How Can I Search For A Player By SteamID or Other Unique Identifier?
Searching for players by Steam64ID, IP, or other unique identifier is a feature that is only available to server owners and the administrators of those servers. We do not disclose information to anyone who does not have authority to view the information. Server owners only get access to information obtained from their servers.
If you are not a server owner, this feature is not available to you in any form.
Server owners can begin the search process on the /rcon/players page. When searching for identifiers, it is recommended that you wrap your search term with quotes to only return exact matches. See below for an example.
