hreflang="mn"

mn is a valid hreflang value for Mongolian.

Language: Mongolian (mn, ISO 639-1)

Example

<link rel="alternate" hreflang="mn" href="https://example.com/mn/" />

The code is case-insensitive for Google. The conventional spelling is a lowercase language, a title-case script and an uppercase region: mn.

Without a region, the annotation targets every Mongolian speaker regardless of country. Regional versions sit next to the language-only version in one cluster.
