Finding Your MAC Address

If you have purchased, or are about to purchase, a Node-Locked license for Particle Flocker, you will need to provide your MAC address before a license can be generated for your computer.

A MAC address is a unique identifier which almost all computers will have built into their hardware. Depending on your operating system the way you find the MAC address will differ:

  1. Windows
  2. Linux

Windows x64

There are a couple of ways you can find your MAC address on a Windows PC:

Option 1: Download “Find My MAC!” Helper

We like to make your life as easy as possible and that’s why we have created a simple utility called Find My MAC which displays your computer’s MAC address on screen for you to copy and paste into the purchase form.

Simply download and run the utility by clicking the button below:

Download "Find My MAC" Helper

You will require Microsoft .NET Framework 4.5 to be installed on your PC to use the Find My MAC helper.

Option 2: Manually Find Your MAC Address

If you’d rather find your MAC address manually, simply follow the instructions below:

  1. Click on the Windows menu or press the Windows Start Key and run:

  2. A window with a black background should appear. Type the following in to that window:
    ipconfig /all
  3. Look for a line that says Physical Address and then six pairs of characters separated by dashes (e.g. 2E-1A-1F-AA-4A-25). This is the MAC address.
    There may be more than one Physical Address in the list. If that’s the case, you should always use the first one!


  1. Open a terminal window and type

    Note: If you see an error message to the effect of “permission denied”, then instead type:

     su -c "/sbin/ifconfig"

    You may then be prompted for the password for the “root” user.

  2. You should see a network adapter listing that is similar to the example below, with adapter device names in the leftmost column. Most Linux distributions call the first Ethernet network adapter eth0, and subsequent adapters eth1, eth2, etc. You will find the hardware address listed after HWaddr. The loopback adapter, lo, can be ignored because it is not a physical network device.
    IMPORTANTThere may be more than one MAC address in the list. If that’s the case, you should always use the first one!
