人工語言代碼(Codes for constructed languages)為個人人工語言的ISO 639代碼及IETF語言標籤(IETF language tag、BCP 47)之列表，完成於2009年11月。ISO 639-2與ISO 639-5也為其他人工語言建立<art>代碼。 BCP47中同樣具有子標籤的<art->代碼，連同子標記<-x->可以被用來為尚未被分配到官方語言標籤的人工語言創建一個合適的私人使用標籤(例如:"art-x-solresol"可用於表示索来索语，或"art-x-Latino-sine-flexione"用於表示无屈折拉丁语)。

舊的SIL國際語言標識符(通常用大寫)已正式過時了，不再被使用。他們形成ISO 639-3語言代碼的基礎，但在ISO 639-3建立之前的一些SIL標識符已不再使用、而且之後被分配到ISO各個不同的語言之間。IANA語言子標記註冊(定義在BCP 47的IETF語言標籤)已於2009年7月29日更新，包括所有在那個時候使用的ISO 639-3和ISO 639-5標識符。

註釋

^ ^1.0 ^1.1 ^1.2 The old BCP 47 language tags i-enochian, i-klingon and art-lojban are old tags that were grandfathered in. The last two are also deprecated in preference to the later three-letter codes.
^ The ISO 639-3 standard previously included the code eur for Europanto, which was retired on 2009-01-16, with the reason “Nonexistent”.[1] （页面存档备份，存于互联网档案馆）.
^ ISO 639-3 used to have the code occ for Occidental. This was retired on 18 July 2007, because Occidental is just another name for Interlingue, which has the code ile.
