Rufnummernblock (German for “telephone number block”) refers to a contiguous range of telephone numbers assigned to a specific geographic area or service provider. Each block consists of a unique prefix, followed by a set of sequential numbers.
Rufnummernblocks play a crucial role in telecommunication networks, enabling efficient call routing and network management. They provide a structured and organized system for assigning and managing telephone numbers, ensuring that each number is unique and can be easily identified. Rufnummernblocks also facilitate the portability of telephone numbers, allowing users to retain their numbers when changing service providers within the same geographic area.
