What is an IMEI, ESN, MEID and how do I find it?

In order to complete the sale of your device, it must have a clean ESN.

ESN stands for Electronic Serial Number. This number acts as an individual identifier for a mobile device, and each one will have its own specific number. ESN numbers come in a couple different formats, most notably IMEI and MEID.

IMEI stands for International Mobile Equipment Identity, MEID stands for Mobile Equipment Identifier, and both are another form of identification for a mobile device.

When someone reports to their carrier and the authorities that they have lost their phone, the ESN will be altered to indicate that information.

IF an ESN comes up as active, it is most likely because of the following reasons:

  1. The device still has a balance due with the carrier
  2. The device has been reported as lost or stolen

If our inspection team discovers that your device has an active ESN, we will not be able to buy it back. At that point, we’ll get in contact with you to go over what can be done to resolve the issue. You’ll need to notify your carrier and take the necessary steps to deactivate it.

To find your IMEI number:


  • The IMEI number is in the small engravings toward the bottom of the back of the iPhone.
  • Go to Settings > General and tap Touch IMEI/MEID and it will display your number


  • Go to Settings > About Phone > Status
  • Scroll down until you find the display for your MEID or IMEI
