Domain backorder is a service made available by ICANN-authorized service providers and it is the most efficient way to acquire a good domain name that was owned by some third party and was left to expire. When the registration period of a domain name has ended, the aforementioned becomes inactive, but is not removed immediately. Instead, its owner has a few months to renew it. In case this doesn't happen, the domain name enters a deletion period that lasts about five days and then it gets deleted, so anybody can register it. The backorder service allows you to make an order for such a domain with a registrar company and they'll attempt to register it immediately the second it's available. Thus, you will be able to get a brief and eye-catching domain name for your site and although such domains are registered on a first -come, first-serve basis and there is no guarantee that you will get the wanted domain name, using an automated system will provide you with a better chance than if you keep checking if the domain is erased and attempt to get it personally.
