520 Area code

Tucson became a part of the US in 1856 and was incorporated in 1877. The University of Arizona was established in 1885 and became a major foundation for the economy and growth of the city. Arizona became a state in 1912 and the city continued to expand. Veterans also moved to Tucson in the early 1900’s to take advantage of the dry air to help with a plague of respiratory problems after World War I. The population almost doubled between 1950 and 1960 and area code 520 has seen steady growth in the past decades. Now Tucson is the second largest city in Arizona and the 33rd biggest city in the United States. (Source:

Within two years of its creation, however, 520 was already close to exhaustion due to the rapid growth of the Tucson area (and to a lesser extent Yuma and Flagstaff) as well as the proliferation of cell phones and pagers. In 2001, the northern and western portions of the old 520 split off as area code 928. All of Pima, Santa Cruz and Cochise counties, most of Pinal County and part of far southern Maricopa County kept 520, while Yuma and La Paz counties, far western Maricopa County and all of northern Arizona were switched to 928.

Area code 520 is a North American telephone area code for the region covering Tucson in Arizona and most of the Southern region of the state. It was created in 1995 when area code 602 was split. Initially, the state of Arizona was served by a single area code 602 that was created in 1947. As the state's population expanded it was clear that it needed a second area code. This is what informed the creation of the 520 area code. (Source: www.projecthatch.co)
