A numeric sequence, twelve digits in length, is utilized to identify a specific subscriber within a mobile network, typically on an international scale. This identifier allows for direct communication via voice calls and text messaging, facilitating connectivity with individuals across geographical boundaries. For example, a sequence beginning with a country code, followed by a network operator code and a unique subscriber number, constitutes such an identifier.
This identification method is crucial for global telecommunications. It enables efficient routing of calls and messages, ensuring that they reach the intended recipient regardless of location. The system builds upon earlier numbering schemes but accommodates a significantly larger subscriber base due to the increased digit allocation. This has been vital in supporting the exponential growth of mobile communication globally, fostering personal and professional connections.
