These codes connect diverse geographical areas, each distinct region represented by a specific area code. However, not all regions share the same number of codes.

How Are Area Codes Assigned?

The North American Numbering Plan Administration (NANPA) follows a systematic and strategic process to assign area codes in the United States. First, NANPA evaluates the need for new codes based on population growth, demand for telecommunications services, and geographic considerations. The objective is to facilitate an efficient, orderly distribution that aligns with the evolving landscape of communication needs.

As regions expand and the requirement for additional phone numbers escalates, NANPA introduces new area codes. This addition maintains the telecommunication network's capacity to serve the growing demands of the new phone numbers in the region.
