The Serial Number (SN) is a unique identifier assigned to your Narwal device.
You can easily locate the Serial Number (SN) of your device via the Narwal Freo App. Navigate to the Device homepage within the app, then tap on 'Setting', and you'll find the SN listed there. Click the icon next to the SN to copy the number.
You can also find the Serial Number (SN) on the back of the robot. Typically, the SN on the robot begins with the letter "Y" and consists of 19 digits.
