When you own a domain name that is important for your business or is otherwise very important to you and you do not wish to lose it, the best solution would be to register it for more years. Can you do that? Unfortunately, there is no universal answer to that question because different rules apply for different domain name types (TLDs).
Most domain names can be registered for up to 5 or 10 years ahead. When you register or renew a domain name that can be regsitered for more years, you will see that option during the very order procedure.
There are domain names that must be registered for a minimum of two or three years and those that can be registered for a period of two years only – no more, no less. There are also other domain names that can be registered for one year only and must be renewed every year in order to keep the given domain name.
What is important to know is that when you order a domain registration or renewal, you will be always given the option to select the registration period as long as the specific domain type (TLD) allows it.
