Before checking whether your IMEI or ESN is clean it’s important to know what these terms mean and what their significance is. Today we are going to teach you how to check if your IMEI or ESN is clean, blacklisted, reported as lost or stolen – works for iPhone, Samsung, LG, HTC, Sony, ZTE, Huawei, Alcatel and other brands. Read on to know all the methods.
What is an IMEI Number
The IMEI stands for International Mobile Equipment Identity. Effectively what it is a unique number that every single iPhone has which is used for identification of activation status to the carrier it belongs to. However, be aware of the fact that there is a different serial number on the device, so the IMEI number shouldn’t be confused with the actual serial number of the gadget.
What is an ESN Number
ESN is Electronic Serial Number and is basically just another name for the IMEI number. To check if your device has a clean ESN you will need the IMEI number. This may be confusing at first but everything will become much clearer soon.
What causes a bad ESN in an iPhone
There are numerous causes for this to occur:
- The iPhone was not paid off by the original owner
- The iPhone is still active on someone else’s account
- The iPhone has been reported as lost or stolen
In case you misplaced your device and reported it as lost to your carrier to claim insurance but then found the device again, you will need to let your carrier know you found the phone. If you don’t it will have a bad ESN since it has been reported as lost.
Also, it’s important to remember that if a device has a bad ESN for any of the above-mentioned reasons, then the iPhone will not be able to be activated on another customer’s carrier account.
Finding the IMEI Number on your iPhone
To check your IMEI just go to Settings -> General -> About and scroll down to IMEI or open the phone app and dial *#06#.
If you don’t want to use this method it’s also possible to see it physically located on the device as well. Here is how to determine this model by model:
- iPhone 4/4S: On the SIM card tray.
- iPhone 5/5C/5S: On the back housing of the iPhone.
- iPhone 6/6+: On the back housing of the iPhone.
- iPhone 6S/6S+: On the SIM card tray.
- iPhone 7/7+: On the SIM card tray.
- iPhone X/8/8+: On the SIM tray.
Once you have the IMEI it is time to check out the ESN number on your iPhone.
