Create a different Yahoo ID or email address

While you can't change your Yahoo ID or primary email address, you have the option to create an extra email address – a second Yahoo email address available with your existing Yahoo ID account. If this doesn't work for you, you can always start over and create a brand new Yahoo account. 

However, you can change your primary Yahoo email address for Yahoo Groups:

First, make sure that you’re signed in to the Yahoo ID in question.

  1. On the group's main page, click Membership | Edit Membership.
  2. Next to "Identity," click the Edit Settings icon Pencil.
  3. Select your desired email address.
  4. Click Save.  

Any email addresses linked to your Yahoo ID must be verified to be used with Yahoo Groups.
