Frequently Asked Questions
What are the different Steam ID formats?
Steam uses four ID formats: SteamID (STEAM_0:0:12345 — the original format), SteamID3 ([U:1:24690] — newer compact format), SteamID64 (76561197960290418 — 17-digit numeric ID used in APIs), and the profile URL (steamcommunity.com/profiles/76561197960290418). All represent the same account.
How is SteamID64 calculated from SteamID?
SteamID format is STEAM_X:Y:Z. The SteamID64 is calculated as: 76561197960265728 + Z×2 + Y. The base number (76561197960265728) is a constant representing the Steam universe offset. This conversion uses BigInt arithmetic for precision.
Why would I need to convert Steam IDs?
Server admins need specific formats for ban lists and configs (often SteamID or SteamID3). The Steam Web API requires SteamID64 for all requests. Players sharing profiles use profile URLs. Converting between these saves time and avoids errors.
Can I convert a custom Steam URL (vanity URL)?
This tool converts between numeric Steam ID formats. Vanity URLs (steamcommunity.com/id/username) require an API call to resolve because the username-to-ID mapping is stored on Steam servers. Enter the numeric profile URL or any SteamID format instead.
