To find out what kind of Fitbit you have, the quickest method is to check the Fitbit app if your device is paired and syncing. Open the app, tap your profile avatar in the top-left corner of the Today tab, and the full model name will appear next to the device icon in your device list.
What kind of Fitbit do I have? Check the Fitbit app first
The fastest method to identify your Fitbit model is by using the Fitbit app on your iOS or Android phone. Open the Fitbit app and tap your profile picture or avatar in the top-left corner of the Today tab. You will see a list of your paired devices, and the name shown next to each device icon is your Fitbit model, for example, "Fitbit Versa 4" or "Fitbit Charge 6". Tapping on a device in the app provides more detailed device information, including the model name and serial number. This is the easiest way to get the exact name for Fitbit support and ownership help, such as finding compatible accessories or troubleshooting issues.
Look for the model number on the back of your Fitbit
If you don't have the app available or your device isn't paired, you can check the device itself for markings. Most Fitbit trackers have the model name or number printed or engraved on the back of the physical device. The text is often small and may require good lighting to read. The model number often appears as an "FB" code (e.g., FB417, FB512) on the back of the device or near the charging pins. It may be under the band clasp and require removing the band to read. The serial number on the back of the device, a string starting with letters like "FB" followed by numbers, can also be used to look up the exact model on Fitbit's support website. The serial number is a string starting with letters like "FB" followed by numbers.
Identify your Fitbit by its design and charger
If physical markings are worn off, you can compare your device's appearance, screen type, and band attachment style to official product photos from Fitbit support pages. Different Fitbit families have unique silhouettes, band styles, and display designs that aid in visual identification. Slim trackers include Charge, Inspire, Luxe, and Alta models; smartwatches include Versa, Sense, and Ionic; and clip-on models like Zip, One, and Flex have unique shapes. The type of charger your Fitbit uses can also be a clue, as charger styles differ between models. You can also identify your Fitbit by its built-in features. Features such as heart rate, ECG, GPS, and SpO2 can help narrow down possible models, only higher-end Fitbit models support SpO2 readings or ECG (e.g., Sense, Versa 3/4, Charge 5/6). Remember, changing the wristband on your Fitbit does not change its model; the tracker unit itself determines the model.
Other ways to find your Fitbit model
If you still have the original packaging, the model name is clearly printed on the front and sides of the box. For older Fitbit models without a screen, such as the Fitbit Flex or Fitbit Zip, the model name or number may be written on the packaging or included documentation. For some powered-on and paired Fitbits, you can find the model number by navigating to Settings > About device name > Regulatory info on the device itself. If the app shows only a general name for an older device, re-pairing the device or checking Bluetooth information can often reveal the specific model. As a last resort, if the device still powers on, your phone may display its specific model name (e.g., Versa 2, Charge 4) in Bluetooth device information during pairing. If all other methods fail, you can contact the Fitbit customer service team via phone or online chat for assistance in identifying your device. Discontinued Fitbit models still function but will not receive new features or security patches, and while many older Fitbit models still sync with the current app, certain app features may not be available for older hardware.
Frequently Asked Questions
Can I identify my Fitbit without the app?
Yes. You can check the laser-etched model number on the back of the device, look at the original packaging, compare its design to official photos, or check your phone's Bluetooth pairing info.
What if the engraving on the back is worn off?
If the markings are unreadable, compare your device's silhouette, screen type, band attachment, and charger style to official product images. The charger type alone can narrow down the model family.
Will changing the band change my Fitbit model?
No. The band is an accessory and does not change the Fitbit model; the tracker unit itself determines the model.
Why does my app show a generic name instead of the specific model?
For some older devices, the app may show a general name. Re-pairing the device or checking Bluetooth information on your phone can often reveal the specific model, such as Versa 2 or Charge 4.
Can I use the serial number to find my model?
Yes. The serial number, typically starting with "FB" followed by numbers, can be entered on Fitbit's support website to look up the exact model.
