This article address common questions such as:

• Why did my domain change?
• Can I change my Yahoo! domain? 

Here are some common concerns regarding your Yahoo! domain extension:

You would like to change the domain of your Yahoo! address to something different:

The domain of your Yahoo! Mail address is determined by the Yahoo! site through which you sign up for an account and also by the language preference you select at the time of registration. Currently, it is not possible to change the domain of your existing Yahoo! email address.

You do have the option of creating either a non-country specific domain or a country-specific domain.

• If you would like to sign up for a different account without the country-specific extension (for example, yahoo.com, rocketmail.com or ymail.com), please register through Yahoo!'s main page. From the main page, select U.S. English as your language preference. This will cause the domain name for the account you are creating to be yahoo.com instead of yahoo.co.uk, for example. Note: you will be able to change the language preference through your account information once the account has been established.
• For a country specific domain, please go to the Yahoo! page for the country you would like your domain to reflect. For example, go to Yahoo! UK for a yahoo.co.uk domain, and click Sign up to register your new account.

The domain of your Yahoo! Mail address has changed:

Previously, our system was set to allow email to a Yahoo! ID to be delivered regardless of the domain to which it was addressed. Our policy changed with the addition of the ymail.com and rocketmail.com domains. Emails addressed to your Yahoo! ID with an incorrect international domain are no longer redirected to the appropriate Yahoo! ID and domain.

For example, if your Yahoo! account is "person@yahoo.co.uk", and someone addresses a message to "person@yahoo.com", in the past, our system would automatically route the message to the ".co.uk" address. An email sent to the incorrect domain will no longer be delivered, and the person who sent the email should receive a notification that the message could not be received. 

To sign up for a specific regional account, see our list of available countries and register an account through the Yahoo!
site selected.
