A SteamID is a unique identifier used to identify a Steam account. It is also used to refer to a user's Steam Community profile page.
Format
As Represented Textually
SteamIDs follow a fairly simple format when represented textually: "STEAM_X:Y:Z", where X, Y and Z are integers. In select cases "STEAM_ID_PENDING" or "UNKNOWN" are used (see the section 'Types of Steam Accounts' for more details).
- X represents the "Universe" the steam account belongs to.
- Y is part of the ID number for the account. Y is either 0 or 1.
- Z is the ID number for the account (the "account number").
As Represented in Computer Programs
When represented internally in computer programs the X, Y and Z components (see the section titled 'As Represented Textually') are all packed into a 64-bit data structure.
- The low 32 bits represents the ID number for the account (the "account number").
- The next 20 bits represents the instance of the account. It is usually set to 1 for user accounts.
- The next 4 bits represents the type of account.
- The next 8 bits represents the "Universe" the steam account belongs to.
Universes Available for Steam Accounts
There are 8 universes of Steam accounts.
| Number | Type |
|---|---|
| 0 | Individual / Unspecified |
| 1 | Public |
| 2 | Beta |
| 3 | Internal |
| 4 | Dev |
| 5 | RC |
Types of Steam Accounts
There are ten known account types for a Steam account, of which only 3 can be created today.
| Number | Letter | Type | Can Be Used? |
|---|---|---|---|
| 0 | Invalid | No | |
| 1 | U | Individual | Yes |
| 2 | Multiseat | Yes | |
| 3 | GameServer | Yes | |
| 4 | AnonGameServer | Yes | |
| 5 | Pending | No | |
| 6 | ContentServer | Unknown | |
| 7 | g | Clan | Yes |
| 8 | T | Chat | Yes |
| 9 | P2P SuperSeeder | No | |
| 10 | AnonUser | No |
Users of an 'Individual' account are temporarily referred to as having a 'Pending' account which have a textual representation of "STEAM_ID_PENDING" until their account credentials are verified with Steam's authentication servers, a process usually complete by the time a server is fully connected to. Accounts of the type 'Invalid' have a textual representation of "UNKNOWN" and are used for bots and accounts which do not belong to another class.
Steam ID as a Steam Community ID
A Steam ID can be converted to Steam Community ID for use on the Steam Community website by applying the following formula to the SteamID:
- Let X,Y, and Z be defined by the Steam ID: STEAM_X:Y:Z
- Let SteamCommunityID be steamcommunity.com/profiles/SteamCommunityID
unsigned long long SteamCommunityID = (Z*2) + 76561197960265728 + Y
By performing the reverse operation, a Community ID can also be converted to a Steam ID.
Caveat about Cyber Café Accounts
Although it would appear sensible for Valve to put all cybercafé account SteamID's in their own universe, this has not been done. Instead, cybercafé accounts got SteamID's in the same universe as user accounts, typically from a large pool of SteamID's where the unique ID part lies within the range 7000000 and 8000000. There are also non cybercafé accounts within this range and cybercafé accounts outside of this range.
SteamID Uses
Aside from the obvious elements of identifying (uniquely) an account, its type and the domain (universe) it belongs to, SteamIDs can be used to approximately determine when the user associated with the SteamID first created that Steam account. Lower values of 'Z' in the format described above (i.e. the account number) indicate an account made further in the past to one with a higher value. For example, a SteamID like STEAM_0:0:1234 would mean that the user signed up for their Steam account a long time before a user with a SteamID such as STEAM_0:0:12341111.
The value of X is 0 in VALVe's GoldSrc and Source Orange Box Engine games (For example, Counter Strike: Source), but latest Valve games such as Left 4 Dead, Left 4 Dead 2 and Alien Swarm have 1 as a value of X. The value of Y is normally 0 or 1, which used to be the authentication server the user is on, but now it is just part of the Account ID.
