Category:Languages without ISO 639-3 code

This is a maintenance category, used for maintenance of the Wikipedia project. It is not part of the encyclopedia and contains non-article pages, or groups articles by status rather than subject. Do not include this category in content categories. This is a hidden category. It is not shown on its member pages, unless the corresponding user preference (Appearance → Show hidden categories) is set.

This list is populated by writing none in the [iso3=] field of Template:Infobox language. This should be used to mean that no formal ISO 639-3 code is maintained at either Ethnologue or Linguist List / Multitree; that is, there is nothing to put in the [iso3] field of the infobox. Languages with provisional (non-ISO 639-3) codes at Linguist List / Multitree are listed in a subcategory.

Dialects of languages with ISO 639-3 codes should not be listed, as they are part of an assigned code; if they do appear here, the code 'none' should be removed from their infoboxes, or the parameter isoexception should be set to dialect. Similarly for historical forms and protolanguage (which as of 2013^{[needs update]} do not use infoboxes).

Neglected articles with fields left blank are listed at Category:Language articles without language codes.

As and if codes are assigned to these languages, the articles should be updated to remove them from this category. They should also be reviewed occasionally for new informal Linguist List codes.

Note: Ideally, this category would be populated only with subcategories, with any articles appearing here directly needing to be cleaned up. However, a couple articles that have multiple info boxes without ISO codes (e.g. Mekeo, Broken Slavey) appear here without needing to be cleaned up, due to the coding needed to avoid conflating the footnotes generated by the info boxes.
