How do I convert SteamID32 to Account ID?

Paste your SteamID32 into the converter above and the Account ID appears instantly. Worked through by hand: Multiply Z by 2, then add Y. That gives the account ID back. It is the account ID itself. For example, STEAM_0:0:26039975 becomes 52079950.

How the conversion works

Both formats describe the same underlying account, so the conversion is arithmetic rather than a lookup. Every Steam identifier is built from one 32-bit account number, and the route from SteamID32 to Account ID goes through it:

Start with the SteamID32. Multiply Z by 2, then add Y. That gives the account ID back. For STEAM_0:0:26039975 that gives an account ID of 52079950.
Build the Account ID. It is the account ID itself. That produces 52079950.

Worked example

Step	Value
SteamID32 in	`STEAM_0:0:26039975`
Account ID	`52079950`
SteamID64 equivalent	`76561198012345678`
Account ID out	`52079950`

What a SteamID32 is

The original textual format, written STEAM_X:Y:Z. X is the universe (almost always 0 or 1 for public Steam), Y is the lowest bit of the account ID, and Z is the account ID shifted right by one. Splitting the number this way is a quirk of the original implementation, not something meaningful.

Source engine servers and their tooling still live in this format. SourceMod's admins.cfg expects entries like "STEAM_0:1:12345678", most older ban plugins store it, and the SourceBans web panel has historically rejected newer formats outright. If you administer a Counter-Strike, Team Fortress or Garry's Mod server, this is the one you end up needing.

What a Account ID is

The bare 32-bit account number underneath every other format. Strip away the base offset and the textual wrapping and this is what remains — the actual identity.

The Dota 2 match history API uses it, several match-history and stats sites key on it, and it is the number shown in a Steam friend invite code. It is also the value you want if you are storing IDs compactly, since it fits in 32 bits.

Converting more than one ID

This page handles a single ID at a time. To convert a whole list at once — a ban file, an admin config, a spreadsheet column — use the bulk converter, which accepts mixed formats and custom profile URLs in the same paste.
