How to Find Your Laptop’s Serial Number

You can find your laptop’s serial number using various methods, depending on the make and model of your laptop. Here are some common ways to locate the serial number:

  1. Physical Sticker on the Laptop: Many laptops have a sticker on the bottom or back that displays the serial number. Look for a label that may also include other information like the model number, product key, or barcode.
  2. System Information or BIOS/UEFI: On Windows:
    • Press Win + R to open the Run dialog.
    • Type “msinfo32” and press Enter.
    • In the System Information window, look for the “System Model” or “Serial Number” field.

    On macOS:

    • Click on the Apple menu () in the top-left corner.
    • Select “About This Mac.”
    • In the window that appears, click on the “System Report” button.
    • Under the “Hardware” section, you’ll find the serial number.
  3. Laptop Box or Documentation: The original box your laptop came in may have a label with the serial number. Additionally, any documentation or manuals that came with your laptop may also include the serial number.
  4. BIOS/UEFI Menu During Boot: Some laptops display the serial number during the system startup process. This may involve pressing a specific key (e.g., F2, F12, Del) during boot to access the BIOS/UEFI menu. Look for a “System Information” or “Main” section in the BIOS/UEFI menu.
  5. Online Account or Manufacturer’s Website: If you have registered your laptop with the manufacturer or created an online account, you may be able to find the serial number by logging into your account on the manufacturer’s website.
  6. Command Prompt or Terminal: On Windows:
    • Press Win + R to open the Run dialog.
    • Type “cmd” and press Enter to open the Command Prompt.
    • Type “wmic bios get serialnumber” and press Enter.

    On macOS:

    • Open the Terminal from Applications > Utilities.
    • Type “ioreg -l | grep IOPlatformSerialNumber” and press Enter.

Remember that the location of the serial number can vary based on the laptop’s manufacturer and model. If none of the above methods work, refer to your laptop’s user manual or the manufacturer’s support website for specific instructions on locating the serial number.
