The following table describes common acronyms related to BlackBerry smartphones.

Acronym Description

ESN

electronic serial number

The ESN is a unique number that identifies a BlackBerry smartphone for Code Division Multiple Access (CDMA) and Mobitex® networks. The ESN is printed on the label on the back of the BlackBerry smartphone underneath the battery.

The first section of the ESN is the service provider distinction code assigned by the Governing Body for Wireless Communications. The second section of the ESN is the serial number of the BlackBerry smartphone.

The ESN is comparable to the IMEI, which is used to identify BlackBerry smartphones for other networks.

MEID

Mobile Equipment Identifier

The MEID identifies a BlackBerry smartphone for CDMA and Mobitex networks. It was created to replace ESNs, which are nearing exhaustion.

ICCID

Integrated Circuit Card Identifier

An ICCID is a unique number assigned to each SIM card. To see the ICCID on the BlackBerry smartphone, go to Options > SIM Card.

IMEI

International Mobile Equipment Identity

The International Mobile Equipment Identity is a unique number that identifies a particular piece of wireless equipment (for example, a BlackBerry smartphone).

It is 15 digits long. The IMEI is printed on the label on the back of a BlackBerry smartphone for Global System for Mobile communications® (GSM®)/General Packet Radio Service (GPRS) networks.

The IMEI is comparable to the ESN, which is used to identify BlackBerry smartphones for CDMA and Mobitex networks.

IMSI

International Mobile Subscriber Identity

An IMSI is a unique number that identifies a SIM card. It is 15 digits long and is made up of a 3-digit country code, a 3-digit service provider code, and a 9-digit unique ID.

Not all wireless networks use SIM cards (for example, CDMA does not).
