s&box Steam ID Resolver
Convert any Steam profile URL, vanity URL, SteamID2 (STEAM_0:0:...), or SteamID3 ([U:1:...]) into the SteamID64 format that users/config.json and most server tools require. All formats shown side-by-side with copy buttons.
Auto-detects SteamID2 / SteamID3 / SteamID64 / profile URL / vanity URL — vanity names are resolved through Steam Community's public XML endpoint.
What's a SteamID64?
SteamID64 is the 17-digit numeric form that Valve's internal systems use to identify a Steam account. It's also what most game-server admin files want — including s&box's users/config.json, The Isle's admin/whitelist, and most BattlEye / RCON allow-lists across the industry. Players see different formats in different places (legacy STEAM_0:0:1, the bracketed [U:1:W], profile URLs, custom vanity names) so a one-stop converter saves a surprising amount of friction.
The Steam ID Formats
| Format | Example | Where you see it |
|---|---|---|
| SteamID64 | 76561197960287930 | Modern admin files, Steam Web API, profile URLs (/profiles/). |
| SteamID3 | [U:1:22202] | Source-engine console, server query tools. |
| SteamID2 | STEAM_0:0:11101 | Legacy. Common in old GMod / CS:S configs. |
| Profile URL | /profiles/7656119... | Numeric URL — copy-pasteable as-is. |
| Vanity URL | /id/gabelogannewell | User-set custom URL — has to be resolved via Steam Community. |
How the conversion works
SteamID64 is just 76561197960265728 + W where Wis the account number. SteamID2 splits W into two halves: its lowest bit becomes the "Y" (auth server) and the rest becomes "Z" (account number). SteamID3 just shows the raw W in brackets. Vanity URLs (/id/<name>) are unique per-account and can only be resolved by Steam itself — this tool fetches a small public XML endpoint Steam provides for that.
