When activating a new device yourself, you will be asked for the ESN, IMEI, or MEID of the device. This is simply the serial number used by your carrier to uniquely identify your device. If you don't know where to find it, you've come to the right place. There are several places to look. Some of these places will depend on the type of device you're using.
The first place to look, no matter what
type of device you have, is on the package it came in. Most boxes
feature the serial number prominently, because a lot of retail stores
try to scan in the serial number when you purchase the device. Of
course, if you threw away the packaging or have a used or refurbished
device, this might not be an option.
Under the Battery
If your device is a
phone, WiFi Hotspot, or one of the few tablets with an accessible
battery, try looking around or under the battery.
- Turn off your device
- Remove the battery cover and look for the label
- If you still don't see it, remove the battery and look underneath

The iPhone 5 also calls it the MEID. It will be the first 14 digits of the 15-digit number engraved on the case.
