Title ID and Unique ID Overview

Title ID

The Title ID is an ID created by adding a Unique ID to the application type and other kinds of information. The Title ID format might change depending on various circumstances on the system side, so only use the value returned by the API, and do not hard-code this value for use in save data or title paths.

You only need to enter the Unique ID in the application configuration tools, but you must enter the Title ID to specify the application to launch in the System Config Tool and cafediscrun.

Unique ID

The Unique ID is an ID that is unique to each application. Note that each different version of the same application customized for a specific region—such as Japan, the Americas, and Europe or Australia—will each have a different ID value.

Getting the Unique ID and the Product Code

Use PDM to get the Unique ID and product code for a game application.

Nintendo provides three different Unique ID values, assuming one for each regional version of an application. Contact your local Nintendo developer support group if you intend to make one version of an application for use in all regions.

Unique ID for Development

The memory region from 0xF7C00 to 0xF7FFF is allocated as a reserved region for the unique ID that will only be used during development. Use this space when you want to use a temporary unique ID during local development.

Requesting a Title ID

Title IDs are currently made up of 16 characters (64-bits) as below, with the xx, yyyyy, and zz portions as shown in the following table.
