When loading the interface, the WoW client skips over any addons whose interface version does not match its own. This is an effort to keep the client's behavior free of errors due to changes in the API. Each addon specifies (in its [[TOC format|.toc file]]) the interface version with which it complies. So an addon's .toc file most likely contains a line similar to:
The WoW 'interface number' is important for WoW [[AddOn]]s and can be difficult to find.
## Interface: 20400
Here, 20400 would mean that the addon is designed against the [[Patch 2.4]] client (and any subsequent minor releases).

← HOWTOs

The WoW 'interface number' is important for WoW AddOns and can be difficult to find.

Interface number basics[edit]

The WoW 'interface number' is the current version for the actual UI in WoW. AddOns use this number in their own TOC file to denote the WoW user interface they were created for.

By default the WoW client skips over any AddOns whose interface version does not match its own. This is an effort to keep the client's behavior free of errors due to changes in the API.

In the AddOn TOC file: 

## Interface: 70000

Interface number 70000 would mean that the AddOn is compatible with WoW Patch 7.0.3. The same interface number can be used for a series of WoW patches, usually until the next 'minor' release version. For example for with WoW Patch 7.1.0, 70100 would likely be the new interface version number.

Editions, patches and PTRs[edit]

With the addition of WoW Classic and now having two different WoWs, there are now multiple TOC interface version numbers "live" at the same time. WoW 'Classic' uses the older versions similar to the versions of the original game, starting with 1.X, and has differently numbered versions from 'Retail' which is the name for regular WoW.

The truth is that there are were always multiple versions of WoW, as far as PTRs, betas and so forth. But each version now has its own distinct folder under the World of Warcraft install folder, like '_retail_', '_classic_', '_ptr_'. Each of those folders has a its own set of 'WTF', 'Interface/AddOns', and other files and folders. Keep this in mind when using the following ways below.

Two versions[edit]

If an addon is released for both classic and retail, and wanted matching numbers for each to load without the out-of-date warning, there need to be two copies. There would need to be a retail release with the retail TOC version, and classic release with the classic TOC version.

Finding the number[edit]

There are a number of ways to get the current interface version:

1. Wiki patch notes[edit]

See the latest 'patch notes' and look for the 'Interface' number in the Patch box.
This is the most authoritative source on the Wiki.

2. 'API LatestInterface' wiki template[edit]

The WoWWiki 'Interface Version' template {{API LatestInterface}}
But this number is maintained manualy, so it might be out of date.

3. WoW major minor version[edit]

The interface number is usually derived exactly from WoW 'major.minor' version. Sometimes is derived from 'major.minor.release'.
In 2.4.0, where 2 is the major version number, and .4 is the minor version number, is 20400. 5.4.0 is 50400 and, 5.4.1 (.1 being the 'sub-minor' or 'release' version) would likely be 50401. However, Blizzard doesn't often distinguish on the sub-minor version level, so you would still use 50400. However with patch 8.2.5, for example, the interface number is actually 80205.

4. WoW FrameXML.toc[edit]

Extract and check FrameXML.toc (no longer works, interface number is no longer in the FrameXML.toc). See Extracting WoW user interface files.
or DEPRECATED, not updated since Oct. 2010 You can download Blizzard's User Interface Customization tool], use it to extract interface data, and peek at 'World of Warcraft\Blizzard Interface Data (usUS)\FrameXML\FrameXML.toc'. See Interface AddOn Kit for history of the tool kit.

5. From another AddOn[edit]

Steal it from another AddOn
Recently updated AddOns, which are not listed as "out of date" by the client contain the latest Interface version in their toc tag.

6. 'lastAddonVersion' in Config.wtf[edit]

Find the 'WTF/Config.wtf' file in your 'World of Warcraft/_retail_' or 'World of Warcraft/_classic_' folder, then the 'lastAddonVersion' CVar
This is the most authoritative source for the interface number.
Must run WoW at least once after install or patch for this to show up.

7. The Wow API GetBuildInfo[edit]

Use GetBuildInfo to verify the 'major.minor' version number.
/run print((select(4, GetBuildInfo())))
Above should output the WoW build version to your chat frame.

8. WoW FrameXML.toc on the Web[edit]

View FrameXML.toc online (no longer works, interface number is no longer in the FrameXML.toc) For example: FrameXML.toc [tly].

Notes[edit]

  • In the past Extract FrameXML and check FrameXML.toc - DEPRECATED, not updated since Oct. 2010
  • In the past you could also download Blizzard's User Interface Customization tool, use it to extract interface data, and peek at World of Warcraft\Blizzard Interface Data (usUS)\FrameXML\FrameXML.toc
