Your Fitbit serial number is a unique identifier used for registration, warranty claims, and customer support. You can find it physically on the device, in the Fitbit app for some models, or on the original packaging, though the exact location depends on your specific model.
Where to find your Fitbit serial number on the device
For most Fitbit devices, Google’s help pages say to remove the top band from the device to see the serial number. On some trackers, another help page says to remove the bottom band; the serial number is located inside the device near where the band connects. On some models, the serial number may be on the charging cable, not just the device body.
For Fitbit Ace LTE specifically:
- Press and hold the top button on the watch.
- Scroll down and tap Settings.
- Tap System > About.
- Swipe down to find the serial numbers.
On the physical Ace LTE watch, you can also remove the band from the top bar; the serial numbers are etched inside the top band bar.
How to find the serial number in the Fitbit app
For Fitbit Ace LTE, open the Fitbit Ace app, tap your child’s card, tap Settings, then tap Device. The serial number appears at the bottom of the list, and tapping it copies the number. The Fitbit desktop application does not provide a direct option to view the serial number.
Finding the serial number on the original packaging
If you still have the original box, the serial number is typically printed on it, though official documentation is limited.
What to do if you still can't find the serial number
If you cannot find the serial number on the device, in the app, or on the packaging, contact Fitbit customer support. The retrieved official pages do not document a fallback process beyond the device and app instructions gathered here, so support is your best option for Fitbit support and ownership help.
