MSISDN

Mobile Station International Subscriber Directory Number

Description

MSISDN stands for Mobile Station International Subscriber Directory Number. It is a unique identifier for a mobile phone number, which is used in telecommunications to identify a subscription to a mobile network. The MSISDN is usually composed of the country code, the National Destination Code (NDC), and the subscriber number, providing a comprehensive way to route calls and messages to the correct individual or device. In the context of Non-Human Identities (NHIs), MSISDNs can also be assigned to devices that do not have a human user, such as IoT devices, M2M communications, and other automated systems that require mobile connectivity. This allows for seamless communication and management of devices that operate independently of human interaction while still being integrated into the broader telecommunications framework. The use of MSISDNs in NHIs is critical for ensuring robust data transmission and connectivity for various applications, including smart meters, connected vehicles, and remote monitoring systems.

Examples

  • An IoT sensor located in a remote field that uses an MSISDN for sending data back to a central server.
  • A connected vehicle that has an MSISDN for receiving updates and transmitting vehicle diagnostics.

Additional Information

  • MSISDNs can be provisioned for temporary or permanent use depending on the device's connectivity needs.
  • The management of MSISDNs for NHIs often involves specific telecom regulations and provisioning processes.
