How Can I Tell Which Fitbit I Have?

Do you want to sell your Fitbit or research what it can and cannot do but don’t know what model you have? How can you tell which one you have?

To tell which Fitbit you have, you can download the Fitbit App and connect your watch. Secondly, you can visit the Fitbit website and look at the pictures for each model and identify which one you have. Thirdly, you can locate the model number on your device and search it in your browser.

Depending on your situation and why you need the model number, you might have to find it with a different method than someone else would have. We will look at all the ways you can use to find your Fitbit model quickly and easily.

Download The Fitbit App To Find Your Model

The number one way to find the model of a Fitbit is by viewing it on the Fitbit app. You cannot go wrong with this method, as the Fitbit watch connects to the app through your phone via Bluetooth. 

Here are the steps to follow to find your model type:

  1. Download the Fitbit app through the app store on your phone.
  2. Ensure your device is in range with a minimum battery life of 50%.
  3. You will have to create an account with Fitbit, or you can log in if you already have one.
  4. Go to the profile picture section on the app and choose the option “set up a device.”
  5. This setting will queue you to enable your phone’s Bluetooth setting. 
  6. While your phone is scanning, the device’s name will come up for you to connect.
  7. Here, you will see your device’s name or on your app under the account settings if it is already connected.

Visit Fitbit’s Website To Find  Your Watch

Another sure way to find your model Fitbit is to visit the main website. Your phone might not be compatible with the Fitbit app, which is fine. This method will work better for you then. You can visit the Fitbit website via this link, and you will be able to browse different photos of all the types and models available. There, you can select your device’s image and get all the info on it.

Take note that you will not be able to find the Fitbit models discontinued on this page. Thus, you will have to use one of the other methods to identify the device’s type and name.

Use The Model Number To Find Your Fitbit Device Name 

What if you have the device in working condition but don’t know which Fitbit you have? Then you can use your device to identify the model number. Follow these easy steps:

  1. Press the button to wake up your Fitbit device.
  2. Toggle or swipe to the settings option on your device.
  3. Scroll through the option until you reach the “about” tab.
  4. Under the “about” option, scroll to the regulatory info on your screen.
  5. When you click on “regulatory info,” you will see a few codes that might not make sense. 
  6. Take a look at the FCC ID displayed. The last few digits will start with “FB,” followed by a number.
  7. Go to your internet search bar and enter this FB number. The result will give you the name of your device.
