How to Find Laptop Serial Number

Serial numbers may appear unremarkable at first glance. However, their significance becomes apparent when you require the serial number of your laptop or smartphone for warranty claims, manufacturer support, reporting a stolen device, or seeking theft recovery. At that point, it becomes an immense inconvenience.

Fortunately, there are various methods to locate a serial number. You can retrieve it by executing a straightforward command, examining system information, searching for physical labels, or referring to other relevant documents.

 

Find the Serial Number Using Operating System Tools

If your laptop is fully functional and you're not experiencing any login issues, the simplest method to find the serial number is from within your operating system.

Windows

You can easily fetch the serial number by running a command in Command Prompt. Here's how:

1. Type "Command Prompt" in Windows Search.
2. Right-click on the Command Prompt app and select Run as administrator.
3. Type the following command:

   wmic bios get serialnumber 

4. Press Enter. 
5. 
   
    If you are unable to view the serial number using the Command Prompt utility, you can easily locate it in the System Information. To do this, press the Win+R keys, type "msinfo32," and hit Enter. Afterward, go to the System Summary tab, where you will find the serial number listed along with other information.

1. Press Command+Space to open Spotlight search.
2. Type "Terminal" and press Enter.
3. Type the following command in Terminal:

   system_profiler SPHardwareDataType | grep "Serial Number" 

4. Press Enter.
   

 

Alternatively, click on the Apple logo in the top-left corner and click About This Mac. macOS will show you your device's serial number, among other system information. 

Similarly, if you use a Linux operating system, you can easily find the serial number of your Linux device. 

Check the Serial Number on the Physical Label 

 In case your laptop encounters a hardware problem and you require assistance from the manufacturer, you can locate the serial number by examining the physical labels.

Typically, the serial number can be found on a label on the bottom side of the laptop. Turn your laptop upside down and search for a label. Once you locate it, the serial number will be displayed there.

If you don't see a label on the underside, check if your laptop has a removable battery. If it does, remove the battery, and you'll likely find the serial number printed inside the battery compartment.
