Find Your Fitbit Model by Looking at the Device Itself
The fastest way to identify your Fitbit is to look at the physical device. Most Fitbits have a model name printed on the back or underside of the band. Turn the device over, remove it from the wristband if possible, and look for text that says "Fitbit" followed by the model name — such as Charge 6, Inspire 3, Sense 2, or Versa 4. The text is usually small and printed in black or white depending on the band color.
If you cannot find text on the device itself, check the wristband. Some Fitbit models have the name stamped or printed on the inside of the band material. Look along the inner edge where the band meets your skin. You may need good lighting or a magnifying glass to read small print.
The shape and size of your device can also help narrow it down. Fitbit makes several distinct form factors: clip-on trackers (Zip), small rectangular screens (Inspire, Ace), larger rectangular screens (Charge), round watch faces (Sense, Versa), and band-style trackers (Flex). If you remember roughly what your device looks like, you can compare it to images on the Fitbit website to confirm the model.
Key Takeaways
- The model name is usually printed on the back or underside of your Fitbit device in small text.
- Check the inside of the wristband if the back of the device is blank.
- The Fitbit app on your phone will show your device model in the settings menu under your profile.
- Your original purchase receipt, box, or warranty card lists the exact model you bought.
- Fitbit's website has a visual guide showing all current and older models side by side for comparison.
Check the Fitbit App on Your Phone
If you have the Fitbit app installed on your phone and your device is synced, the app will tell you the model name. Open the Fitbit app and tap the profile icon (usually in the bottom right corner). Select your device name at the top of the screen. The app will display your device model, firmware version, and battery status on this page.
This method works only if you have already set up your Fitbit with the app and your phone and device are connected. If you have never synced your Fitbit or you no longer have the app installed, you will need to use one of the other methods instead.
Look at Your Purchase Receipt or Original Box
Your original Fitbit box, receipt, or warranty card will list the exact model you purchased. If you still have the box, the model name is printed on the front, back, and inside. The receipt from your retailer will also show the product name and model number if you bought it in a store or online.
If you bought your Fitbit years ago and no longer have the box or receipt, check your email for an order confirmation from the retailer. Amazon, Best Buy, Target, and other major retailers send order confirmations that include the product name and model. Search your email for "Fitbit" or the retailer name to find the confirmation.
Use Fitbit's Official Model Comparison Guide
Fitbit publishes a visual guide on its website showing all current and discontinued models. Visit the Fitbit support page and look for the section titled "Which Fitbit device do I have?" or search for "Fitbit model comparison." The guide displays photos of each model from multiple angles so you can match your device to the pictures.
This method is helpful if you are not sure whether your device is a Charge 5 or Charge 6, or whether you have an Inspire 2 or Inspire 3. The photos show the differences in screen size, band style, and button placement that distinguish similar models from each other.
Check Your Device's Settings Menu
Some Fitbit models display device information directly on the tracker itself. On devices with a screen, swipe down or navigate to the Settings menu. Look for an option called "About," "Device Info," or "Settings." The model name and firmware version should appear on this screen.
Not all Fitbit models have this feature — older trackers and clip-on models do not have screens, so they cannot display this information. If your device has no screen or the Settings menu does not show device information, use one of the other methods listed above.
Contact Fitbit Support if You Still Cannot Identify Your Device
If you have tried all the methods above and still cannot identify your model, Fitbit's customer support team can help. Visit the Fitbit support website and start a chat or submit a question. You can describe what your device looks like, provide the serial number (usually on the back or inside the band), or upload a photo. Support staff will tell you the exact model.
You will need to provide some information to help them identify it — the color, approximate size, whether it has a screen, and when you purchased it. Having a photo of the device ready will speed up the process.
Why Knowing Your Model Matters
Identifying your Fitbit model is important because different models have different features, battery life, and compatibility with bands and accessories. Knowing your model helps you find the correct replacement band, troubleshoot problems specific to your device, and understand what features your tracker can and cannot do.
Each Fitbit model also receives software updates at different times, and some older models no longer receive updates at all. Knowing your model tells you whether your device will continue to work with the latest version of the Fitbit app and whether new features will be available to you.
Frequently Asked Questions
What if my Fitbit has no visible model name printed on it?
Check the inside of the wristband, the back of the device under different lighting, and the Fitbit app if it is synced to your phone. If none of these show a model name, contact Fitbit support with a photo and description of your device. They can identify it by serial number or appearance.
Can I tell the difference between a Fitbit Charge 5 and Charge 6 just by looking?
The Charge 6 has a larger screen and a physical button on the side, while the Charge 5 has a smaller screen and uses touch controls. The Charge 6 also has a slightly different band attachment system. Comparing your device to photos on Fitbit's website will show you which one you have.
Does the serial number tell me what model I have?
The serial number identifies your specific device but does not directly tell you the model name. However, Fitbit support can use the serial number to look up your device model in their system. The serial number is usually printed on the back of the device or inside the band.
What if I bought my Fitbit used and do not have the original box?
Look at the device itself for printed text, check the Fitbit app if it is synced, or compare your device to photos on Fitbit's website. If the previous owner set up the device with their account, you will need to factory reset it and set it up with your own account before the app will show the model information.
Can I find my model number online if I know when I bought it?
If you bought your Fitbit from an online retailer like Amazon or Best Buy, log into your account and find the order in your purchase history. The order confirmation will show the product name and model. If you bought it in a store, you can contact the retailer with your receipt date and payment method to look up the transaction.
