How to Easily Find Your PC’s Serial Number for Warranty and Support

When you encounter issues with your PC and require assistance from the manufacturer or support services, having essential information about your computer is crucial. Among this vital information is your PC’s serial number, an indispensable piece of data for warranty claims and technical service repairs.

This information is as critical as keeping your operating system and drivers updated for the various components within your computer. By ensuring your system is up to date, you simplify the process of identifying and addressing issues when seeking warranty services due to a malfunction.

Using the Command Prompt (CMD)

While some might think finding the serial number of their PC is as easy as checking the packaging or searching for stickers on the computer’s chassis, these stickers often go missing over time. This can make it challenging to access your PC’s serial number, which may not seem significant until you face a problem and the technical service asks for this information.

Fortunately, there’s a straightforward method to retrieve your PC’s serial number, even if you lack documentation, packaging, or any other supporting materials. This process involves using the Command Prompt, and it’s relatively simple. Here’s how:

  1. Open the Command Prompt by typing “cmd” (without the quotes) into the Windows search bar.
  2. Right-click on the Command Prompt and select “Run as administrator.”
  3. In the Command Prompt window, enter one of the following commands:
    • wmic bios get serialnumber
    • wmic csproduct get identifyingnumber

After entering either of these commands, you’ll see two lines displaying “SerialNumber” and your PC’s serial number. Keep in mind that on older computers, this number may not appear in the BIOS, in which case contacting the manufacturer might be the only option to obtain the serial number.

Using Windows PowerShell

Windows PowerShell is an advanced version of the Windows command line that offers several advantages and allows you to execute a wider range of commands. You can use this tool to retrieve your computer’s serial number when needed, such as for warranty claims. Here’s how:

  1. Open Windows PowerShell by pressing the Windows + R keys, typing “PowerShell,” and hitting Enter.
  2. In the PowerShell window, enter one of the following commands:
    • Get-WmiObject win32_bios | Format-List SerialNumber
    • gwmi win32_bios | fl SerialNumber

Both of these commands yield the same result as the previous commands in the Command Prompt (CMD). Remember this method for quickly obtaining your computer’s serial number the next time you need it.
