Your device's serial number is a unique identifier typically found in several key locations, most commonly on the item itself, its packaging, or accompanying documentation.
Common Places to Locate a Serial Number
To find your serial number, start by thoroughly checking the physical device, its original packaging, and any included manuals or papers.
On the Device Itself
Serial numbers are normally found on a label on the item. This label can be small and may require close inspection. Specific locations vary significantly by device type:
- Laptops and Desktop Computers: Look for a sticker on the bottom or back of a laptop, or on the side or back of a desktop tower. For some laptops, it might be inside the battery compartment.
- Smartphones and Tablets: Often printed or etched on the back of the device, on the SIM card tray, or under the battery (if removable).
- Printers and Scanners: Check the back, bottom, or inside the access doors.
- Televisions and Major Appliances: The serial number is usually located on a label on the back panel, side, or inside a door or compartment (e.g., inside the refrigerator door).
- Small Electronics (Cameras, Speakers, etc.): Typically found on a sticker on the bottom, back, or a less visible surface.
Packaging and Documentation
- Original Retail Box: The serial number is frequently printed on a sticker on the outside of the product's original packaging.
- User Manuals and Guides: In some cases, serial numbers are printed in the manual or on a piece of paper that came with the item. Check the first few pages, the back cover, or a dedicated "Important Information" section.
- Warranty Cards or Registration Papers: Many products include a separate card or sheet specifically for warranty registration, which often lists the serial number.
- Purchase Receipts or Invoices: For larger electronics or software licenses, the serial number or product key might be listed on your proof of purchase.
Within Device Software (for Electronic Devices)
For many electronic devices, especially computers, smartphones, and smart devices, the serial number can also be accessed through the operating system or device settings:
- Windows PCs:
- Go to Settings > System > About.
- Alternatively, open Command Prompt (CMD) and type
wmic bios get serialnumber
then press Enter.
- macOS Computers:
- Click the Apple menu () in the top-left corner of the screen, then select About This Mac. The serial number will be displayed in the overview.
- Smartphones and Tablets (iOS/Android):
- Navigate to Settings > General > About (iOS) or Settings > About phone/device > Status or Hardware Info (Android).
