What is a MSISDN?<\/h1>\n\n

The mobile industry is riddled with jargon and so we turn, with a sense of mild dread, to the next tedious acronym.<\/p>\n\n

What on earth is a\u00a0MSISDN<\/strong>?. It\u2019s got something to do with your mobile number right?<\/p>\n\n

Let\u2019s keep this brief and it will all be over soon.<\/p>\n\n

MSISDN stands for Mobile Station International Subscriber Directory Number.\u00a0<\/strong>It\u2019s the unique number that identifies a mobile subscriber. The MSISDN is the mobile subscriber\u2019s phone number including the international country code.<\/p>\n\n

The maximum length of a MSISDN is 15 digits.<\/p>\n\n

Is the MSISDN the same as your mobile number?<\/strong><\/h2>\n\n

Your MSISDN number is the same as your mobile phone number in international format.<\/p>\n\n

In the UK the format is as follows.<\/p>\n\n

What is the format for a MSISDN?<\/strong><\/h2>\n\n

The MSISDN is made up of 3 separate elements<\/p>\n\n

1. County code<\/strong>
The country code is between 1 and 5 characters.
Here are examples of 1, 2 and 3 digit country codes<\/p>\n\n

2. National Destination Code (NDC)<\/strong>
The national destination code (NDC) comes after the country and code and specifies the network that the MSISDN was originally subscribed to. It can also indicate the region of a country where MSISDN was first registered.<\/p>\n\n

3. Subscriber Number (SN)<\/strong>
The subscriber number (SN) is unique to the individual and allows the mobile phone networks to deliver voice, text and data to a subscriber.<\/p>\n\n

Is the MSISDN attached to the mobile phone?<\/strong><\/h2>\n\n

The MSISDN is not attached to a specific device and the phone SIM can be inserted into any make or model of mobile phone.<\/p>\n\n

The MSISDN can also be ported from one network to another.<\/p>\n\n

What is the difference between an MSISDN and an IMSI?<\/strong><\/h2>\n\n

As we\u2019ve been discussing, the MSSISDN is the mobile number or a subscriber.<\/p>\n\n

The IMSI number (International Mobile Subscriber Identity) is a technical identification of a mobile subscriber that\u2019s used by the networks to send and receive voice calls, data and texts.<\/p>\n\n

The IMSI number is stored on the SIM and is often required if someone wants to switch from one mobile network provider to another.<\/p>\n\n

What is the + for in an MSISDN?<\/strong><\/h2>\n\n

The plus sign is used as an alternative to 00 when using mobile numbers in international format.
There are multiple ways that mobile numbers can be formatted and the + sign is one of the conventions used.<\/p>\n\n
