What is an "area code"?
An area code is a set of digits used in a phone number to identify a specific geographic region within a country. It helps direct the call to the correct location, whether it is a city, district, or specific area within a larger region. In many countries, area codes are part of a larger telephone numbering system that ensures calls are sent to the proper local network.
Example
I accidentally dialed the wrong area code when trying to reach my friend in another city.
Before calling a different region, make sure you include the correct area code.
My phone automatically recognizes the area code and shows the city name.
