If you registered your domain name through Yahoo! or transferred the domain registration to Yahoo! and the service is still active, we will automatically renew your domain each year (or, in the case of multiyear Yahoo! Domains registrations, at the end of your term). If your billing information is up-to-date, there's no need to do anything.
You can review and update billing information at Yahoo! Wallet.
Important: If you're using a domain that is registered with another company, that company will be responsible for renewing the domain, and you will pay any associated fees to that registrar.
