The sequence of digits used to reach landlines and mobile devices in the Egyptian capital consists of a designated prefix. It is an essential component when dialing into the city from locations outside of Egypt, or sometimes even from within the country depending on the specific network and technology utilized. As an illustration, to connect to a landline within the metropolitan region from abroad, one must first dial the international access code, then the country code for Egypt, followed by the specific prefix for the area, and finally the local number.
This numerical designator is crucial for international telecommunications, enabling seamless connection to individuals and businesses within the populous capital. Its implementation facilitates commerce, diplomacy, and personal communication, contributing significantly to the city’s global connectivity. The current numbering plan has evolved over time, adapting to the increasing demand for telephone services and the introduction of mobile technology.
