https://steamcommunity.com/profiles/76561197960287930Why there are so many formats
SteamID64 is the 17-digit number used by the Web API and profile URLs. The legacy STEAM_0:Y:Z form comes from the original Source engine, where Y is the low bit of the account id and Z is the rest of it halved. SteamID3, written [U:1:x], carries the account id directly. All three describe the same account, so conversion is pure arithmetic — no lookup required.
Questions
- Which format should I use?
- SteamID64 for anything touching the Steam Web API or a profile link, STEAM_0:Y:Z for server configs and older tooling, [U:1:x] for anything reading modern game output. If a tool rejects one, it almost always wants another from this same set.
- Why can't it resolve steamcommunity.com/id/name?
- A custom URL is an arbitrary label Valve stores server-side; there is no formula from it to an account id. Resolving one requires a call to Steam's API with a key, which this page deliberately does not make. Open the profile, and the numeric /profiles/ URL will convert fine.
- Is anything sent to your servers?
- No. The page ships the conversion logic to your browser and runs it there. There is no request, no logging and no analytics on the input field.
