Steam Custom URL Checker
Steam has three different names: a private account name for signing in, a public profile name anyone can change, and an optional custom URL at steamcommunity.com/id/name. Only the custom URL is unique and public, so that is what this checker looks up.
Steam custom URL rules
| Account name | The sign-in account name cannot be changed, even by Steam Support. |
|---|---|
| SteamID | Every account has a fixed 17-digit SteamID64 that never changes. |
| Profile name | The player name shown to friends can be changed at any time under Edit Profile, and does not have to be unique. |
| Custom URL | Optional and set in Edit Profile. Clearing it shows your numeric profile URL again. |

How to check a Steam custom URL
- Enter the custom URL text you want, the part after steamcommunity.com/id/.
- We open steamcommunity.com/id/<name> and look for profile data. Steam returns an error page when no profile has that URL, which we report as "Not found."
- This does not reveal account names, which are private. A free custom URL says nothing about whether the same account name exists.
- Check by hand at steamcommunity.com/id/<name>; "The specified profile could not be found" means the custom URL is unused.
Steam custom URL taken? What you can do
- Add a number or a gaming word to the custom URL: miaplays, mia_gg.
- Your profile name does not need to be unique, so you can show the exact name you want while using a different custom URL.
- If an account impersonates you or a brand, report the profile from its page on Steam Community.
- Account names cannot be changed or merged, so if you dislike yours, the only route is a new account, and games do not transfer between accounts.
How to change your Steam custom URL
- Open your Steam Community profile and click Edit Profile.
- Change Profile Name to update the name people see.
- Fill in the Custom URL box to set or change steamcommunity.com/id/name, then save.
Reserved and restricted names
Profiles that pose as Valve staff or other players can be reported from the profile page on Steam Community. Account names are permanent, so choose one you are comfortable typing at every sign-in.
Tips
- Keep your account name different from your profile name and custom URL; it is a sign-in credential, and showing it publicly helps phishers.
- Old custom URLs stop working when you change them, so update links in forums and trading sites.
- Your 17-digit SteamID64 profile link always works, even when you change the custom URL.
