How to change user ID that?

You can't change your ID. You may get an Extra Mail Address. It's not a separate Yahoo! ID or a separate Yahoo! Mail account. It's just another address you can use to send and receive email, and any messages you get go into the same Inbox you already use. You can also log in with that address.You can only have one extra mail address at a time. If you decide to change it, you can delete it and create another one. You can only change it twice within the next 12 months.
