Where to find your Chromebook's serial number

Your Chromebook's serial number is printed on a white sticker on the bottom of the device. Flip the Chromebook over, look near the center or edges of the base, and you will see a label with "Serial Number:" followed by a string of letters and numbers. Write it down or take a photo — you will need it if you contact support, file a warranty claim, or track the device for your school or workplace.

If the sticker is worn or missing, you can find the same number in your Chromebook's settings. This method works even if the physical label is no longer readable.

Key Takeaways

  • The serial number is printed on a white sticker on the bottom of your Chromebook, usually near the center or edges.
  • You can also find the serial number in Settings by going to About Chrome OS and looking for "Serial Number" in the device information section.
  • Keep your serial number handy for warranty claims, support requests, or device tracking through your school or employer.
  • The serial number is different from your device model number, which appears on the same sticker but identifies the type of Chromebook rather than your specific unit.

Finding the serial number through Chromebook settings

Open the Settings app by clicking the time in the bottom right corner of your screen, then select the gear icon. In the left menu, click "About Chrome OS." The page that opens will display your device information, including the serial number listed under "Serial Number."

This method is useful if you cannot read the sticker on the bottom of your device or if you are troubleshooting a problem and need to copy the number quickly. The serial number shown in settings is always the same as the one on the physical sticker.

Serial number versus model number

The sticker on the bottom of your Chromebook shows both a serial number and a model number, and they are different things. The model number identifies the type of Chromebook — for example, "ASUS Chromebook C434" or "Lenovo ThinkPad C13 Yoga." The serial number is unique to your individual device, like a fingerprint.

When you contact support or file a warranty claim, provide the serial number, not the model number. The model number tells the technician what kind of device you have; the serial number tells them which specific unit you own.

Why you need your serial number

Schools and workplaces use serial numbers to track Chromebooks assigned to students or employees. If your device is lost or stolen, the serial number helps identify it. Manufacturers also use the serial number to check warranty status — if your Chromebook is still under warranty, the serial number is how they confirm you are covered.

If you contact Google support or your device manufacturer with a technical problem, they will ask for the serial number to pull up your device's history and any previous repairs or issues. Keeping a record of your serial number in a safe place makes these interactions faster.

What to do if the sticker is damaged or missing

If the sticker on the bottom of your Chromebook is worn, faded, or missing entirely, the Settings method is your best option. The serial number stored in your Chromebook's system is always readable, even if the physical label is gone.

If you need to prove ownership of a Chromebook that was assigned to you by a school or employer, ask them for a copy of the assignment record — they keep their own list of serial numbers tied to each user. This is especially important if you are returning the device or if there is a dispute about who owns it.

Keeping your serial number safe

Write down your Chromebook's serial number and store it somewhere you can find it later — a notes app, a document, or even a photo in your phone. If your device is lost, stolen, or needs warranty service, you will have the number without needing to access the Chromebook itself.

If your Chromebook is school-issued or work-issued, your school or employer already has the serial number on file. You do not need to keep your own copy for their purposes, but having one for yourself makes it easier to report a problem or request support without waiting for them to look it up.

Frequently Asked Questions

Is the serial number the same as the device ID?

No. The serial number is printed on the sticker and shown in Settings. The device ID is a different code used internally by Chrome OS. For support and warranty purposes, always use the serial number, not the device ID.

Can I find the serial number if my Chromebook won't turn on?

Yes — flip the device over and read the sticker on the bottom. The physical label does not require power. If the sticker is unreadable, you will need to power on the Chromebook to access Settings.

What if two Chromebooks have the same model number?

That is normal. Many people own the same model of Chromebook. The serial number is what makes each one unique. Two identical Chromebooks will have the same model number but different serial numbers.

Do I need the serial number to sign into my Chromebook?

No. You sign in with your Google account or school account, not with the serial number. The serial number is only needed for support, warranty claims, or device tracking by your school or employer.
