History and Evolution of Area Code 520
Before 1995, the entire state of Arizona operated under a single area code: 602. As Arizona's population boomed and the demand for telephone lines surged, particularly with the rise of mobile phones and fax machines, the need for an additional area code became critical. This led to the creation of area code 520 on March 19, 1995, initially covering all areas outside the Phoenix metropolitan area. This split aimed to alleviate the strain on the existing 602 area code and provide ample numbering resources for the rapidly growing state.
However, the demand for telephone numbers continued to rise even with the introduction of 520. This necessitated a further split in 2001, resulting in the creation of area code 928. This second split refined the boundaries, assigning 928 to the northern and western portions of the state, while 520 remained dedicated to southeastern Arizona. This historical context highlights the dynamic nature of telecommunications infrastructure and its responsiveness to population growth and technological advancements.
