Great to hear that you want to choose a Share the Sun project!
When you buy a WakaWaka you will find a Share the Sun sticker in the packaging. The code consists of three letters and three numbers. Example: ABC123.
If you have the WakaWaka Light, the code is put on the packaging. If you have the WakaWaka Power+ you can find the sticker inside on the left or on a loose leaflet.
On that sticker you will find your personal Share the Sun Code, which you can fill in on www.waka-waka.com/give/, there you can choose one of the three projects.
