MSISDN (Mobile Station International Subscriber Directory Number)

An MSISDN number uniquely identifies a subscription in a GSM or a UMTS mobile network. An MSISDN is the phone number associated with a single SIM card, in other words, the number you call or send an SMS message to. The ITU-T recommendation E.164 limits the maximum length of an MSISDN to 15 digits. 1-3 digits are reserved for country code. Prefixes are not included (e.g., international dialing codes such as 00 or + prefixes). Minimum length of the MSISDN is not specified by ITU-T but is instead specified in the national numbering plans by the telecommunications regulator in each country. Virtual Numbers are also MSISDNs.
