Whether you need to register a warranty, check for recalls, or get technical support, knowing where to find your laptop’s serial number is a crucial piece of knowledge.
Check the Physical Laptop First

This label usually lists the serial number (often abbreviated as S/N or Serial No.), along with the model number and other regulatory information. If it’s not on the bottom, check inside the battery compartment after safely removing the battery. Some manufacturers also place it on the screen bezel or the main body.
Find It Through Your Operating System

On a Windows PC, open the Command Prompt and type wmic bios get serialnumber. Press Enter, and your serial number will appear.

A Quick Tip for Safe Keeping

You could save it in a password manager, email it to yourself, or write it down in a important documents folder. This simple step can save you a significant amount of hassle later on.
