How to Find Serial Number on Windows 10 Quickly and Easily

Knowing how to find your Windows 10 serial number is essential for various reasons, such as verifying your device’s authenticity, troubleshooting issues, or preparing for warranty service. The serial number uniquely identifies your device and can be useful when contacting support or checking warranty status. This guide provides simple, step-by-step instructions to locate your serial number using built-in tools and methods on your Windows 10 computer. Before you start, ensure your device is powered on and connected to the internet if needed. No additional software is required—just your Windows 10 system.

What You’ll Need

• A Windows 10 PC or laptop
• Administrator access to your device (if using Command Prompt or PowerShell)

Step-by-Step

1. Using System Information: Press the Windows key + R to open the Run dialog box. Type msinfo32 and press Enter. The System Information window opens. Look for the System Serial Number entry—this is your device’s serial number.
2. Through Command Prompt: Click on the Start menu, type cmd, right-click on Command Prompt, and select Run as administrator. In the Command Prompt window, type wmic bios get serialnumber and press Enter. The serial number will be displayed below.
3. Using PowerShell: Search for PowerShell in the Start menu, right-click, and select Run as administrator. Type Get-WmiObject win32_bios | select SerialNumber and press Enter. The serial number appears in the output.
4. Check the Device or BIOS Sticker: If your device is a laptop or desktop, look for a sticker on the bottom, back, or inside the battery compartment. Manufacturers often print the serial number there.
5. Via Manufacturer’s Support Website: Some manufacturers allow you to retrieve serial numbers by logging into your account on their support site, especially if you registered your device. Check your manufacturer’s instructions for specific steps.

Common Mistakes

• Using the wrong method—ensure you’re using the correct tool or command for your needs.
• Not running Command Prompt or PowerShell as administrator, which can restrict access to certain system information.
• Looking for a serial number on the device itself when the device may not have a sticker or it’s worn out.
• Confusing the Windows product key with the serial number; they are different. The serial number is specific to hardware, whereas product keys relate to software licensing.

Tips

• If the command line methods do not work, try the System Information utility, as it often displays the serial number clearly.
• Keep your serial number in a safe place for future reference, especially if you plan to contact support or need warranty service.
• Some OEM devices may have serial numbers embedded in BIOS/UEFI firmware, making them accessible only through system tools.
• For laptops, the serial number is often printed on the bottom or inside the battery compartment; check these areas if software methods fail.

Troubleshooting

If you encounter issues finding your serial number:

• Command line commands do not display the serial number: Ensure you run Command Prompt or PowerShell as an administrator. Restart your computer and try again.
• The System Information tool does not show a serial number: Some systems may not store this information in BIOS. Try checking the device physically for stickers or labels.
• The serial number appears as blank or generic: This can happen on some custom-built PCs or devices with non-standard firmware. Contact the manufacturer directly for assistance.
• Unable to locate serial number via software: If hardware labels are missing or illegible, reaching out to the manufacturer with proof of purchase may be necessary for warranty claims.
