tt is a valid hreflang value for Tatar.

Language: Tatar (tt, ISO 639-1)

Example

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

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

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