Area code 520 was used as a split from the more original area code 602, and this split was set into effect on March the nineteenth, nineteen ninety-five (1995). Area code 520 would later go on to be split itself, creating the area code 928 to serve even more of the state of Arizona.
The three major establishments that led to this were Tuscon and Flagstaff's expansion needs.
Some of the counties that are using area code 520 include Pima and Santa Cruz, totally 12 counties that are covered by this calling code.
520 also covers 74 cities, some of which being Tempe, Mammoth, Scottsdale and Ajo.
The total population that currently resides under this code is right around one point five (1.5) million residents.
520 mainly covers the majority of the south eastern section of Arizona, only leaving a small section just to the left of it on the south western portion of that state.
Several protected national forests are in the area including Coronado National Forest, and some of the television stations under 520 are KOLD-TV 13, KVOA 4 and KWBA 58.
Pima Community College is located here and so is Northern Arizona University.
Mentionable sports teams would be University of Arizona Wildcats, Arizona Diamondbacks and the Tuscon Sidewinders.
