How can i change my ymail account into yahoo.co.in or yahoo.com, name remains the same.?

No, it is not possible. You have to open a new account with Yahoo if you want that other domain. When you do that you will see if you can use that same name; if you can not change it slightly and try it again. Once you open the new account, you can transfer the information in the old account to the new account, inform all of your contacts of the new E-mail address, then you can close the old account if you wish. Go to the home page of the mail service you wish to open an account in. For yahoo, you want to go to your local yahoo.com and click on mail. Click on the 'Sign Up' link under 'Don't have a Yahoo! ID?' How to Import Contacts from other accounts: In upper right corner of screen, look for, then click on "Options:" Options/ mail options you will be in the 'general' section, click on 'contacts' in list on left of screen Click on 'transfer contacts to Yahoo' Re-enter your password, then a permissions page, then the TOS page. Click 'Start Transfer.' Enter your ID name for old E-mail account, pick the domain of old account. Enter your old password, click next. You may need to enter the ID name, provider and password again, if they need to verify anything Now check the information you want to transfer to your Yahoo! account. As many as you can, as you can only do this once. You can also send a note to your contacts of the new E-mail address. Check mark box beside, 'Send a note,' if you want your own note, click 'Click here to personalize.' Click on 'Next'. Click on 'Next' to transfer the information. The 'Finished' page will confirm transfer. It could take as long as 24 hours to complete this transfer. 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.

You'll have to create a new account. The current one you have now can't be changed because of security reasons. Go do that here: https://edit.yahoo.com/registration? Conversely, you can create an extra email address under your current account by going here: http://edit.yahoo.com/config/list_alias

possible. but you have to pay.
