Smartphone / Tablet
For Lenovo smartphones and tablets, the serial number is either on the exterior or in the settings. On Lenovo tablets, it’s usually on a label on the back. For smartphones, it’s in the SIM card tray or inside the battery compartment. You can also check Settings > About Phone/Tablet > Status for the serial number.

Look Up Serial Number via Command Prompt
If you can’t find the serial number physically, you can use the Command Prompt. A simple command will show the serial number from the BIOS on your Lenovo device. This method gives the hardware ID directly from the system, useful for warranty checks, troubleshooting, or support.
