How MSISDN Works
Technical Aspects of MSISDN
The MSISDN is a structured number that comprises several components essential for routing calls and messages across mobile networks. It includes the country code, which identifies the country of origin, the national destination code, which is indicative of the operator or the region, and the subscriber number, which is unique to each user. This format ensures that the MSISDN can be universally recognised and routed correctly across international boundaries. The technical construct of MSISDN means that it must comply with international numbering plans set by bodies such as the International Telecommunication Union (ITU). These standards facilitate interoperability between different networks worldwide.
