===ISO codes===
The international language-encoding standard [[ISO 639-1]] uses the code <code>fa</code> for the Persian language, as its coding system is mostly based on the native-language designations. The more detailed standard [[ISO 639-3]] uses the code <code>fas</code> for the dialects spoken across Iran and Afghanistan.<ref>{{cite web |url=https://iso639-3.sil.org/code/fas |title=639 Identifier Documentation: fas |publisher=Sil.org |access-date=5 March 2021 |archive-date=16 February 2022 |archive-url=https://web.archive.org/web/20220216202338/https://iso639-3.sil.org/code/fas |url-status=live}}</ref> This consists of the individual languages Dari (<code>prs</code>) and Iranian Persian (<code>pes</code>).
