Your device’s serial number is a unique code that the manufacturer gives the phone. No two serial numbers are the same. Should you need to find your phone’s, there are a few places you can look.
A serial number is usually a combination of letter and numbers. There’s no set length— the manufacturer determines that. The serial number will usually be denoted by an “S/N:” on the box, as you’ll see below. As with all things Android, the path to your serial number may have different routes, but this guide should give you a general idea of where to look.
Option One: On Your Device’s Retail Packaging
Often, the box your device came in will carry the serial number. It’s usually located on the outside of the box on a sticker that also contains several bar codes, your device’s IMEI number, etc. It’ll either be on the back or the side of the box.
Option Two: Under Your Device’s Battery
These days, most Android devices come with non-removable batteries. But if you have a device with a removable battery, you will often be able to find the serial number printed underneath.
Option Three: In Your Device’s System Settings
To find your device’s serial number in the software, go to Settings > System.
Then jump into About Phone > Status.
Your device’s serial number will generally be located toward the bottom of this screen.
If you don’t see your device’s serial number here, you may need to poke around in the About Phone section a bit more—it may be in a slightly different place depending on the manufacturer. Gotta love Android.
What is the Serial Number Used For and Should It Stay Private?
Your serial number is generally used by the manufacturer to track device inventory—mainly for things like repairs and warranty claims. Since it’s usually printed on the outside of the box, you can infer it’s not terribly important that it stays completely private. However, there are certain situations where sharing a serial number can cause you grief down the road. For example, if you share your serial number and someone uses it to file a false warranty repair on a device, you may suddenly find yourself with a phone that is out of warranty.
OEM’s generally recommend against making your device’s serial number public—it is unique to your device after all, and there’s no reason to share it. So no tweeting, please.
