If you registered a domain through Yahoo!, we'll automatically rewew your domain each year. If your billing information is up-to-date, there's no need to do a thing.
You can double-check your billing information by visiting https://billing.yahoo.com. To update your credit card, click the "Update Payment Method" link next to the plan you'd like to edit. Learn more.
Important: If you're using a domain that you registered with another company, that company will continue to renew your domain, and you'll pay any associated fees to that provider. Yahoo! will not renew your domain.
