MSISDN stands for Mobile Station International Subscriber Directory Number. Simply put, it is a unique identifier that is assigned to every mobile phone user. It is a 15-digit number that is used to identify a mobile phone number internationally.

How is MSISDN different from other mobile phone numbers?

There are different types of mobile phone numbers, such as IMEI, IMSI, and MSISDN. IMEI (International Mobile Equipment Identity) is a unique identifier for a mobile device, while IMSI (International Mobile Subscriber Identity) is a unique identifier for a mobile phone user. MSISDN, on the other hand, is a unique identifier for a mobile phone number.

How is MSISDN structured?

MSISDN is structured in a specific way. It consists of three parts:

– Country code (CC): The first three digits of the MSISDN represent the country code. For example, +90 represents Turkey.
– National destination code (NDC): The next two or three digits represent the NDC. This identifies the mobile network operator within the country.
– Subscriber number (SN): The remaining digits represent the subscriber number.

1. Identification
