Domain backorder is a service provided by ICANN-approved service providers and it's the easiest way to obtain a good domain that was owned by a third party and was left to expire. When the registration period of a domain name has expired, the latter becomes inactive, but isn't deleted instantly. Instead, its owner has a couple of months to renew it. Provided this does not happen, the domain enters a deletion period which lasts about five days and then it is deleted, so anyone will be able to register it. The backorder service enables you to place an order for such a domain name with a registrar company and they'll try to register it immediately once it's available. This way, you can get a brief and attractive domain for your site and although such domains are registered on a first -come, first-serve basis and there's no guarantee that you will acquire the desired domain name, using a computerized system will provide you with a significantly better chance than if you keep checking if the domain is erased and try to get it manually.
