Techopedia explains Mobile Station International Subscriber Directory Number (MSISDN)

A MSISDN uniquely classifies a subscription in the Global System for Mobile Communications (GSM) or Universal Mobile Telecommunications System (UMTS) networks. It is the telephone number of the Subscriber Identity Module (SIM) card displayed on mobile or cellular phones.

MSISDN numbering adheres to numbering plans defined in ITU Telecommunications Standardization Sector (ITU-T) recommendation E.164. The MSISDN and International Mobile Subscriber Identity (IMSI) are essential to identifying mobile subscribers. The IMSI usually identifies the SIM and is used as a subscriber database key. The MSISDN is the number dialed to bond calls to mobile phones.

A MSISDN may be written in various ways, depending on the source or standardization body and is limited to 15 digits, excluding prefixes.
