You might be asked for your Android phone’s serial number when filing a warranty claim, getting tech support, or tracking a lost device. The number is unique to your phone and is not the same as the IMEI.
This article shows simple ways to find your device’s serial number. Even if your phone won’t turn on, there are still options available.
What Is a Serial Number and Why It Matters
The serial number is a unique ID assigned to your Android device by the manufacturer. It helps identify that specific phone or tablet among millions of others.
People often confuse this with the IMEI, but they are not the same. The IMEI is used by mobile networks, while the serial number is for hardware identification.
You’ll need the serial number when contacting support, filling out warranty forms, or managing service requests through Google, Samsung, or your mobile carrier.
Find the Serial Number in Android Settings
If your device is working, the easiest way to find the serial number is through the Settings menu.
- Open Settings
- Scroll down and tap About phone
- Look for Serial number or S/N
It may appear near the bottom of the screen or under a sub-menu like “Model” or “Status,” depending on your Android version and phone brand.
Check the Original Box, Receipt, or Sticker
If your phone is powered off, broken, or lost, you can still find the serial number through original packaging or documents.
Here’s where to look:
- The side or bottom of the phone’s original box
- The receipt or invoice from your purchase
- A warranty card or printed documentation from your carrier
- A label or sticker on the back of older devices or under the battery (for removable-battery models)
Use ADB Command via USB (Advanced)
This method is for advanced users who have USB debugging enabled on their device before it went offline.
If your phone is connected to a computer and ADB is installed, run this command in the terminal or command prompt:
adb get-serialno
It will return the serial number of the connected Android device. This works best when the phone is unlocked and authorized with the PC.
Can You Find It If the Device Won’t Turn On?
Yes. You can check the original packaging, Google account, or contact your carrier if the device won’t boot. Some Google Pixel and Samsung devices may also show the serial number in your Google account dashboard or support page.
