What Is a Serial Number and Why Is It Important?




A serial number is a unique identifier for your computer that is usually assigned by the manufacturer. It can be a combination of letters, numbers, or symbols that distinguishes your computer from others of the same model. A serial number can be stored in different places, such as on a sticker on the hardware, on the packaging or documentation, or in the BIOS or UEFI firmware.


A serial number is a unique identifier for your computer




A serial number can help you identify your computer when you need to troubleshoot problems, update drivers, or install software. It can also help you verify that your computer is authentic and not a counterfeit or stolen one. For example, if you buy a computer online, you can check the serial number with the seller or the manufacturer to make sure it matches the product description and specifications.


A serial number can help you with warranty, support, and security issues




A serial number can also help you access warranty, support, and security services from your manufacturer or vendor. For instance, if you need to repair or replace your computer under warranty, you may need to provide your serial number as proof of purchase and ownership. Similarly, if you need technical support or customer service for your computer, you may need to provide your serial number as part of the registration or verification process. Moreover, if your computer gets lost or stolen, you can use your serial number to report it to the authorities or track it down using online tools.


How to Find Your Serial Number in Windows 10




There are several ways to find your serial number in Windows 10. Here are some of the most common methods:


Use the WMIC command in Command Prompt or PowerShell




One of the easiest ways to find your serial number is to use the Windows Management Instrumentation Command-line (WMIC) tool. This tool can pull the serial number from the BIOS or UEFI firmware if it's stored there by the manufacturer. To use this method, follow these steps:


  • Open Command Prompt or PowerShell by right-clicking the Start button and selecting "Command Prompt", "PowerShell", or "Windows Terminal".



  • Type the following command and press Enter: wmic bios get serialnumber



  • You'll see your computer's serial number displayed beneath the text "SerialNumber".



If this method doesn't work for you, it may mean that your manufacturer didn't save the serial number in the BIOS or UEFI firmware. In that case, you'll see something like "0", "To be filled by O.E.M.", or blank space instead of an actual serial number.


Check the BIOS or UEFI settings screen




Another way to find your serial number is to check the BIOS or UEFI settings screen. This screen contains various information about your system configuration and hardware components. To access this screen, follow these steps:


  • Restart your computer and press the appropriate key to enter the BIOS or UEFI settings screen. The key may vary depending on your manufacturer and model, but it's usually one of these: F1, F2, F10, F12, Esc, Del.



  • Look for a "Serial Number" field somewhere on a system information screen. It may be in a different place on different computers, but you can usually find it somewhere on the "Main" or "System" screen.



  • Note down your serial number and exit the BIOS or UEFI settings screen.



If this method doesn't work for you either, it may mean that your manufacturer didn't store the serial number in the BIOS or UEFI firmware at all.


Look for the serial number on the hardware, box, or elsewhere




The last resort to find your serial number is to look for it on the physical hardware itself, on the original packaging or documentation, or on some other places where it may be printed or attached. Here are some examples:


  • If you have a laptop, flip it over and look for a sticker with a barcode and a series of numbers and letters. This may be your serial number.



  • If you have a desktop PC, look for a sticker on the back, side, top, or bottom of the case. This may also be your serial number.



  • If you have an all-in-one PC or a tablet PC, look for a sticker on the back or edge of the device. This may also be your serial number.



  • If you still have the original box that came with your computer when you bought it new, look for a label with a barcode and some numbers and letters. This may also be your serial number.



If you still have any documentation that came with your computer when you bought it new
