hreflang="az"

az is a valid hreflang value for Azerbaijani.

Language: Azerbaijani (az, ISO 639-1)

Example

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

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

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