An Electronic Serial Number (ESN) is a unique identifier assigned to every Verizon CDMA device. It is used to identify the device on the Verizon network and to prevent it from being used on other networks. If you are thinking of buying a used Verizon device, it is important to check the ESN to make sure it has not been reported lost or stolen.
There are a few different ways to check the ESN of a Verizon device. One way is to call Verizon customer service at 1-800-922-0204. You will need to provide the representative with the device’s phone number or account number. Another way to check the ESN is to use Verizon’s online ESN checker. You can find the ESN checker on Verizon’s website at https://www.verizonwireless.com/support/esn-meid-checker/.
