Polish is declared twice, by the two longest sets
Two of the nine vendors that declare a site language declare Polish, and they are the two vendors with the longest declared sets. Every shorter set in this register leaves it out. As of 2026-09-22.
| Vendor | Code as declared | Form of the code | The set it sits in |
|---|---|---|---|
| CapCut | pl-PL | Region-tagged | 27 locales, every one but English region-tagged |
| Kling AI | pl | Bare language code | 20 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.
1A language only the deepest sets reach
Unlike Italian or Dutch, which mark a European strategy, this code only appears once a set is already large. The 27-locale set has it and so does the 20-code set; the thirteen, nine, five and two-code sets do not.
That makes it a depth marker. A reader can use it as a quick test: a vendor declaring Polish has translated well past the core, and there are only two of those in this register.
2A large audience translated late
Poland has about thirty-eight million speakers, more than the Netherlands and Sweden combined, and both of those are declared at least as often. The ordering in this column tracks software spending rather than population.
One vendor writes pl-PL and the other the bare code. The language has one national standard, so the tag is confirmation rather than new information, which is the usual situation for the languages in this column outside the Iberian and Chinese cases.
3Neither vendor publishes the language of anything it generates
One of the two publishes a subtitle count and no voice list; the other publishes a voice count of five without naming the five. So for a Polish-language production this register has nothing beyond two translated websites.
The countries clustered with it, Czech, Hungarian and Romanian, are each declared by one vendor only. Central Europe is the thinnest part of this column that is covered at all.

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 single-vendor languages nearby are collected on one question page.
Languages either side of this one in the index: Malay and Portuguese. Every language any vendor declares is listed at one language at a time.
