SteamID Formats Explained (SteamID64, STEAM_X:Y:Z, SteamID3)
Direct answer: Use SteamID64 (17 digits) or a full Steam profile URL when you need a reliable player lookup or report target. The older formats (STEAM_X:Y:Z and [U:1:Z]) can refer to the same account, but they’re easier to mistype and not every tool accepts them directly. If you’re unsure, paste the full profile URL first, then convert to SteamID64 if needed.
Quick Reference
- SteamID64: 17-digit number. Most reliable to paste.
- Profile URL:
https://steamcommunity.com/profiles/<steamid64> - Custom URL (vanity):
https://steamcommunity.com/id/<name>(can change) - Steam2:
STEAM_1:0:123456 - Steam3:
[U:1:246912]
How Conversion Works
All three formats (SteamID64, Steam2, Steam3) point to the same account. The conversion is a simple arithmetic mapping. Tools like SteamReport automatically resolve whichever format you paste, but starting with SteamID64 or a full profile URL avoids edge cases with older format parsing.
Common Mistakes
- Pasting a display name (not unique) instead of a profile URL/ID.
- Copying only part of a URL (missing
/profiles/or the digits). - Using a custom URL that no longer points to the same account.
- Extra spaces or punctuation around the identifier.
