The article Two-letter or three-letter language codes was rewritten to replace mentions of RFC 4647 with BCP 47, and add new links to further reading.

Bulgarian, Greek, Spanish and Polish translators should consider retranslating the article.

The article was updated as follows:

• applied new template and added cite tags
• changed two paragraphs in the answer section
• substantial changes to the Further Reading section

Thanks to the Spanish Translation Team, Spanish Translation US, the following articles have been translated into Spanish.

Códigos de idioma de dos o tres letras (Two-letter or three-letter language codes)

Thanks to Ivan Baldwin the FAQ-based article “Two-letter or three-letter language codes” has now been translated into Bulgarian.

Thanks to the microo.net editor team, Γιώργος Τσιλεδάκης, the FAQ-based articles “Multilingual Forms”, “Two-letter or three-letter language codes”, and “Non-English tags” have now been translated into Greek (language negotiated).

Thanks to the Tłumaczenia Angielski Team the FAQ-based article “Two-letter or three-letter language codes” has now been translated into Polish (language negotiated).

Since the publication of the new IANA Language Subtag Registry as the place to find language subtags, rather than the ISO code lists, this question is no longer relevant.

The article was almost completely rewritten to explain this.

The Portuguese translation has been removed, since the text is now so radically different.
