How to Find Your Laptop’s Serial Number: A Step-by-Step Guide

I can bet you don’t know your laptop’s serial number, even though you use it every day. Knowing it may seem unnecessary for now, but it can be very helpful at times. So, in this article, let’s learn how to find your laptop’s serial number in a step-wise process.  

Why Do You Need Your Laptop’s Serial Number?

Before learning the steps, let’s quickly understand why knowing your laptop’s serial number is important. Your laptop’s serial number is like its unique identification code. It’s not just random numbers and letters; it’s your laptop’s digital fingerprint. This number can be helpful for warranty claims, tech support, or even when selling your laptop. 

Different Ways to Find Your Laptop’s Serial Number

How to Find Your Laptop's Serial Number

Here are a few ways you can definitely try to find out your laptop’s serial number. 

1. Flip and Inspect

Flip your laptop over and inspect the back panel. Manufacturers often place stickers there. Your laptop’s serial number might be hanging out there, too. Look for a combination of numbers and letters usually labelled as “Serial Number” or “S/N.”

2. Check Under The Battery 

If you’re not lucky with the back panel, don’t worry; you have something else. Some laptops tuck the serial number under the battery. Power off your laptop, unplug it and remove the battery carefully. Check the space beneath the battery – your serial number might be hiding there.

3. Look in Your BIOS

  • First, start up your laptop and enter the BIOS settings by pressing the designated key (often F2, F10, or Delete) during boot-up. 
  • Once in the BIOS, navigate through the menus – look for a section that displays system information. 
  • And there, you’ll find your laptop’s serial number proudly on display.

4. Using Command Prompt 

This is another useful trick you can use to find your laptop’s serial number. 

  • Open the Command Prompt on your laptop by searching “cmd” in the Start menu. 
  • Type in the command “wmic bios get serial number” and hit Enter. 
  • Your laptop’s serial number should appear on the screen.

5. Check the Original Packaging

Do you remember the excitement when you unboxed your laptop? Well, that box can be very helpful at times like this. Check the original packaging – manufacturers often print the serial number on the box. 

Wrapping Up 

So, have you found it yet? Finding your laptop’s serial number might seem difficult at first, but trust me, if you follow these methods, it’ll be in your hands in no time. So, I hope this guide will help you in your journey of revealing your serial number. 


1: Can I find my serial number in the laptop’s settings?

Yes. While the method varies depending on the operating system, you can often find the serial number in the “About” section of your laptop’s settings.

2: Is the serial number the same as the model number?

No, they’re different. The model number identifies the specific laptop model, while the serial number is unique to your device.

3: What if the serial number sticker is damaged or illegible?

If your serial number sticker is damaged, don’t panic. You can still find the serial number through the BIOS or Command Prompt methods mentioned in this guide.

4: Can I find the serial number for a laptop I no longer possess?

If you registered your laptop with the manufacturer, they might have your serial number on record. Reach out to their support for assistance.
