How do I change my steam username or contact steam support?

[JimmyBear217]

Hi,
i've been trying to change my username for months but i cannot find how to do it, nor an email or ticketing system to ask valve support to do it for me.
Can somebody please indicate me a way to do it or a path to contact the support team?
thanks.

Your log-in or your display name?

You can't change your log-in name.

You can change your display name under "Edit Profile" on your profule.

Can my SteamID and/or Steam Account Name be changed?
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".
