Unfortunately, renaming your domain name is a process that cannot be performed. Once a domain name is registered it remains active and cannot be renamed or deleted until it expires and is cleared from the registry after the "PendingDelete" status. There is a very small window of 24-72 hours in which certain TLDs can be deleted but you need to act really quickly if you want to take advantage of this option.
If you have made a typo while writing down your domain during the registration or you simply had a change of heart within the timeframe mentioned above, please contact our Technical Suppor team via the ticketing system. Alternatively, you may reach our live chat representatives on our website by opening the chat function on the bottom right corner.
