National Numbering Plan & Allocation Process
IMDA regulations play an essential role in managing Singapore's National Numbering Plan to ensure that the number allocation process is fair and transparent to provide a level playing field for competition. The National Numbering Plan provides a set of rules and guidelines for the use and assignment of numbers to telecommunication services delivered over Singapore’s telecommunication networks, including the Public Switched Telephone Network (PSTN), the Radio Network and the Internet, or other Internet Protocol (IP) based networks.
