Historical background and development of the country code system

The development of country codes can be traced back to the early 1960s when international telecommunication organizations recognized the need for a standardized numbering system to facilitate global communication. The International Telecommunication Union (ITU), a specialized agency within the United Nations, played a pivotal role in establishing this system. The ITU developed recommendations and guidelines for assigning unique country codes to each member state, including the United States.

Over time, as technology advanced and telecommunications networks expanded worldwide, it became imperative to establish a comprehensive numbering plan that would accommodate increasing demand. In response to this necessity, regional numbering plans were introduced.

For North America, including both Canada and the United States, a specific numbering plan known as the North American Numbering Plan (NANP) was devised. The NANP standardized area codes and phone numbers across these two countries while retaining their individual country codes (+1 for both).

Role of International Telecommunication Union (ITU) in assigning codes

The International Telecommunication Union plays a critical role in overseeing global telecommunication standards and ensuring efficient communication between nations.
