How do area codes help route calls across the U.S. and Canada, and why were they first introduced in the 1940s? How has the system evolved since then?

Area codes play a crucial role in routing telephone calls across the U.S. and Canada by dividing regions into specific numbering zones. Introduced in the 1940s as part of the North American Numbering Plan (NANP), area codes allowed for automated long-distance dialing without the need for operator assistance. Over time, with the massive growth of mobile phones, fax machines, and internet services, the demand for new numbers increased dramatically. Today, many regions share multiple area codes, and ten-digit dialing has become common even for local calls.
