The hosting account name is used to identify it within the hosting system. It can be seen in the section "Hosting»: It is set only at the time of ordering a hosting account, it is unique and cannot be changed for an existing hosting account.
Where it appears:
The name of the hosting account does not affect the operation of sites and their position in search engines.
To make it easier to navigate among the hosting accounts, you can set a custom name (alias) for each of them using the edit button next to the name. This function only changes the way the hosting account name is displayed in the "Hosting". The custom name has no effect on file system paths, host addresses, and user prefixes.
