Launching an adult-only game in South Korea requires more than completing a global age-rating questionnaire. Games that meet Korea’s Youth Restricted classification—commonly displayed as 19+ on digital storefronts—generally require an official Korean rating certificate before they can be distributed to adult users in the country.
A platform-generated age label alone may not satisfy this requirement. Global developers should prepare the Korean rating application, supporting materials, local filing structure, and store integration process before setting a launch date.
Korea’s statutory adult-game category is called “Youth Restricted,” rather than “18+” or “Adults Only.” Digital storefronts commonly display this category as 19+.
The Korean rating review considers content factors including:
A game may require a Youth Restricted rating when these elements exceed the standards permitted for younger audiences. Gambling-style mechanics and certain casino simulations may also trigger additional review requirements.
Not by itself.
IARC and platform questionnaires can generate region-specific age ratings for games distributed through participating digital storefronts. However, if a game falls within Korea’s Youth Restricted category, a platform-generated rating label alone may not be sufficient.
The developer may need to obtain an official Korean rating certificate and provide the relevant Rating Classification Number to the applicable storefront.
This does not mean that all IARC ratings are invalid in Korea. Platform-based classification remains available for eligible games below the Youth Restricted threshold. The additional certificate requirement primarily affects games classified as unsuitable for minors.
Before preparing the submission, determine:
Foreign companies generally cannot complete a direct Korean rating application using only their overseas corporate information. They typically need a Korean publisher, authorized filing representative, or Korean branch that can access the local application system and provide the necessary registrations.
A rating-application representative is different from the statutory Domestic Agent appointed under Korea’s Game Industry Promotion Act. Developers reviewing that separate obligation can read A Complete Guide: Choosing the Right Local Agent for Overseas Game Developers in Korea.
The exact documents may vary according to the platform, game structure, and review route. A typical submission package includes the following materials.
Prepare a clear explanation of:
The description should reflect the actual review build. Material discrepancies between the submitted documentation and the live game can create additional review or post-launch compliance risks.
Provide gameplay footage that allows reviewers to understand the complete game flow and all rating-relevant content.
The video should clearly show applicable scenes involving:
There is no universal rule that every submission video must be exactly ten minutes long. The footage should instead be long and detailed enough to demonstrate all relevant mechanics, with timestamps or annotations identifying important scenes.
A promotional trailer alone is generally insufficient.
Depending on the review process, developers may need to provide:
Reviewers should be able to reproduce the gameplay described in the application without unnecessary technical barriers.
For games containing substantial dialogue, story content, voice acting, or user-facing text, prepare the relevant scripts and localized materials.
This may include:
The required scope depends on the game. A complete dialogue script should not be treated as an identical requirement for every type of game, but all text affecting the rating must be reviewable.
The application package may also require:
Before filing, compare the application materials against the actual build.
Check that:
Incomplete or inconsistent materials are more likely to result in supplementary requests and launch delays.
After the application and supporting materials are submitted, the applicant must pay the applicable review fee and monitor the submission status.
The rating regulations generally provide for a decision within 15 days after receipt of the application. However, time spent correcting documents, supplying additional materials, resolving build-access problems, or completing certain technical-review procedures may not count toward that period.
Developers should therefore avoid treating 15 days as a guaranteed launch timeline. A reasonable operational buffer should be built into the release schedule.
If reviewers request supplementary information, respond with:
Once the review is completed, the applicant receives the official rating decision and Rating Classification Number.
Before proceeding to store integration, confirm that the certificate correctly identifies:
Any differences involving localized titles, publisher names, package identifiers, or platform information should be identified and resolved before store submission.
Store requirements differ, so developers should follow the current instructions provided by each platform.
Complete the content-rating questionnaire in Play Console and provide the official Korean rating certificate through the applicable Google Play review or advance-notice channel when required.
Games containing gambling or casino-style elements may be blocked from Korean distribution if the necessary certificate is not provided.
Complete the age-rating questionnaire in App Store Connect and provide the official Korean Rating Classification Number through the Korea-specific rating workflow where applicable.
The certificate information, developer details, and store submission should remain consistent.
One Store and other distribution platforms may require an IARC certificate ID, Korean rating certificate, or additional matching process. Confirm each store’s current requirements instead of assuming that one integration procedure applies to every platform.
TheGameAgent helps overseas developers prepare and coordinate Korean adult-game rating applications.
Our support can include:
We cannot guarantee a specific rating or approval date because the final decision belongs to the competent rating authority. However, a complete and consistent submission can substantially reduce preventable delays and repeated document requests.
If your game contains paid randomized rewards, you should also review Korea’s separate probability-disclosure obligations. See our Korea Probability Disclosure Compliance: 5 essential Q&As.
