

Yahoo Email Helpline

If you have more than one yahoo account sign out of the account you do not want to delete then open the one you do want to delete.

To delete your yahoo account go to:

http://help.yahoo.com/l/us/yahoo/mail/or...

https://edit.yahoo.com/config/delete_use...

OR

Stay out of your account for 4 months and yahoo will delete due to inactivity.

This will delete your whole account. It is a package deal with all of your other yahoo accounts (360, IM, Y!A, email, etc... ). All of your questions and answers that have gone into voting and that have been resolved will always be on here they are the property of yahoo. Hope this helps!!!
