Where can I find my SteamID? Can I change my SteamID or Steam Account Name? Can I merge two accounts? Can I delete my Steam account?
SteamID refers to your Steam account's unique numeric identifier. The instructions below will help you find your SteamID - for assistance with the Steam Community, please see the Steam Community topic.
SteamID example: STEAM_0:1:1234567
Your SteamID and Steam Account Name can not be changed, even by Steam Support staff members. Your player name can be changed at any time in your Steam Community settings, under "Edit my SteamID page".
Steam accounts can not be merged together.
Per the Steam Subscriber Agreement, Steam game subscriptions / CD keys are nontransferable and cannot be reset / moved between Steam accounts.
If you are sure that you don't want to use Steam anymore, you can submit a Steam Support request to terminate your account. Steam Support will ask that you provide comprehensive Proof of Ownership prior to fulfilling the request.
More details can be found in our Account Termination - Common Questions FAQ.
