Localizing your app listing into Korean

Storefronts and localization names read from Apple’s App Store localizations reference; language codes and field limits from Google Play’s translation language list and each store’s field reference. Checked August 29, 2026.

South Korea is a default-Korean storefront and a heavy-spending one, and Apple attaches a market-specific requirement to it: some apps need a Rating Classification Number from the Game Rating and Administration Committee before they can be offered there at all.

Hangul is three bytes per character, so the 100-byte keyword field is roughly 33 Korean characters — plan the keyword list before translating rather than trimming afterwards.

Where a Korean listing appears

Apple publishes the default language of all 173 App Store storefronts. Korean is the default in 1 of them, and an additional supported language in 1 more.

What you translate, and what it costs you

Both stores cap the same fields, and neither cap changes by language — but the amount of meaning you fit inside them does. Apple’s keyword field is the one that surprises people: it is measured in bytes, so Hangul at about 3 bytes per character leaves roughly 33 characters. Google Play counts characters instead, and says so explicitly: its limits “apply to both full-width and half-width characters”.

The screenshots are part of the localization

Both stores let you upload a separate screenshot set per localization, and in practice the captions are what sells — a translated description under English screenshots converts like an English listing. Design the frames once, then export the same layout per language rather than rebuilding it: that is the difference between localizing into Korean in an afternoon and not doing it at all.
