Serial number
Microbeast
If you still have the original box your Microbeast unit came in then your device's serial number is located under the barcode on the foreside of the box.
The text starts with "Serial Nr.", the subsequent 24 characters (0-9, A-F) are the serial number (in the example above 000000000000000000000000).
