As the telephone network grew, the need for an automated, standardized system became apparent, leading to the development of the modern numeric format for telephone numbers. A phone number usually consists of several parts: country code, area code, and local number. The country code indicates the country associated with the number, and the area code usually corresponds to a specific geographic area within the country.


Local numbers connect to specific phone lines or devices within the area. This layered system ensures that calls are routed efficiently even across national borders. of telephone numbers was the azerbaijan phone number library introduction of the North American Numbering Plan (NANP) in 1947. This system established a standardized format for phone numbers in the United States, Canada, and several other countries, using a three-digit area code followed by a seven-digit local number.


NANP is designed to meet the growing demand for telephone services while maintaining compatibility with existing infrastructure. Similar systems were developed in other parts of the world, leading to the international standardization of telephone numbers under the International Telecommunications Union (ITU). The rise of mobile telephony at the end of the 20th century added new complexity to the world of phone numbers.
