How can I renew a domain name that is registered by SiteGround?
You can renew your domain name registered through SiteGround from your User Area > My accounts > Domain names.
Domain names registered together with a hosting account purchase are renewed along with the hosting account renewal itself. There is no need to renew such domain names separately. If you wish to discontinue the hosting but keep there is no problem in doing so. In this case however you will have to process future domain name renewals separately.
All other domain names have to be renewed separately. All SiteGround services including domain names are set on automatic renewal billing. This means that we will attempt to bill you automatically when your renewal is due.
