That little sticker on the bottom of your laptop holds a key piece of information: the serial number. It might seem like just a random string of letters and numbers, but knowing how to find it is incredibly useful. Whether you need to register your device for warranty support, check for compatible parts, or file an insurance claim, your laptop’s serial number is its unique identifier.
Finding Your Serial Number on the Physical Laptop
The most straightforward place to look is on the laptop itself. Gently turn your laptop over and look for a sticker or etched label. It’s often near the battery compartment or on the bottom casing. The serial number (sometimes abbreviated as S/N or Serial No.) will be listed there. If you have a removable battery, you might also find the serial number on a sticker inside the battery bay. This method is perfect if your laptop won’t turn on.
Using Your Computer’s System Information
If your laptop is operational, you can find the serial number digitally in just a few clicks. On a Windows PC, press the Windows key + R, type cmd to open the Command Prompt, and then type wmic bios get serialnumber and press Enter. The number that appears is your serial number. For those who prefer a graphical interface, you can also press the Windows key + R, type msinfo32, and look for the System SKU or System Serial Number in the System Information window.
Locating the Serial Number on a Mac
Apple makes this process just as simple. Click the Apple menu in the top-left corner of your screen and select About This Mac. In the window that appears, you’ll see your computer’s serial number clearly listed. You can click on the serial number text to copy it directly to your clipboard for easy pasting elsewhere.
Why Your Laptop’s Serial Number Matters

It’s essential for claiming your manufacturer’s warranty and getting technical support, as it helps the support team identify your exact model and configuration. If your laptop is ever lost or stolen, you will need the serial number to report it to the authorities. It also helps when you’re looking for specific drivers or hardware upgrades, ensuring you get the right parts for your machine.
Taking a moment to locate and safely record your laptop’s serial number is a small step that can save you a significant amount of time and hassle later. It’s the simplest way to prove ownership and get the right help for your device.
