Have you ever heard of an ESN?

It stands for Electronic Serial Number and it’s a unique code assigned to each mobile device.

If you want to clear the ESN on your phone, you’ll need to perform a factory reset followed by speaking with your carrier.

In this article, we’ll explore how to clear the ESN on your phone so you can resell or give away your device worry-free!

Clear The ESN On A Phone

Key Takeaways

  • Clearing ESN erases all data and resets the phone to factory settings.
  • Residual data may remain on the phone’s memory after a factory reset.
  • Specialized software or services can securely wipe devices before recycling or disposing of them.
  • Contact the carrier to verify that the ESN has been cleared before reselling or giving away the device.

Understand What an ESN Is

You may be wondering what an ESN is – let’s take a look and find out!

An Electronic Serial Number (ESN) is a unique numerical code assigned to each cellular device. This number is used for phone tracking, as well as determining which services, such as data or voice plans, will be available for the user.

Each time someone purchases a phone from their carrier, they are assigned an ESN that will link the device with its user account. It also helps carriers keep track of all their customers’ cellular usage.

The ESN is located inside the battery compartment of most cell phones and can typically be found on the bottom right side of the battery or on a sticker at the back of the phone. If you’re having trouble locating it, you can always contact your wireless carrier and they should be able to provide you with more information about it.

Knowing where to find your ESN can come in handy if you need to transfer information from one device to another or if you’re looking into unlocking your phone from its current network provider.

Clearing the ESN will completely erase all data stored on your mobile device and reset it back to factory settings so that it can no longer be tracked by any previous networks or accounts.

To do this effectively, make sure to delete all personal data from your phone before proceeding with clearing its ESN – otherwise, any information left behind could still be tracked by former service providers.

Perform a Factory Reset on the Device

Resetting the device to its original factory defaults will set it back to square one, like a blank slate.

This means that all of your personal data and application settings will be removed, so you should make sure that any important information is backed up prior to resetting the device. Doing this will ensure nothing is lost or forgotten during the reset process.

It is also important to note that even after performing a factory reset, some residual data may still remain on the phone’s memory. Therefore it is suggested that you use specialized software or services designed for securely wiping devices before recycling or disposing of them.

The process for performing a factory reset varies depending on the type and model of the device in question, but generally involves accessing the ‘Settings’ menu and selecting an option such as ‘Reset’ or ‘Factory Data Reset’. Once selected, you will be prompted with either additional steps or warnings about what will happen when you confirm the reset command; follow all instructions carefully in order to successfully clear your ESN number.

Contact Your Carrier for Final Steps

Contact Your Carrier for Final Steps

Once you’ve successfully performed a factory reset to clear the ESN of your phone, the next step is to contact your carrier.

Your carrier will need to verify that the ESN has been cleared in order for you to activate the new device on their network. They may also provide additional information or instructions that are necessary in order for you to get your new device up and running.

Don’t forget to contact your carrier for final steps!

Verify the ESN Clearance

Verify that the ESN is cleared by checking the phone’s settings. You’ll need to check compatibility with your carrier and verify eligibility for a new plan. This can be done by contacting your carrier directly or visiting their website.

Once you’ve verified that the ESN has been cleared, you can proceed with setting up your new phone. Make sure to double-check all of the settings before activating it, as any mistakes could cause problems down the line.

Activate the New Device on Your Network

Activate your new device on your network with ease – but look before you leap! Before activating, make sure to review the different upgrade options available to ensure that you’re getting the best coverage and data plan for your needs.

Here’s a list of things you need to consider:

  • Network Coverage:
  • Check if your current network has good reception in your area.
  • Investigate various carrier networks and compare their coverage maps.
  • Upgrade Options:
  • Research the different plans available from each carrier, such as unlimited data or a pay-as-you-go plan.
  • Compare prices between carriers and decide which option works best for you.

Once you’ve done this research, go ahead and activate the new device on your desired network! Keep track of any activation fees or additional costs that may be associated with switching providers, so there are no surprises down the line.


Clearing the ESN on your phone isn’t as difficult as it may seem. With a few simple steps, you can have your device ready to go in no time.

For example, take the case of Sally who recently experienced a glitch with her phone’s ESN number. After performing a factory reset and contacting her carrier for confirmation, she was able to get her phone up and running again in no time!

Clearing an ESN can be done quickly and easily if you know what steps to take. So don’t sweat it – just follow these instructions and clear that ESN with ease!
