Utilize ‘Pre-registration’ as a marketing strategy before the official launch of an app. Pre-registrations allow users to learn about the app beforehand and easily access it upon release through notifications and automatic installation.

To make the most of pre-registrations, promote them across various marketing channels and consider offering exclusive rewards. This strategy can significantly boost app awareness and anticipation.

If you have any questions about pre-registrations, please contact us through 'Developer Center > Help'.

Being featured in ONE store's ‘Pre-registration PLUS’ can further enhance your visibility to a broader audience and provide additional rewards, potentially maximizing early performance.

Preparing for pre-registration

Please check the following considerations before pre-registration:

  • The package name of the app to be released is required.

    • “Register App” must be completed to enter pre-registration information. Entering the package name is mandatory during registration and cannot be changed afterward.

The official App planned to be released must be identical with the pre-registered App (Package Name/AID). If a new App is developed and released, integration with pre-registration information will be unavailable.

  • Beta apps are ineligible for pre-registration.

    • Pre-registration is not supported, if 'Service classification' is set to beta during app registration.
