All mobile devices with cellular capability have unique identification numbers that are used to identify devices that use a GSM cellular network. The International Mobile Equipment Identity (IMEI) number enables a network provider to lock a stolen device out of their network. The IMEI number is located on the payment terminal's shipping box and is also located on label on the back of the payment terminal (same location as the serial number).
If the IMEI number is illegible or missing, you can retrieve it directly from the payment terminal.
