Understand What an ESN Check Is
Don’t know what an ESN check is? No problem – let’s get you up to speed!
An ESN (Electronic Serial Number) check is a way of verifying the validity and status of a mobile phone. This check is important for those who plan to purchase a used phone, as it will tell you whether the device has been reported lost or stolen. Knowing this information can help protect you from buying a malfunctioning or inoperable device.
When looking into ESN basics, there are two key pieces of information that must be obtained:
1) Find out if the cell phone’s ESN number has been blacklisted
2) Determine if the device is compatible with your current wireless provider’s network service.
If either of these checks returns negative results, then the phone should not be purchased as it may be unusable.
In order to perform an ESN Validity Check one can use online tools like IMEI24 or websites such as Swappa which offer free services that will verify if a device has been blacklisted or blocked by carriers.
It’s important to understand all aspects of an ESN before making any decisions about purchasing a used phone. Doing so can ensure that you don’t experience any nasty surprises when using your new device!
Find Your Phone’s ESN Number

To discover your device’s unique electronic serial number, take a look inside. It’s like delving into a secret code, uncovering the mystery of what lies beneath. Depending on the type of phone you have, there are several places to find the ESN number.
For example, if you have an iPhone 8 or above, look for the ESN label at the bottom of the back cover; for Android devices, check in settings under “About” or “Status”. If neither of those options works for you, then try these other methods:
Method | Location/Instructions |
---|---|
SIM card tray | Look under your removable SIM card tray and can be found on both iPhones and Androids. The ESN is printed on a white sticker with bar codes. |
Battery compartment | Sometimes it can be found on either cardboard inserts within boxes (Apple devices) or printed onto plastic wrap-around packaging material (Android). This is typically only available when purchasing new phones as most users throw away their boxes after unboxing them. |
Box or packaging material | Sometimes it can be found on either cardboard inserts within boxes (Apple devices) or printed onto plastic wrap around packaging material (Android). This is typically only available when purchasing new phones as most users throw away their boxes after unboxing them. |
For older Apple models prior to iPhone 8, you may need to call customer service and ask for help with locating your device’s ESN number since some of them do not have labels anywhere visible. Additionally, many used phone providers offer free ESN lookup and verification services alongside their selection of products so searching online might yield helpful results as well!
