How to Find Serial Number of Windows PC
Sometimes abbreviated as Serial No., SN or S/N, a serial number is a unique number assigned to the PC by the OEM (Original Equipment Manufacturer) used for identification and inventory purposes. A serial number allows the manufacturer to identify a product and get additional information about it, for replacement, or as a means of finding compatible parts.

On others, you’ll see the number printed directly on the metal or plastic. If your laptop has a removable battery, the serial number is sometimes on a sticker inside the battery compartment, under the battery.
- If you have a desktop, look at the back, top, side, or inside of the case for a manufacturer sticker.
If you can’t find the serial number on the PC itself, look online for instructions specific to your PC's model number. The manufacturer’s website should tell you exactly where to look.
- If you still have the original product box, the serial number is usually printed on it. Often on the same sticker with the bar code.
- If you purchased the PC online or in a store, the serial number may be printed on the physical or email receipt.
