Russian is declared five times, and tagged to Belarus once
Five of the nine vendors that declare a site language declare Russian. Four use the bare code. The fifth declares it only as ru-BY, which names Belarus, so no declaration in this register names Russia itself. As of 2026-09-22.
| Vendor | Code as declared | Form of the code | The set it sits in |
|---|---|---|---|
| CapCut | ru-BY | Region-tagged | 27 locales, every one but English region-tagged |
| Kling AI | ru | Bare language code | 20 bare codes |
| PixVerse | ru | Bare language code | 13 bare codes |
| SceneMixer | ru | Bare language code | 15 codes, one of them script-tagged |
| Vidu | ru | Bare language code | nine bare codes |
Inclusion rule. Vendors declaring this language as a same-host hreflang alternate. A vendor serving the language without declaring it cannot be seen by this method and is not listed. Order. Alphabetical by vendor.
1The one region tag points at the smaller market
Belarus has under ten million people; Russia has well over a hundred million speakers of the language, and it is widely used across several more countries. One vendor has tagged its Russian page to the smaller of those markets and nobody has tagged one to the larger.
The register records the code as written and does not normalise it. A reader who wants to know why can ask the vendor; what this column can say is that the narrowest Russian declaration here is also the only specific one.
2Four bare codes, and one absence worth noting
The four bare declarations say only that the pages are in Russian, which for a written marketing page is close to sufficient: the written standard does not vary much across the countries that use it.
Two of the three longest declared sets include the language and the third does not. Neither of the two nine-code sets agrees with the other about it, which is part of why those two sets share only five codes between them.
3Ukrainian is declared three times, by an overlapping group
The neighbouring language in this column is declared by three vendors, two of which also declare this one. So the two are not alternatives in the way a reader might assume; the deeper sets take both.
Neither language appears in any published voice list here. For a Russian or Ukrainian language production, this register holds site declarations and nothing else.

Each row was read from the vendor's own markup on 2026-09-22 and is kept in the register; what counts as a declaration is on how counted. The neighbouring code is read at the Ukrainian page.
