The Nintendo 3DS utilizes a similar title-based organization as seen in the Wii and DSi platforms. The same update server is being used as was with the DSi, however a new common key has been introduced.

The organization of Title IDs has not been documented fully yet.

Here are some confirmed Title IDs (from the first update):
