How to change my Steam ID

Unfortunately, it is not yet possible to change your SteamID or your Steam Account Name - even by Steam Support staff members.

It is however possible to modify your custom Steam Community ID, even if you have already configured one.

Your custom Steam Community ID can be changed at any time in your Steam Community settings, under "Edit my SteamID page", however doing so too frequently may make it difficult for your friends to stay in touch with you.
