He IMEI (International Mobile Equipment Identity) number is on all GSM and UMTS mobile phones, commonly found in Europe, Asia, Africa , Australia and increasingly in America. AT&T & T-Mobile are the major US carriers using GSM with IMEI numbers but there are growing numbers of regional carriers who are switching to GSM like Centennial Wireless, Highland Cellular, Dobson Cellular to name a few. Verizon and Sprint phones will generally not have IMEI numbers but rather ESN numbers (similar) unless they have a dual mode module for overseas use. Mobile phone companies can use the number to identify valid subscribers and the type of equipment used. The carrier could thus use the number to remotely disable the phone in the event it is stolen or reported lost and customize data content to be compatible with the type of equipment used, among other things.
