Find Your Fitbit Model by Looking at the Device Itself

The fastest way to identify your Fitbit is to look at the physical device. Each model has a distinct shape, size, and display style that makes it recognizable once you know what to look for. You do not need to open any apps or check paperwork — the answer is usually in your hand.

Start by examining the overall shape. Fitbit makes several distinct form factors: some are small rectangular trackers that clip to clothing, some are wristbands that look like watches, and some are full smartwatches with large screens. The shape alone narrows down your options significantly. Next, look at the display. Some Fitbits have no screen at all — just LED lights. Others have small monochrome (black and white) screens. The newest models have color touchscreens. The combination of shape and screen type will identify most models.

Key Takeaways

  • The physical shape and display type of your Fitbit are the quickest identifiers — clip trackers, wristbands, and smartwatches are visually distinct.
  • Check the back of your device for the model name printed directly on the case or band.
  • Open the Fitbit app on your phone and look at the device settings to see the exact model name and firmware version.
  • If you have the original box or paperwork, the model name appears on the packaging and in the quick-start guide.
  • Fitbit's official support site has a visual guide showing all current and discontinued models side by side for comparison.

Check the Back of Your Fitbit for the Model Name

The model name is usually printed directly on the back of your Fitbit device. Look at the underside of the band or the rear of the tracker case. You may see text like "Fitbit Charge 5," "Fitbit Inspire 3," "Fitbit Sense 2," or "Fitbit Versa 4." This printed name is the official model identifier.

The text may be small and require good lighting to read clearly. If the back is worn or the text has faded, try wiping the surface gently with a soft, dry cloth. Some older Fitbits have the model name stamped into the material rather than printed, which can be harder to see but is still readable under the right angle and light.

Use the Fitbit App to Identify Your Device

If you cannot read the back of your device or want to confirm the model name, the Fitbit app on your phone will show you the exact model. Open the Fitbit app and tap the profile icon (usually in the bottom right corner). Select your device from the list of connected trackers.

Once you are in your device settings, look for a section labeled "About" or "Device Information." This screen displays the model name, serial number, and firmware version. The model name shown here is the official designation you can use to search for support articles, replacement bands, or accessories. If you have multiple Fitbits connected to your account, make sure you are viewing the settings for the device you want to identify.

Match Your Device to Common Fitbit Models

Fitbit currently makes several active models, and many older models are still in use. Here are the most common ones and how to recognize them:

Clip trackers (Fitbit Zip, Fitbit One) are small rectangular devices about the size of a postage stamp with a clip on the back. They have no screen or only a small LED display. Wristbands (Fitbit Inspire, Fitbit Charge series) are thin bands worn like a watch with a small rectangular screen. Smartwatches (Fitbit Sense, Fitbit Versa) are larger, square-shaped devices with a full touchscreen display. The Inspire line is the most basic and affordable. The Charge line adds more detailed fitness tracking. The Sense and Versa lines are full smartwatches with apps and voice control.

If your device looks like a traditional watch with a round face, it is likely a Fitbit Ionic or an older Fitbit model. If it is a thin band with a small screen, it is probably an Inspire or Charge. Comparing your device's shape and screen size to photos of these models online will narrow it down quickly.

Check Your Original Packaging or Documentation

If you still have the box your Fitbit came in, the model name is printed on the outside packaging. Look at the front of the box or the side panel — the model name appears prominently. The quick-start guide inside the box also lists the model name on the first page.

If you bought your Fitbit from a retailer, you may have a receipt that shows the model name. Check your email for order confirmations from the retailer or from Fitbit directly if you purchased online. These documents often include the model name in the product description.

Use Fitbit's Official Model Comparison Guide

Fitbit maintains a visual guide on its official website that shows all current and past models side by side. Visit the Fitbit support section and search for "compare Fitbit models" or "Fitbit models." This page displays photos of each model, lists the key features, and helps you match your device visually.

This approach is especially useful if you inherited a Fitbit or bought one secondhand and are not sure which version you have. The visual comparison makes it straightforward to spot the differences between similar-looking models, like distinguishing a Charge 4 from a Charge 5, or an Inspire 2 from an Inspire 3.

What to Do If You Still Cannot Identify Your Fitbit

If none of the above methods work, you can contact Fitbit support directly. Have your device serial number ready — you can find this in the Fitbit app under device settings or on the back of the device itself. Fitbit support can look up your device based on the serial number and tell you the exact model.

You can also post a clear photo of your device (front and back) in Fitbit community forums or on Reddit's Fitbit subreddit. Other users are usually quick to identify models based on appearance. Make sure the photo shows the overall shape, the screen (if any), and any visible text on the back.

Frequently Asked Questions

Can I find my Fitbit model if I do not have the device with me?

Yes. Open the Fitbit app on your phone and go to your profile settings. The app shows all devices ever connected to your account, even if they are not currently paired. The model name appears in the device information section for each one.

What if the text on the back of my Fitbit is worn off?

Use the Fitbit app method instead — open the app, go to your device settings, and look for the model name in the "About" or "Device Information" section. The app always has the correct model name stored, regardless of the condition of the physical device.

Is there a difference between Fitbit Charge 5 and Fitbit Charge 5 SE?

Yes, the SE is a variant of the Charge 5 with slightly different band options and sometimes different pricing. Both will show as "Fitbit Charge 5" or "Fitbit Charge 5 SE" in the app. The SE designation appears in the model name if you have that version.

How do I tell the difference between a Fitbit Inspire 2 and Inspire 3?

The Inspire 3 has a slightly larger screen and a color display, while the Inspire 2 has a smaller monochrome screen. The easiest way is to check the app — it will show the exact model number. Visually, the Inspire 3 screen is noticeably bigger and brighter.

Where is the serial number on my Fitbit?

The serial number is printed on the back of the device, usually below or near the model name. It is also displayed in the Fitbit app under device settings. You need the serial number if you contact Fitbit support or if you want to register your device for warranty purposes.
