How to know which Fitbit you have

It's easy to mix up some of the company's top wearables.

Published onMarch 29, 2024

One of the top brands in the wearables landscape, Fitbit has plenty of products on shelves (and strapped to users’ wrists). For better or worse, some of the company’s fitness trackers and smartwatches look very similar. If you have a Fitbit device in hand but aren’t sure what it is, we’re here to help. Review the options below to find out which Fitbit you have.


If you haven't yet paired your wearable, locate its model number to determine which Fitbit device you have. If your Fitbit is powered on and paired, you can easily find out which device it is in the Fitbit app.

Whether you have the latest Fitbit Charge 6 in hand or one of the company’s older offerings, we have you covered. Eliminating the obvious solution that you still have your device packaging, the easiest way to identify an unpaired Fitbit device is via its model number. Some Fitbits have this code listed on the back of the fitness tracker. If yours does not, use the images below to find out which Fitbit you have on your hands.

How to identify a paired Fitbit

With so many similar products available, it can be hard to remember exactly which device you own. Fortunately, identifying your device is a common Fitbit problem that’s easy to solve. If your Fitbit and smartphone are already paired, identifying your Fitbit is even easier. Simply open the Fitbit app and tap on your profile image. You will see your device listed below your name.


The easiest way to determine whether you have a Fitbit Versa 4 or Versa 3 is by the physical button. The older model has a capacitive groove rather than a raised button.

In the latest generations, the Sense and Versa lines remain very similar, with a few health sensors dropped to cut costs on the cheaper model. Design-wise, the devices are hard to tell apart. 

If you can turn your Fitbit on and it has already been paired to a smartphone, go to Settings>About device name>Regulatory info and scroll down to find your model number.
