​​Pursuant to the powers granted to the Communications, Space & Technology Commission​ under the Telecom Act and its Bylaws, the Commission prepares and manages the National Numbering Plan and updates it periodically to meet the needs of future growth, provide the flexibility required to accommodate the capabilities and usage of different new telecom technologies and services, ensure the availability of numbers, and maintain consistency with ITU-T Recommendations. The National Numbering Plan sets out the principles, rules and guidelines for the management of numbering resources for all types of telecom services in the Kingdom. The most important of these principles are to meet the requirements of telecom services provision by the licensed service providers and the application of the transparency and equity principles adopted by the Commission in all its work. The Plan also describes the regulatory and technical principles related to number structure, allocation rules, and other relevant numbering matters related to communication services, such as Public Switched Telephone Network (PSTN) and Public Mobile Networks.  As numbers are a limited national resource, they must be used  efficiently and managed in such a way as to ensure their availability to meet current and future demand.
