For most devices, the model number (e.g. "GT-I9505" or "SM-G900F") is found inside the device. It becomes visible when you open your device and remove the battery.
As an alternative, you can also type your model name (e.g. "GALAXY S5") instead of the number. But it may be a bit more difficult to find your specific device that way.
Still not sure? Then perhaps Samsung can help you out with their model number lookup tool.
