How can you change your name in Yahoo id?

Answer 1

You can't change your user name, but there is option that you can add another account, like add-on account with desired id and the same you can receive mail as like as earlier mail. The current mail in Box is same for both id and while sending mails, you have to select from which ID you want to send the mail. One drop down list will come, you have to choose one of them and send from that ID.

You can receive mail from Both id's, because the inbox is same.

Option ----------> Mail Accounts------------> add extra mail. Choose this option to add new ID, that ID should be available in the list.
