Windows code page 932 is registered with the [[Internet Assigned Numbers Authority|IANA]] as '''Windows-31J'''.<ref name="iana31j">{{cite web | url=https://www.iana.org/assignments/character-sets/character-sets.xhtml | publisher=IANA | title=Character Sets}}</ref> The "Windows-31J" label is IANA's and not recognized by Microsoft, which has historically used "shift_jis" instead.<ref name="msdnlabels">{{cite web|url=https://msdn.microsoft.com/en-us/library/system.text.encoding.windowscodepage(v=vs.110).aspx |title=Encoding.WindowsCodePage Property - .NET Framework (current version) |work=MSDN |publisher=Microsoft}}</ref> The [[W3C]]/[[WHATWG]] encoding standard used by [[HTML5]] treats the label "'''shift_jis'''" interchangeably with "windows-31j" with the intent of being "compatible with deployed content"<ref>{{cite web | url=https://encoding.spec.whatwg.org/#names-and-labels | title=4.2.

Windows code page 932 is also called '''MS_Kanji''',<ref name="icuwindows31j" /><ref name="python">{{cite web | url=https://docs.python.org/3.6/library/codecs.html#standard-encodings | title=7.2.3.

In Japanese editions of Windows, this code page is [[Windows code page#ANSI code page|referred to as "ANSI"]], since it is the operating system's default 8-bit encoding, even though [[ANSI]] was not involved in its definition.
