When a domain is not renewed before its expiry date, and the owner of a domain has failed to renew it during the grace period (around 30 days), the status of a domain is listed as ‘Pending Delete.’ It will stay at this stage for around five days. While it is too late to renew a domain name for the current owner at this stage, people, domainers and companies are allowed to ‘backorder’ domains listed as ‘Pending Delete.’
It will allow them to buy the ownership of a domain the second the five days are up. If multiple people are looking to purchase a domain name listed as ‘Pending Delete,’ an auction will be held. If nobody buys a domain listed as ‘Pending Delete,’ it will be put back up for registration and anyone can do so.
