The Complete Guide to Steam IDs

A Steam ID is a unique, permanent number that identifies a Steam account. It never changes, even when you change your username. The same account can be written in several formats (SteamID64, SteamID2, SteamID3, Steam Hex, and a 32-bit account ID), which is where most of the confusion comes from. This guide explains each format, where to find it, and how to convert between them.

Ever been asked for your SteamID64 and had no idea what it was? You're not alone.

What is a Steam ID?

A Steam ID is a unique, permanent number that identifies a Steam account. It never changes, even when you change your username. Think of it as a serial number for your profile: your public display name can be updated at any time, but the underlying Steam ID is fixed forever.

This permanent identifier is what websites and game servers use to reliably track your account. It powers third-party stat-tracking sites, server admin and ban lists, trade offer links, and any service that connects to your Steam profile. The confusion arises because the same account can be written in several different formats depending on where it is used.

For a full technical breakdown of the encoding, see the official Valve Developer SteamID reference.

How to Find Your Steam ID

The fastest way to find your Steam ID is to paste your profile URL or custom URL into the finder on our homepage, which returns every format at once.

You can also find it directly in the Steam desktop client:

  1. Click the Steam menu in the top-left corner of the client, then click Settings.
  2. In the Settings window, go to the Interface tab.
  3. Enable "Display Steam URL address bar when available" and click OK.
  4. Click your username in the top-right corner and select "View my profile".
  5. The address bar at the top of your profile page will show a URL ending in a 17-digit number. That number is your SteamID64.

If you see a name instead of a number in the URL (for example /id/gabelogannewell/), you have a Custom URL set. Paste that URL into our lookup tool to get all formats.

On mobile, the Steam app does not show your Steam ID directly. Open your profile in any browser and read the 17-digit number from the URL, or use the finder above.

Understanding SteamID64 (Community ID)

A SteamID64 is a 17-digit number that uniquely identifies a Steam account and is the most widely used format today. When a website or service asks for your "Steam ID", it almost always means this format.

  • Example: 76561197960287930
  • Primary uses: Linking your Steam account to third-party services (stat-tracking sites, Discord bots, game databases), modern server whitelists and admin plugins, and all Steam Web API calls.

You can find any account's SteamID64 by pasting their profile URL or vanity URL into our lookup tool.

Understanding SteamID2 / SteamID32 (Legacy ID)

SteamID2, also called SteamID32 or Steam2 ID, is the legacy text format that looks like STEAM_0:0:11101. The digit right after STEAM (the universe) and the first digit after the colon (0 or 1) are part of the encoding. The bare 32-bit account number (22202 in this example) is sometimes what people mean when they say "SteamID32".

  • Example: STEAM_0:0:11101
  • Primary uses: Admin and ban lists for older Source engine games including Counter-Strike 1.6, Counter-Strike: Source, and the original Team Fortress 2. Some dedicated server configurations still require this format.

Understanding SteamID3 (Modern ID)

SteamID3 is a standardized text format used internally by Valve and in several modern tools. It is more compact and readable than SteamID2.

  • Example: [U:1:22202]
  • Primary uses: Steam trade offer URLs, newer developer tools, and any context where a human-readable account identifier is preferred over the long SteamID64 number.

Understanding Steam Hex (FiveM)

A Steam Hex ID is the SteamID64 written in hexadecimal, for example 110000105bdca75. It is used by FiveM and some game servers to identify players. Our tool converts Hex to and from every other format.

Understanding Custom URLs (Vanity URLs)

A Custom URL is a personalized vanity link that replaces the default SteamID64-based URL on your Steam profile. It is a pointer to your profile, not a Steam ID itself, and can be changed at any time.

  • Example: https://steamcommunity.com/id/gabelogannewell/
  • Important note: Because a Custom URL can be changed or reassigned, it is not a reliable permanent identifier. Services and servers that need a stable ID should always use the SteamID64.

Our tool resolves any Custom URL to its underlying SteamID64 and all other formats instantly.

How to Convert Between Formats

Paste any format (SteamID64, SteamID2, SteamID3, Custom URL, or Steam Hex) into the main lookup tool on our homepage to see every conversion at once. For a list of IDs, use the Bulk Steam ID Converter.

How the math works

For developers and server admins who want to understand the encoding:

  • From a SteamID2 of STEAM_X:Y:Z, the 32-bit Account ID = (Z × 2) + Y.
  • SteamID64 = Account ID + 76561197960265728 (the base constant 0x0110000100000000 for individual accounts).
  • SteamID3 = [U:1:AccountID].

Worked example using STEAM_0:0:11101 (X=0, Y=0, Z=11101):

  • Account ID = (11101 × 2) + 0 = 22202
  • SteamID64 = 22202 + 76561197960265728 = 76561197960287930
  • SteamID3 = [U:1:22202]

Is It Safe to Share Your Steam ID?

Yes. A Steam ID only points to public profile information that anyone could already see by visiting your profile. It cannot be used to log in to your account, change settings, or access anything private. Your account security depends on your password and Steam Guard, not your Steam ID.
