Mobile Equipment IDentifier (MEID) is the world's only 56bit mobile terminal identification number. The identification number will be burned into the terminal and can not be modified. Can be used to identify and track mobile devices. Since the ESN segment is a limited resource, it is essentially exhausted and there may be a small number of recovered segments, so a 56-bit MEID segment is developed to replace the 32-bit ESN segment. MEID is mainly assigned to CDMA handsets.
