What is A Serial Number in Smartphones.? Why Is It Important

You must have heard about fake iPhones selling on various portals. The fake ones do not have a serial number on them. If you have a fake iPhone and you take it to the service center for some work, the support person will know that your device is fake by trying to scan the serial number.

If it’s an original device legally sold by Apple or its resellers, then it will have a serial ID. This is a unique identifier that can differentiate between real and fake. Also, it can preserve information regarding where the device was assembled or manufactured. The serial number usually is alphanumeric.

A customer can use this ID to check whether his device still has a warranty that he can claim for a service such as repairing or replacement of any iPhone part.

The serial number is unique to you and your device. It is something you should not reveal in public. I mean you can use it for authenticating on official Apple sites or with the official support guy. However, never post screenshots of your iPhone serial number in social media forums, personal chats, etc. Only when someone officially from Apple is requiring that ID to authenticate your device, then only provide them the info.

That’s why you may have seen people often blur the serial number if for some reason they are posting about it. Fraudulent people can misuse this serial number to fake the warranty on their iPhones. Then they order parts or services through that. This is very wrong. Of course, you do not want some random joe to enjoy freebies on your device’s warranty.
