Chromebook Serial Number

I recently saw a discussion involving a user who was trying to figure out how to determine the serial number of a chromebook when the sticker had been removed from the device. Unable to easily locate that procedure, I thought it would be a good idea to make a post to help others in this situation.  This process has only been tested on a Samsung 550 model.

If you aren’t familiar with developer mode, I’d suggest reading this article.  In most scenarios, all user data is stored in the cloud; erasing the stateful partition has no ramifications to the end user.  Please understand what you are doing by booting into developer mode before continuing with this process.

  1. Boot the device into developer mode (toggle the developer switch)
  2. At the chrome OS verification screen, press Ctrl+D (this will wipe the stateful partition)
  3. The device will erase and reboot
  4. Once again, press Ctrl+D at the chrome OS verification screen
  5. At the select language screen, press Ctrl+Alt+→ (the “forward” key, top row, F2)
  6. Type
    chronos

    and hit enter

  7. Type
    sudo dump_vpd_log --full –stdout

    and hit enter

“Product S/N” is your serial number!  Let me know if this helped you or if you have any questions in the comments.

  1. How can I run this command in JavaScript. As I need my app to fetch serial number, device id and other system information.

  2. For a Samsung ChromeBook (3-Series, ARM Exynos CPU) you invoke developer mode by holding esc-(Refresh) and pressing the power button, then hitting control-D at the recovery screen then hit enter to turn off verification.

    With the extra hyphen mentioned by Sam above, this hint works on the Series 3 as well.

    But it might be more helpful to access chronos (root) directory from the browser using Ctrl+Alt+T (while in dev mode). Terminal screen will display: crosh>. You just need to type: shell (hit enter).

    You should see: chronos@localhost / $

    Then type: sudo dump_vpd_log –full –stdout (hit enter)
